-## 🎯 The Problem - -Authentication is not business logic, yet every project rewrites it. Developers face three painful choices: - -1. **Rewrite auth logic** for every project β€” risky, inconsistent, time-consuming -2. **Use hosted auth services** β€” vendor lock-in, users aren't yours, requires internet -3. **Use framework-specific tools** β€” tied to Express, Django, Next.js β€” not reusable - -## πŸ’‘ The Solution - -CrydenSync is an **embeddable authentication engine** that gives you a standard, reusable auth system you control: - -```go -package main - -import ( - "context" - "fmt" - "log" - - "github.com/crydensync/cryden" -) - -func main() { - // Create context - ctx := context.Background() - - // 1.

-## 🎯 The Problem - -Authentication is not business logic, yet every project rewrites it. Developers face three painful choices: - -1. **Rewrite auth logic** for every project β€” risky, inconsistent, time-consuming -2. **Use hosted auth services** β€” vendor lock-in, users aren't yours, requires internet -3. **Use framework-specific tools** β€” tied to Express, Django, Next.js β€” not reusable - -## πŸ’‘ The Solution - -CrydenSync is an **embeddable authentication engine** that gives you a standard, reusable auth system you control: - -```go -package main - -import ( - "context" - "fmt" - "log" - - "github.com/crydensync/cryden" -) - -func main() { - // Create context - ctx := context.Background() - - // 1. Create engine (in-memory storage - perfect for testing) - engine := cryden.New() - fmt.Println("βœ… Engine created") - - // 2. Sign up a new user - email := "alice@example.com" - password := "SecurePass123" - - user, err := cryden.SignUp(ctx, engine, email, password) - if err != nil { - log.Fatalf("❌ SignUp failed: %v", err) - } - fmt.Printf("βœ… User created: %s (%s)\n", user.ID, user.Email) - - // 3. Login - tokens, rateLimit, err := cryden.Login(ctx, engine, email, password) - if err != nil { - log.Fatalf("❌ Login failed: %v", err) - } - fmt.Printf("βœ… Login successful!\n") - fmt.Printf(" Access Token: %s...\n", tokens.AccessToken[:50]) - fmt.Printf(" Refresh Token: %s...\n", tokens.RefreshToken[:50]) - fmt.Printf(" Rate Limit Remaining: %d\n", rateLimit.Remaining) - - // 4. Verify token - userID, err := cryden.VerifyToken(engine, tokens.AccessToken) - if err != nil { - log.Fatalf("❌ Token verification failed: %v", err) - } - fmt.Printf("βœ… Token verified for user: %s\n", userID) - - // 5. Logout - err = cryden.Logout(ctx, engine, tokens.RefreshToken) - if err != nil { - log.Fatalf("❌ Logout failed: %v", err) - } - fmt.Println("βœ… Logout successful") - - // 6. Try to use logged out token (should fail) - _, err = cryden.RefreshToken(ctx, engine, tokens.RefreshToken) - if err != nil { - fmt.Printf("βœ… Expected error after logout: %v\n", err) - } - - fmt.Println("\nπŸŽ‰ All tests passed!") -} - -``` -[View full example β†’](examples/complete/main.go) - -✨ Features - -βœ… v1.0.0 (Current) - -Β· Email/password authentication β€” Secure, bcrypt hashed -Β· JWT access tokens β€” Short-lived, stateless -Β· Opaque refresh tokens β€” Stored in DB for revocation -Β· Rate limiting β€” Per IP with headers (X-RateLimit-*) -Β· Audit logging β€” Track every auth event -Β· Session management β€” Logout single device or all devices -Β· Multiple storage backends β€” Memory, SQLite, PostgreSQL, MongoDB -Β· Complete test suite β€” 90%+ coverage -Β· Offline-first β€” Works without internet, SQLite by default - -🚧 Coming Soon - -Feature Status Target -gRPC API 🚧 Planned v1.1.0 -CLI tool (csax) 🚧 Planned v1.1.0 -Language SDKs (JS, Python, PHP) 🚧 Planned v1.2.0 -MFA/2FA (TOTP) πŸ“… Future v1.3.0 -Magic Links πŸ“… Future v1.3.0 -WebAuthn/Passkeys πŸ“… Future v2.0.0 - -πŸ“¦ Installation - -```bash -go get github.com/crydensync/cryden@v1.0.0 -``` - -```markdown -## πŸ§ͺ Local Development - -Want to hack on CrydenSync itself?

This document covers how the project is structured and what's expected of a change before it's merged. + +## Project structure + +CrydenSync is an embeddable, framework-agnostic Go authentication engine. Key principles that shape every contribution: + +- **Interface-first** β€” every component (storage, hashing, rate limiting, ID/token generation, logging) is defined as an interface before it's implemented. See `store/interfaces.go`, `security/*.go`, `logger/logger.go`. +- **One production implementation per interface in v1/v2** β€” this keeps the core lean. New backend implementations (a second `UserStore`, a different `RateLimiter`, etc.) are welcome, but should be proposed via an issue first so we can agree on the interface shape before code is written. +- **No storage-specific types leak into interfaces** β€” interface methods take and return plain domain types (`store.User`, `store.Session`, primitives), never `*sql.DB`, `*pgxpool.Pool`, or similar. This is what keeps implementations swappable. +- **Framework-agnostic** β€” the engine never infers caller context (IP, user agent, etc.) internally. Anything like that is an explicit parameter passed in by the caller. +- **Security-critical config fails loud** β€” no default JWT secret, no silent fallback for anything security-relevant. If in doubt, an error is safer than a default. + +## Before you open a PR + +1. **Open an issue first** for anything beyond a small fix β€” bug fixes, typos, and doc corrections can go straight to a PR, but new features or interface changes should be discussed first. +2. **Tests are required**, not optional, for any change to `auth/`, `token/`, `session/`, or `security/` β€” these are the security-critical packages. A PR touching refresh token rotation, password hashing, or session ownership checks without a corresponding test will be asked to add one before merge. +3. **Run the full suite before submitting:** + ```bash + go build ./... + go vet ./... + go test ./... + ``` +4. **Keep PRs focused.** One logical change per PR β€” easier to review, easier to revert if something's wrong. + +## Reporting a security issue + +Please do **not** open a public issue for a security vulnerability. See `SECURITY.md` (or contact the maintainer directly) for responsible disclosure. + +## Code style + +- Standard `gofmt`/`goimports` formatting β€” no exceptions. +- Prefer explicit, narrow function parameters over passing around large structs, especially in `auth/`, `session/`, and `token/` β€” makes each function easy to test in isolation. +- Comment the *why*, not the *what*, especially around security decisions (e.g. why an error is generic instead of specific, why a check happens before another). + +## Code of Conduct + +By participating in this project, you agree to abide by the [Code of Conduct](./CODE-OF-CONDUCT.md). \ No newline at end of file diff --git a/README.md b/README.md new file mode 100644 index 0000000..2537348 --- /dev/null +++ b/README.md @@ -0,0 +1,150 @@ +# CrydenSync + +

Run the migration in `store/postgres/migrations/0001_initial_schema.up.sql` against your database. +2. Requires Postgres 13+ (uses the built-in `gen_random_uuid()`). +3.

Defaults to 5 attempts / 15 minutes; override via `Config.LockoutThreshold` and `Config.LockoutDuration`. + +## Email verification / email change + +`RequestEmailChange` and `ConfirmEmailChange` require two additional `Config` fields that are otherwise optional: + +```go +engine, err := cryden.New(cryden.Config{ + // ...required fields... + Verifications: postgres.NewVerificationStore(db), // or memory.NewVerificationStore() + EmailSender: myEmailSenderImpl, // you implement notify.EmailSender +}) +``` + +The engine never sends email itself β€” implement `notify.EmailSender` against whatever provider you use (SendGrid, SES, SMTP), and build the actual verification URL yourself; the engine only hands you a raw token, it has no idea what your app's domain or routes look like. Calling `RequestEmailChange` without these configured returns `cryden.ErrEmailChangeNotConfigured` rather than panicking. + +## What's in v2 + +- Signup, login, logout (single device + all devices) +- JWT access tokens + rotating opaque refresh tokens with theft/reuse detection +- Session listing and revocation +- Change password (requires current password, revokes all other sessions) +- Change email (requires verification of the new address before it takes effect) +- Delete account (requires current password) +- Persistent, DB-backed account lockout after repeated failed login attempts β€” survives restarts, correct across multiple instances +- Email verification primitives (token issue/confirm) β€” delivery is pluggable via the `notify.EmailSender` interface, the engine never sends email itself +- Rate limiting, bcrypt password hashing, audit logging +- One storage backend: Postgres (interface-based, more can be added later) + +## What's not in v2 (yet) + +CLI, HTTP API, and language SDKs are separate repositories that wrap this engine β€” this repo is the core library only.

charset=UTF-8 Content-Transfer-Encoding: 8bit Login takes two new params (totpStore, pendingIssuer), both nil-safe β€” an Engine built without Config.TOTP passes nil for both and Login behaves exactly as before. After password verification, if the account has a confirmed TOTP secret, Login now issues a pending token and returns *ErrTOTPRequired instead of tokens. Extracts the post-verification tail (session creation, access token issuance, audit record) into a shared finishLogin helper, used by both Login (password-only path) and CompleteLoginWithTOTP (second-factor path), so a completed login produces an identical session regardless of which path got it there. This changes auth.Login's internal signature, not the public facade β€” cryden.Login(ctx, e, email, password, callerIP, userAgent) is unchanged; auth is documented as implementation detail, imported only by the top-level cryden package. Updates existing lockout_test.go/login_test.go call sites to pass nil, nil for the two new params. --- auth/lockout_test.go | 14 +++++------ auth/login.go | 56 +++++++++++++++++++++++++++++++++++++++++--- auth/login_test.go | 12 ++++++---- 3 files changed, 67 insertions(+), 15 deletions(-) diff --git a/auth/lockout_test.go b/auth/lockout_test.go index 46cadde..e62eb39 100644 --- a/auth/lockout_test.go +++ b/auth/lockout_test.go @@ -16,7 +16,7 @@ func TestLogin_LocksAccountAfterThreshold(t *testing.T) { threshold := 3 for i := 0; i < threshold; i++ { - _, err := Login(ctx, users, sessions, hasher, ids, refreshGen, jwtIssuer, limiter, audit, log, + _, err := Login(ctx, users, sessions, nil, hasher, ids, refreshGen, jwtIssuer, nil, limiter, audit, log, "proguy@example.com", "wrong-password", "1.2.3.4", "test-agent", threshold, time.Minute) if err != ErrInvalidCredentials { t.Fatalf("attempt %d: expected ErrInvalidCredentials, got %v", i+1, err) @@ -26,7 +26,7 @@ func TestLogin_LocksAccountAfterThreshold(t *testing.T) { // One more attempt, even with the CORRECT password, must now be // rejected as locked β€” the lock isn't just "N more wrong guesses // fail," it blocks everything including a legitimate login. - _, err := Login(ctx, users, sessions, hasher, ids, refreshGen, jwtIssuer, limiter, audit, log, + _, err := Login(ctx, users, sessions, nil, hasher, ids, refreshGen, jwtIssuer, nil, limiter, audit, log, "proguy@example.com", "correct-password", "1.2.3.4", "test-agent", threshold, time.Minute) if err != ErrAccountLocked { t.Errorf("expected ErrAccountLocked, got %v", err) @@ -44,12 +44,12 @@ func TestLogin_SuccessfulLoginResetsFailedAttempts(t *testing.T) { threshold := 5 // Two failed attempts, below threshold. for i := 0; i < 2; i++ { - Login(ctx, users, sessions, hasher, ids, refreshGen, jwtIssuer, limiter, audit, log, + Login(ctx, users, sessions, nil, hasher, ids, refreshGen, jwtIssuer, nil, limiter, audit, log, "proguy@example.com", "wrong-password", "1.2.3.4", "test-agent", threshold, time.Minute) } // A successful login should reset the counter. - _, err := Login(ctx, users, sessions, hasher, ids, refreshGen, jwtIssuer, limiter, audit, log, + _, err := Login(ctx, users, sessions, nil, hasher, ids, refreshGen, jwtIssuer, nil, limiter, audit, log, "proguy@example.com", "correct-password", "1.2.3.4", "test-agent", threshold, time.Minute) if err != nil { t.Fatalf("expected successful login, got %v", err) @@ -72,11 +72,11 @@ func TestLogin_LockExpiresAfterDuration(t *testing.T) { threshold := 1 shortLock := 10 * time.Millisecond - Login(ctx, users, sessions, hasher, ids, refreshGen, jwtIssuer, limiter, audit, log, + Login(ctx, users, sessions, nil, hasher, ids, refreshGen, jwtIssuer, nil, limiter, audit, log, "proguy@example.com", "wrong-password", "1.2.3.4", "test-agent", threshold, shortLock) // Immediately after: locked. - _, err := Login(ctx, users, sessions, hasher, ids, refreshGen, jwtIssuer, limiter, audit, log, + _, err := Login(ctx, users, sessions, nil, hasher, ids, refreshGen, jwtIssuer, nil, limiter, audit, log, "proguy@example.com", "correct-password", "1.2.3.4", "test-agent", threshold, shortLock) if err != ErrAccountLocked { t.Fatalf("expected ErrAccountLocked immediately after lock, got %v", err) @@ -85,7 +85,7 @@ func TestLogin_LockExpiresAfterDuration(t *testing.T) { time.Sleep(20 * time.Millisecond) // After the lock duration passes, login should succeed again. - _, err = Login(ctx, users, sessions, hasher, ids, refreshGen, jwtIssuer, limiter, audit, log, + _, err = Login(ctx, users, sessions, nil, hasher, ids, refreshGen, jwtIssuer, nil, limiter, audit, log, "proguy@example.com", "correct-password", "1.2.3.4", "test-agent", threshold, shortLock) if err != nil { t.Errorf("expected login to succeed after lock expiry, got %v", err) diff --git a/auth/login.go b/auth/login.go index a9e4dd9..0e96862 100644 --- a/auth/login.go +++ b/auth/login.go @@ -15,6 +15,12 @@ import ( // token pair). callerIP and userAgent are required, caller-supplied β€” // never inferred inside the engine. // +// totpStore and pendingIssuer are optional (nil if Config.TOTP isn't +// set).

charset=UTF-8 Content-Transfer-Encoding: 8bit LoginWithOAuth predated the second-factor work and did its own inline session issuance β€” an account with TOTP/a passkey enrolled would log straight in via a linked OAuth identity with NO second-factor check at all. It now takes totpStore/webauthnStore/recoveryCodeStore params (all nil-safe) and routes through the same completePrimaryAuth gate password/magic-link login use. Confirming an OAuth identity proves the primary factor, exactly like a correct password; it was never meant to bypass a confirmed second one. The pre-fix code also tagged its login_success audit event with which provider was used. completePrimaryAuth/finishLogin gained an extraMetadata param specifically to preserve that detail through the shared helper β€” LoginWithOAuth passes {"provider": provider}, other callers pass nil. While threading recoveryCodeStore through (added alongside TOTP/ WebAuthn in the same signature change, since Go requires every call site to move together or the build breaks), completePrimaryAuth also gained the recovery-code safety property: "recovery_code" is only ever added to Methods when a real factor (totp/webauthn) is also present. An account that disabled its last real second factor but still has unconsumed recovery codes sitting in storage must never have those codes silently become a permanent standalone backdoor. Updates existing lockout_test.go/login_test.go/login_totp_test.go/ magiclink_test.go/oauth_test.go call sites for both signature changes. --- auth/lockout_test.go | 14 +++++----- auth/login.go | 58 ++++++++++++++++++++++++++++++++--------- auth/login_test.go | 10 +++---- auth/login_totp_test.go | 10 +++---- auth/magiclink.go | 3 ++- auth/magiclink_test.go | 12 ++++----- auth/mfa.go | 2 +- auth/oauth.go | 57 ++++++++++++++-------------------------- auth/oauth_test.go | 6 ++--- auth/webauthn.go | 2 +- cryden.go | 35 ++++++++++++++++++++++--- 11 files changed, 126 insertions(+), 83 deletions(-) diff --git a/auth/lockout_test.go b/auth/lockout_test.go index d8f6ef6..05aa6e4 100644 --- a/auth/lockout_test.go +++ b/auth/lockout_test.go @@ -16,7 +16,7 @@ func TestLogin_LocksAccountAfterThreshold(t *testing.T) { threshold := 3 for i := 0;

entirely, single-use enforcement, case/whitespace-insensitive matching, a wrong code rejected, and the two Login-level safety properties: recovery_code is only ever advertised alongside a real factor,

When in doubt +which bucket a new integration falls into, ask: "does using this +feature necessarily mean cryden talks to some external service over +the network?" If yes β†’ zero-implementation interface, host supplies +one. If it's local computation/crypto only β†’ ship one real +implementation using a well-vetted library, same as TOTP/WebAuthn. + +**Config fields for optional features are nil-safe.** Unset β†’ the +facade function returns a clear `cryden.ErrXNotConfigured`, never a +panic. The one deliberate exception: `Config.PasswordPolicy` has no +"off" state β€” leaving it as the literal zero value +(`security.PasswordPolicy{}`, compared as a **whole struct**, not by +checking one field) applies `security.DefaultPasswordPolicy` +automatically. Password strength isn't opt-in the way 2FA methods are. + +**Fail loudly, never silently insecure.** Security-critical +misconfiguration (missing JWT secret, missing required store) is a +hard error from `New()`, not a runtime surprise. + +**Storage pattern for a new pluggable feature:** +1. Type + interface in `store/interfaces.go`. +2. `store/memory/_store.go` β€” test implementation. +3. `store/postgres/_store.go` β€” production implementation. If + storing a rich/evolving struct (e.g. a third-party library's own + type), store it as a JSON blob column rather than decomposing every + field β€” see `webauthn_credentials.credential_data` for the pattern. + **Passing a Go `[]byte` to a `jsonb` column via `lib/pq` sends it as + `bytea` on the wire and fails** β€” cast to `string(...)` first. +4. `store/postgres/migrations/000N_.up.sql` + `.down.sql`. +5. Wire into `Config`, `Engine`, and the `cryden` facade. + +**Error patterns:** +- Simple binary failure β†’ sentinel `var ErrX = errors.New(...)`. +- Failure that carries data the caller needs β†’ a struct type with an + `Error()` method, retrieved via `errors.As` (see + `ErrSecondFactorRequired{PendingToken, Methods}`, + `ErrPasswordPolicyViolation{Violations []string}`, + `ErrOAuthEmailConflict`). Never encode structured data into an error + *string* for a caller to parse. +- Enumeration-avoidance: when a wrong input and a nonexistent-resource + input would otherwise return different errors or take different + time, they must return the identical error AND the identical + execution path (see `Login`'s nonexistent-email case, which still + pays bcrypt's cost via a dummy hash β€” a fixed historical bug, worth + reading `auth/login.go`'s comment on it once). + +**Audit logging:** every security-relevant event gets an +`AuditEventType` constant in `store/interfaces.go` and is recorded via +`store.AuditStore`. Routine input-validation failures (a malformed +email, a too-short password) are NOT audited β€” too noisy, not +security-relevant. A confirmed breach, a failed second-factor attempt, +a completed login, an account lock β€” those are. + +**Second-factor gate:** every *primary* authentication path (password +`Login`, `CompleteMagicLink`, `LoginWithOAuth`) routes through +`completePrimaryAuth` in `auth/login.go`. It collects confirmed +methods (`totp`, `webauthn`, `recovery_code` β€” the last **only** +alongside a real factor, never standalone, see the comment there for +why) and either pauses with `*ErrSecondFactorRequired{PendingToken, +Methods}` or calls `finishLogin` to issue tokens. **Any new primary +auth method MUST route through `completePrimaryAuth`, never +reimplement session issuance inline** β€” `LoginWithOAuth` shipped with +exactly that bug once; it's fixed now, don't reintroduce the pattern. + +**Encryption vs. hashing:** passwords, tokens, recovery codes β†’ +one-way hash (bcrypt for passwords; SHA-256 via `token.HashToken` for +everything else, since those are already high-entropy random values, +not human-guessable secrets β€” bcrypt's slow-hash property defends +against a different threat than these need). TOTP secrets and WebAuthn +ceremony state β†’ `security.Encryptor` (reversible), because the engine +must recover the original plaintext value later. Never mix these up. + +**Fixed, non-configurable security TTLs:** `mfaPendingTTL` (5 min), +`magicLinkTTL` (15 min) are intentionally hardcoded constants, not +`Config` fields. A tuning knob here just invites a deployment to widen +a narrow security window. Follow this precedent for any new short- +lived credential β€” don't make it configurable without a real reason. + +## Known platform gotchas (don't rediscover these) + +- No network access to `proxy.golang.org` in some sandboxed tool + environments β€” `go build`/`go test`/`go mod tidy` may not be + runnable there. Say so plainly; don't claim untested code compiles. +- `lib/pq` fails outright on Termux/Android (`os/user.Current` + unimplemented for `GOOS=android`) β€” not something to fix, the human + works around it with `proot-distro ubuntu` or a real machine. +- Supabase connection strings must use the **session pooler** (port + 5432), not the transaction pooler (6543) or a direct connection. +- `virtualwebauthn`'s simulated credential starts its signature + counter at 0 and never auto-increments on its own β€” and 0 is itself + a legitimate, spec-allowed value for a real authenticator too. Don't + assert a counter "must be nonzero" in any WebAuthn test; if you need + to test counter pass-through, set it explicitly before the call. +- **Never mutate the real `crypto/rand.Reader` package-level global in + a test**, on any platform β€” on at least one real environment, a + failed read through that specific global hits the Go runtime's own + unrecoverable fatal-error path (a process crash, not a normal test + failure), not a catchable error. If you need to test an entropy-read + failure path, inject a fake `io.Reader` into a same-package struct + field instead (see `token.CryptoRandTokenGenerator.randReader` for + the pattern). +- **When you change a shared function's signature, grep the ENTIRE + repo for every call site before committing** β€” + `grep -rn "FunctionName(ctx" --include="*.go" .` β€” not just the + files you remember touching.

Source: `AuditStore.ListByUser` + and/or `SessionStore.ListByUser` β€” check both for whichever + actually has the fields you need at low cost, don't guess, look at + the real interfaces. +- **Failed-attempt velocity**: rate of `login_failed` events per user + AND per IP over a configurable window, via `AuditStore.SearchByType`. +- **Token reuse / session anomalies**: escalate on + `token_reuse_detected` events and unusually high concurrent-session + counts for one user. + +**On a flagged attempt**: record only, never block. New audit event +type(s) for the flag itself (e.g. `anomaly_detected` with a metadata +field describing which signal(s) fired) β€” do not add a new sentinel +error, do not force step-up 2FA, do not hard-block. This was +explicitly decided this way; do not revisit it. + +**Storage**: new `store.AnomalyStore` interface + `store/memory` + +`store/postgres` implementations + migration. Design the interface +around "what does a caller need to query" (e.g. a user's recent known +IPs/devices, recent failed-attempt counts) rather than mirroring audit +events 1:1 β€” this store should make the detector's own reads cheap, +that's the whole reason it's not just more `AuditStore` queries. + +**Where it plugs in**: this most likely runs as part of +`completePrimaryAuth` or right alongside it in `Login`/ +`LoginWithOAuth`/`CompleteMagicLink` β€” after the primary factor is +confirmed, before (or in parallel with) the second-factor check. New +optional `Config.AnomalyDetector` (or similar β€” you decide the exact +field/interface split between "detection logic" and "storage," but +keep detection logic testable independent of storage, same as +everything else in this codebase). Fully additive β€” nil-safe, no +behavior change for an engine that doesn't configure it. + +### 2. Credential-stuffing detection (item 9) β€” overlaps with item 8, don't duplicate + +This is "many accounts failing from one IP" β€” which is *almost* the +same underlying data as item 8's per-IP failed-attempt velocity +signal. **Build the shared detection query once** (as part of item 8's +`AnomalyStore`, if item 8 is done first β€” check `CURRENT-STATE.md`). +This item's real incremental work is likely just: a distinct threshold +tuned for "one IP, many different target accounts" (existing per- +account lockout already handles "one account, many attempts" β€” this +is the gap that doesn't cover), and its own audit event type +(`credential_stuffing_detected`) so it's distinguishable from a +single-account anomaly in monitoring. If item 8 isn't built yet when +you reach this, build the minimal shared piece it needs rather than a +second parallel tracking system. + +### 3. Named/fingerprinted sessions (item 10) β€” genuinely underspecified, use judgment + +Current `store.Session` already has `IP` and `UserAgent`. "Named/ +fingerprinted" most likely means: a human-readable label for "your +active sessions" UI (e.g. "Chrome on Windows β€” San Francisco, CA") +instead of a raw session ID. + +- User-Agent β†’ device/browser string: pure parsing, no network call, + no external API β€” fine to ship as a real engine-side helper (or a + small interface if you think host apps would want to swap parsing + libraries; use your judgment, this is a minor decision either way). +- IP β†’ location string: this DOES require geolocation data from + somewhere. Follow the established rule β€” if it needs an outbound + network call, it's a new interface (e.g. `security.IPGeolocator`) + with **zero shipped implementations**, host supplies one, exactly + like `BreachedPasswordChecker`. Do not bake in a call to any + specific geo-IP service directly. +- If geolocation feels like it belongs entirely at the `api`/host-app + layer instead of the engine (since the engine already exposes raw + IP on every session), that's a legitimate alternative β€” note your + reasoning in `PROGRESS.md` either way, this is the item where the + original backlog line is vaguest and a documented judgment call is + expected. + +### 4. Redis-backed rate limiter (item 11) + +`security.RateLimiter` already exists with one implementation +(in-memory, documented as not safe across multiple instances). This is +a **second real implementation**, not an interface-only integration β€” +Redis is configured infrastructure the host app wires in explicitly +(a connection string/client), the same category as Postgres, not an +arbitrary third-party internet service like HIBP. Ship a real +`security.RedisRateLimiter` (or wherever you decide it should live β€” +probably `security/`, matching where the in-memory one lives) using a +real, well-established Go Redis client library. `Config` gets a new +way to select/configure it (follow how `Users`/`Sessions`/etc. stores +are injected as already-constructed instances, not built internally +from a connection string β€” match that pattern here too). + +--- + +## Tier 3 β€” Infrastructure & Extensibility + +### 5. Argon2id as an additional trusted hasher (item 12) + +Second implementation of `security.Hasher`, not a replacement for +bcrypt. Real design question: how does the engine know which +algorithm a given stored hash used, for a user base that might have a +mix (e.g. mid-migration)? The common answer is sniffing the hash's own +format prefix (`$argon2id$...` vs bcrypt's `$2a$`/`$2b$`) inside a +dispatching `Compare`, while `Hash` always uses whichever algorithm is +currently configured. Build it this way unless you find a strong +reason not to; note the reasoning either way. + +### 6. Additional storage backend beyond Postgres (item 13) + +Every `store.X` interface already exists β€” implement all of them +against a second backend (SQLite is the most likely candidate per +earlier project notes, but check `CURRENT-STATE.md`/`PROGRESS.md` for +anything more specific by the time you get here). Watch for Postgres- +specific assumptions baked into existing interface docs/behavior +(`JSONB` columns, `ON CONFLICT ... DO UPDATE`, `RETURNING`) β€” several +`store/postgres/` implementations lean on these and a different +backend will need different real solutions, not just syntax swaps. + +### 7. Cloud logger integrations (item 14) + +`logger.Logger` already exists with one implementation (console JSON). +Decide interface-only-vs-shipped-implementation the same way as +everything else: does using this necessarily mean an outbound network +call? If yes (calling Datadog's/Better Stack's API directly), lean +toward interface-only, zero shipped implementations β€” most host apps +already have their own logging pipeline wired at their level, and +console-JSON-to-stdout is already the universal integration point +(any log shipper can tail stdout). Only ship a real implementation if +there's a specific strong reason a direct integration adds real value +over "the host app already captures stdout." + +### 8. Extensible JWT claims (item 15) + +Let host apps attach their own data to access tokens. Read +`token/jwt.go`'s current claims struct and `JWTIssuer.Issue` before +proposing anything β€” whatever you add must not weaken the existing +algorithm-confusion protections already there (the `alg: none`/ +signing-method check). Likely shape: `Issue` gains an optional +`extraClaims map[string]interface{}` parameter, or a small +`ClaimsProvider` hook β€” pick whichever fits the existing `Issue` +call sites with the least disruption. + +### 9. API keys / machine-to-machine auth (item 16) + +New concept, not a variant of an existing one β€” no human to prompt, so +this sits outside the second-factor system entirely (confirm this +assumption is right by checking whether M2M auth appears anywhere else +in the codebase already β€” it shouldn't). Needs its own storage +(`store.APIKeyStore`), fast-hash lookup like recovery codes (SHA-256 +via `token.HashToken`, not bcrypt β€” these are high-entropy generated +values, not human passwords), and its own facade functions +(`GenerateAPIKey`, `RevokeAPIKey`, and something that validates a +presented key and returns which user/scope it belongs to). + +### 10. Webhooks (item 17) + +Notify the host app on key events. Same question as everything else +that reaches outward: interface-only, zero shipped implementations +(`notify.WebhookSender` or similar), matching `EmailSender` β€” the +engine surfaces the event, the host app's implementation does the +actual HTTP call, retries, signing, etc. Decide which existing audit +events should also trigger a webhook call (probably a configurable +subset, not all of them) and wire it in wherever `audit.Record` is +already called for those events β€” don't build a second parallel event +bus. + +### 11. Custom email templates (item 18) + +Check `notify.EmailSender`/`notify.MagicLinkSender` as they exist +today first β€” there's a real chance this needs **no engine change at +all**, since the host app's own implementation already owns the +actual email body/template (the engine only ever hands over a raw +token, per `EmailSender`'s own doc comment). If that's true, say so +plainly in `PROGRESS.md` and mark the item done-as-a-non-issue rather +than building something speculative to have built something. + +--- + +## Tier 4 β€” AI-assisted admin features + +**Non-negotiable for all four:** read-only / surface-only. No +automatic action β€” no auto-lock, no auto-config-change, nothing. Every +one of these produces information for a human to act on. + +### 12. Weekly digest (item 19) +Reads `AuditStore`, summarizes in plain English, returns text. Nothing +else. + +### 13. Support-ticket assistant (item 20) +Read-only diagnosis ("why can't user X log in") β€” queries +`AuditStore`/`UserStore`/session state, produces an explanation, never +touches anything. + +### 14. Config tuning advisor (item 21) +Produces a report of suggested config changes. Never applies them. + +### 15. Ask-AI widget (item 22) +The most complex of the four. Needs its own full design pass before +any code β€” at minimum: an LLM provider interface (zero shipped +implementations, host brings their own key/provider, same pattern as +every other external-network-call integration), a defined read-only +query surface, and an explicit answer to how untrusted end-user input +is kept from doing anything beyond reading data (this is exposed to +the host app's own end users, not just admins β€” prompt-injection +surface is real here). Write the design into this section of +`NEXT.md` (or a new file it points to) before writing any code, even +though there's no human to approve it mid-session β€” the design still +needs to exist and be reasoned through in writing, just do it as part +of this same session rather than waiting for a reply. + +--- + +## Tier 5 β€” do not start + +See `CURRENT-STATE.md`.

Negative cases carry the design: first login is clean, a familiar login stays quiet, and a broken store never blocks. --- auth/anomaly_test.go | 531 +++++++++++++++++++++++++++++ config_test.go | 53 +++ security/anomaly.go | 7 +- security/anomaly_test.go | 228 +++++++++++++ store/memory/anomaly_store_test.go | 154 +++++++++ 5 files changed, 969 insertions(+), 4 deletions(-) create mode 100644 auth/anomaly_test.go create mode 100644 security/anomaly_test.go create mode 100644 store/memory/anomaly_store_test.go diff --git a/auth/anomaly_test.go b/auth/anomaly_test.go new file mode 100644 index 0000000..181129d --- /dev/null +++ b/auth/anomaly_test.go @@ -0,0 +1,531 @@ +package auth + +import ( + "context" + "errors" + "strconv" + "testing" + "time" + + "github.com/crydensync/cryden/v2/security" + "github.com/crydensync/cryden/v2/store" + "github.com/crydensync/cryden/v2/store/memory" + "github.com/crydensync/cryden/v2/token" +) + +// anomalyTestThresholds keeps the numbers small so a test can reach a +// velocity threshold in a few calls instead of twenty. +var anomalyTestThresholds = security.AnomalyThresholds{ + Window: 15 * time.Minute, + HistorySize: 20, + UserFailureVelocity: 3, + IPFailureVelocity: 5, + MaxConcurrentSessions: 50, + TokenReuseLookback: 24 * time.Hour, +} + +type anomalyDeps struct { + users *memory.UserStore + sessions *memory.SessionStore + audit *memory.AuditStore + anomalies *memory.AnomalyStore + hasher security.Hasher + ids security.IDGenerator + refresh token.TokenGenerator + jwt *token.JWTIssuer + limiter security.RateLimiter + log testLogger +} + +func newAnomalyDeps(t *testing.T) *anomalyDeps { + t.Helper() + hasher, _ := security.NewBcryptHasher(4) + refreshGen, _ := token.NewCryptoRandTokenGenerator(32) + jwtIssuer, _ := token.NewJWTIssuer("test-secret", time.Minute) + return &anomalyDeps{ + users: memory.NewUserStore(), + sessions: memory.NewSessionStore(), + audit: memory.NewAuditStore(), + anomalies: memory.NewAnomalyStore(), + hasher: hasher, + ids: security.NewUUIDv7Generator(), + refresh: refreshGen, + jwt: jwtIssuer, + limiter: security.NewInMemoryRateLimiter(1000, time.Minute), + log: testLogger{}, + } +} + +// seedUser creates the standard placeholder identity. +func (d *anomalyDeps) seedUser(ctx context.Context, t *testing.T) store.User { + t.Helper() + hash, err := d.hasher.Hash("Tr0ubl3-Fr33!2026") + if err != nil { + t.Fatalf("hashing failed: %v", err) + } + u := storeUser("user-1", "raymondproguy@dev.com", hash) + if err := d.users.Create(ctx, u); err != nil { + t.Fatalf("seeding the user failed: %v", err) + } + return u +} + +// login runs a password login through the real Login path, with the +// anomaly store wired in unless anomalies is explicitly nil. +func (d *anomalyDeps) login(ctx context.Context, anomalies store.AnomalyStore, password, ip, agent string) (Tokens, error) { + return d.loginWith(ctx, anomalies, anomalyTestThresholds, password, ip, agent) +} + +func (d *anomalyDeps) loginWith(ctx context.Context, anomalies store.AnomalyStore, thresholds security.AnomalyThresholds, password, ip, agent string) (Tokens, error) { + return Login(ctx, d.users, d.sessions, nil, nil, nil, anomalies, + d.hasher, d.ids, d.refresh, d.jwt, nil, d.limiter, d.audit, d.log, + "raymondproguy@dev.com", password, ip, agent, 100, time.Minute, thresholds) +} + +func countEvents(t *testing.T, audit *memory.AuditStore, userID string, typ store.AuditEventType) []store.AuditEvent { + t.Helper() + events, err := audit.ListByUser(context.Background(), userID, 100) + if err != nil { + t.Fatalf("listing audit events failed: %v", err) + } + var out []store.AuditEvent + for _, e := range events { + if e.Type == typ { + out = append(out, e) + } + } + return out +} + +// The feature is off until a store is injected, exactly like TOTP and +// recovery codes.

Pure threshold arithmetic +in `security/anomaly.go`, the storage-reading pass in +`auth/anomaly.go`, a `store.AnomalyStore` over a new `login_attempts` +table (memory + postgres + migration `0006`), an `anomaly_detected` +audit event, and `Config.Anomalies` / `Config.AnomalyThresholds`. +Detection is called once from `completePrimaryAuth`, which covers +password, magic-link and OAuth login together. 35 Go tests, a 54-check +smoke test at `cmd/smoketest/anomaly-detection`, and +`docs/testing/anomaly-detection.md`. + +Assumptions made (spec left these open): + +- **Config shape.** `NEXT.md` said "`Config.AnomalyDetector` or + similar β€” you decide." I split it the way the codebase already + splits this kind of thing rather than inventing a third pattern: an + injected optional store (`Config.Anomalies`, nil β‡’ feature off, like + `TOTP`/`WebAuthn`/`RecoveryCodes`) plus a plain config struct + (`Config.AnomalyThresholds`, whole-struct zero β‡’ defaults, like + `PasswordPolicy`). No detector interface: there is nothing here a + host app would want to swap that the thresholds don't already cover, + and an interface would have dragged `store` into `security`. +- **Six signals, not three.** The spec's "new IP/device" and "token + reuse / session anomalies" each carry two distinct meanings, so each + became two signals. A known device on a new IP is travel; a new + device on a known IP is more often a second party. A replayed + refresh token and an unusual live-session count are equally + unrelated. Merging either pair would have made the metadata + ambiguous for exactly the monitoring it exists to feed. +- **Baseline is successes only.** `AnomalyStore.ListRecentSuccesses` + deliberately ignores failures. If failures fed the known-IP list, an + attacker would establish their own address as familiar just by + failing a few times first. +- **First login is never flagged.** `HasLoginHistory` suppresses + new_ip/new_device when the account has no prior success. Otherwise + every account's first login is an anomaly, which is noise. +- **A separate `TokenReuseLookback` (24h) alongside `Window` (15m).** + Failure velocity is a burst happening now; a stolen refresh token + replayed this morning still matters this afternoon. One duration + could not serve both, and unbounded would flag every login the + account ever makes again. +- **Token-reuse history is a bounded 100-event scan** of the user's + audit log, because `AuditStore` has no by-user-and-type query + (`ListByUser` is per-user, `SearchByType` is system-wide). A user + with more than 100 events since their last reuse event misses the + signal. Acceptable for a report-only annotation; adding an + `AuditStore` method for it would have widened the item. +- **Sequencing.** Observations are read before the current attempt is + recorded, so an attempt can never appear in its own baseline. +- **Storage errors degrade to "no evidence,"** never to "everything is + unfamiliar" β€” the latter would flag every login during an outage. + +Verification: `go build ./...`, `go vet ./...` and `go test ./...` all +run clean here with `GOTOOLCHAIN=go1.25.11 GOPROXY=off` (the module +cache has every dependency; only the toolchain download fails without +network, and `/usr/bin/go` is 1.22.2 while `go.mod` needs 1.25.0 β€” +hence the explicit `GOTOOLCHAIN`). The smoke test runs and passes all +54 checks. Postgres was not exercised β€” no database in this +environment; migration `0006` and `store/postgres/anomaly_store.go` +are reviewed-and-compiled only, and section 9 of the manual test guide +covers what to check against a real one. + +Noted in passing, not fixed: `TestLogin_NonexistentUserTimingMatches` +`WrongPassword` in `auth/` is timing-based and flaked once when the +full suite ran packages in parallel (ratio 0.35), then passed on three +consecutive full runs and five isolated ones. Pre-existing and +unrelated to this item β€” it compares two bcrypt durations and is +sensitive to CPU contention. Worth its own small branch if it recurs. + +Next in queue: item 9, credential-stuffing detection. `login_attempts` +already holds the data it needs; `NEXT.md` has the updated spec.
