feat(credentials): implement Component B credential manager with OS

[Edge-Explorer]

CodeRabbit Review Fixes Applied & Verified

Addressed all reviewer feedback items on feat/credential-manager:

1. TRACEPASS_CREDS Validation: Explicitly validates that env_map is a JSON dict, keys are strings, values are dicts, and username/password entries are valid strings before returning. Malformed entries are safely skipped without breaking lookup for subsequent valid domains.
2. Vault JSON & Decrypted Payload Type Guards: Added isinstance(record, dict) check before reading vault fields to prevent AttributeError on non-object JSON (e.g. lists/strings) and convert it to InvalidVaultFormat. Added payload dict validation after AES-256-GCM decryption.
3. Owner-Only Directory Permissions: Enforced 0o700 (rwx------) permissions on ~/.tracepass/ directory creation alongside temporary file 0o600 permissions.
4. Keyring Test Isolation: Isolated test_env_injected_credentials and test_malformed_env_injected_credentials from host OS keyring state using monkeypatch to ensure deterministic CI runs.

🤖 PR Detailed Review & Summary by Gemini Code Intelligence

1. Executive Summary (In Plain English)

This Pull Request introduces a robust and secure credential management system, designated as "Component B," for the Tracepass project. It enables the application to retrieve user authentication credentials from multiple prioritized sources: an in-memory cache, environment variables, the operating system's native credential store (like Windows Credential Manager or macOS Keychain), and a newly implemented AES-256-GCM encrypted local vault. This system is designed to handle sensitive data securely, preventing credentials from being exposed to logs or Large Language Models (LLMs), and includes comprehensive validation and error handling for all credential sources.

2. Motivation & Root Cause Analysis

The primary motivation for this implementation stems from the critical need to securely manage and retrieve authentication credentials within the Tracepass ecosystem, as outlined in Section 4 & Decision 4 of docs/login-engine.md. Before this PR, there was no centralized, secure, and multi-source mechanism for credential resolution, leading to several potential shortcomings:

1. Lack of Secure Credential Storage: No standardized way to store credentials locally without exposing them in plaintext or insecure configurations.
2. Limited Credential Sources: Inability to leverage common secure storage mechanisms like OS keyrings or environment variables for automated testing/CI.
3. Risk of Credential Leakage: Without a dedicated manager, there was a risk of credentials being inadvertently passed to LLMs, written to logs, or stored insecurely.
4. Absence of a Fallback Mechanism: No robust encrypted fallback for environments where OS keyrings are unavailable or undesirable.
5. Inadequate Input Validation: Potential for malformed environment variables or vault data to cause runtime errors or security vulnerabilities.
6. Non-Deterministic Testing: Credential-related tests could be flaky due to reliance on host OS keyring state.

3. Step-by-Step Technical Solution

This PR introduces the CredentialManager class, which orchestrates credential resolution and storage through a well-defined priority hierarchy and secure mechanisms:

1. Credential Resolution Hierarchy: The get_credentials method implements a strict lookup order:
   • First, it checks an in-process memory cache (_memory_cache) for programmatically injected credentials (e.g., for testing).
   • Second, it attempts to parse credentials from the TRACEPASS_CREDS environment variable, which expects a JSON string mapping domains to username/password dictionaries.
   • Third, if available, it queries the OS Keyring using a dedicated KEYRING_SERVICE_NAME (tracepass).
   • Finally, it attempts to decrypt and read credentials from a local AES-256-GCM encrypted vault file (~/.tracepass/credentials.enc), requiring a master_password.
2. Secure Encrypted Vault:
   • The save_to_encrypted_vault method encrypts credentials using AES-256-GCM. It derives a 256-bit encryption key from the master_password and a unique 16-byte salt using PBKDF2HMAC with 600,000 iterations (a strong KDF). A fresh 12-byte nonce is generated for each encryption operation.
   • The encrypted data, along with the salt, nonce, and tag, are stored in a JSON format on disk, adhering to the "Decision 4" specification.
   • Vault writes are atomic, utilizing tempfile.NamedTemporaryFile and os.replace to prevent data corruption during write operations.
   • Directory permissions are strictly enforced: 0o700 (rwx------) for the ~/.tracepass/ directory and 0o600 (rw-------) for the temporary vault file (on non-Windows systems) to restrict access.
3. Robust Input Validation and Error Handling:
   • The TRACEPASS_CREDS environment variable parsing includes explicit checks to ensure the value is a JSON dictionary, keys are strings, values are dictionaries, and username/password entries are valid strings. Malformed entries are safely skipped.
   • The read_encrypted_vault method performs extensive validation on the vault's on-disk JSON structure, checking for correct version, hex encoding, and expected byte lengths for salt, nonce, and tag. It also validates that the decrypted payload is a JSON object.
   • Custom exceptions (CredentialNotFound, DecryptionError, InvalidVaultFormat) provide clear feedback on specific failure modes.
4. Domain Normalization: A static method normalize_domain ensures consistent domain representation by stripping schemes, paths, and ports, facilitating reliable credential lookup.
5. Dependency Management: The keyring library is added as a dependency to enable OS keyring integration, with a graceful fallback if it's not installed or fails.
6. Comprehensive Testing: A new test file tests/test_credential_manager.py provides extensive coverage for all aspects of the credential manager, including domain normalization, environment variable parsing (both valid and malformed), encrypted vault save/read cycles, and various error conditions (wrong password, corrupted data, invalid format). Keyring-dependent tests are isolated using monkeypatch to ensure determinism.

4. File-by-File Breakdown & Key Implementation Details

File	Action	Purpose & Key Implementation Details
core/credential_manager.py	Added	CredentialManager Class: This new file introduces the core CredentialManager class, responsible for resolving and securely storing credentials. It defines custom exceptions (CredentialNotFound, DecryptionError, InvalidVaultFormat), constants for vault path, keyring service name, and PBKDF2 iterations, and implements the multi-source credential lookup logic (memory, env, keyring, encrypted vault) with robust validation and error handling. Encryption/Decryption Logic: Implements AES-256-GCM encryption/decryption for the local vault, using PBKDF2HMAC for key derivation with a master password, and ensuring atomic file writes with strict permissions (0o700 for directory, 0o600 for files) for enhanced security.
pyproject.toml	Modified	Dependency Addition: Adds keyring>=25.7.0 to the project's dependencies list and [package.metadata] requires-dist section. This makes the OS keyring integration an official part of the project's requirements, allowing the CredentialManager to leverage native OS credential stores.
tests/test_credential_manager.py	Added	Comprehensive Test Suite: This new file provides dedicated unit tests for the CredentialManager. It covers test_domain_normalization, test_env_injected_credentials (including malformed cases), test_encrypted_vault_save_and_read (verifying on-disk format and roundtrip), and tests for various error conditions like test_encrypted_vault_wrong_password_raises, test_encrypted_vault_corrupted_data_raises, and test_encrypted_vault_invalid_format_raises. Test Isolation: Crucially, it uses monkeypatch to isolate tests from the host OS keyring state, ensuring deterministic and reliable CI runs, as highlighted in the PR description.
uv.lock	Modified	Dependency Lock Update: This file is automatically updated by uv (the package manager) to reflect the new keyring dependency and all its transitive dependencies (e.g., jaraco-classes, jaraco-context, jaraco-functools, jeepney, pywin32-ctypes, secretstorage, more-itertools). This ensures reproducible builds across environments.

5. Architecture, Reliability & Security Considerations

• Architecture & Maintainability:

  • Modularity: The CredentialManager is a self-contained component, adhering to the "Component B" specification, which promotes clear separation of concerns.
  • Extensibility: The prioritized lookup mechanism allows for easy addition of new credential sources in the future (e.g., cloud secrets managers) by simply inserting them into the get_credentials logic.
  • Readability: The code is well-commented, and the use of custom exceptions improves error clarity and maintainability.
  • Graceful Degradation: The keyring import is wrapped in a try-except block, allowing the application to function even if the keyring library is not installed or fails, falling back to other credential sources.

• Security & Secrets:

  • No Plaintext Storage/Logging: Credentials are never stored in plaintext on disk (except temporarily in memory during processing) or logged, significantly reducing the risk of exposure.
  • Strong Cryptography: AES-256-GCM is a robust authenticated encryption algorithm, ensuring both confidentiality and integrity of the vault data.
  • Key Derivation Function: PBKDF2HMAC with 600,000 iterations provides strong protection against brute-force attacks on the master password.
  • Unique Cryptographic Primitives: Fresh salt and nonce are generated for each vault write, preventing reuse and enhancing security.
  • Atomic Writes: Using tempfile.NamedTemporaryFile and os.replace ensures that the vault file is never in a corrupted or incomplete state on disk, which is crucial for data integrity.
  • Strict File Permissions: Enforcing 0o700 for the parent directory and 0o600 for the vault file (on non-Windows) restricts access to the owner only, preventing unauthorized reading or modification.
  • Input Validation: Extensive validation for TRACEPASS_CREDS and vault data format prevents parsing errors and potential injection vulnerabilities.

• Performance:

  • Memory Cache: The in-process memory cache provides the fastest lookup for frequently accessed credentials.
  • Keyring/Env Var: Accessing environment variables and OS keyrings is generally fast.
  • Encrypted Vault: Decryption involves PBKDF2HMAC, which is intentionally computationally intensive to deter brute-force attacks. While this adds a slight overhead, it's a necessary security trade-off and should only occur once per application run (or when the master password is provided) to load the vault into memory. Subsequent lookups from the vault will be fast.
  • Atomic Writes: The atomic write mechanism might involve a slight overhead due to temporary file creation and renaming, but it's negligible for typical credential management operations.

6. Risk Assessment & Edge Cases

• Overall Risk Level: 🟢 Low

  • The implementation is well-tested, follows secure coding practices, and addresses previous review feedback. The use of standard cryptographic primitives and atomic file operations minimizes common risks.

• Potential Edge Cases / Side Effects:

  • Master Password Management: The master_password is passed directly to the CredentialManager constructor and save_to_encrypted_vault. While this is necessary for decryption/encryption, its secure handling outside the CredentialManager (e.g., how it's obtained from the user or another secure source) is critical and falls outside the scope of this PR. If the master password is lost, the encrypted vault becomes unrecoverable.
  • Keyring Availability: The keyring library might have platform-specific issues or require additional system dependencies (e.g., secret-service on Linux). The graceful fallback to None handles the library import, but runtime errors from keyring itself could still occur, though they are suppressed with contextlib.suppress(Exception).
  • Concurrent Vault Access: While atomic writes protect against corruption during a single write, multiple concurrent processes attempting to write to the same vault file could lead to race conditions where one write overwerites another's changes if not properly coordinated at a higher level. This PR assumes single-process or serialized access for vault modifications.
  • TRACEPASS_CREDS Size: If TRACEPASS_CREDS contains an extremely large number of credentials, parsing it on every get_credentials call could introduce minor overhead. However, this is unlikely for typical use cases.

7. Reviewer & Testing Verification Checklist

• Verify that core/credential_manager.py adheres to the "Decision 4" specification for the encrypted vault format (version, salt/nonce/tag lengths, JSON object payload).
• Confirm that the get_credentials method correctly prioritizes credential sources: in-memory > TRACEPASS_CREDS > OS Keyring > Encrypted Vault.
• Manually test TRACEPASS_CREDS with both valid and intentionally malformed JSON to ensure robust parsing and error handling (malformed entries are skipped, valid ones are retrieved).
• If possible, test the OS Keyring integration on different operating systems (Windows, macOS, Linux) to ensure keyring functions as expected, or at least confirm the graceful fallback if keyring is not installed.
• Verify that the save_to_encrypted_vault method creates the ~/.tracepass/ directory with 0o700 permissions and the vault file with 0o600 permissions (on non-Windows systems).
• Run pytest -v to confirm all 75 tests pass, specifically focusing on tests/test_credential_manager.py to ensure all new credential management scenarios are covered.
• Review the uv.lock file to ensure keyring and its dependencies are correctly added and locked.
• Confirm that no plaintext credentials appear in logs or temporary files during the save/read operations of the encrypted vault.
