LLM Config Manager

Enterprise-grade configuration management for LLM applications

Overview

LLM Config Manager is a production-ready, enterprise-grade configuration management system purpose-built for Large Language Model (LLM) applications. It provides secure, scalable, and efficient configuration management with built-in support for multiple environments, encryption, versioning, caching, role-based access control, and comprehensive security features.

Why LLM Config Manager?

Managing configurations for LLM applications is complex:

Security: API keys and secrets need military-grade encryption
Environments: Different settings for dev, staging, and production
Versioning: Track configuration changes and rollback when needed
Performance: Fast access to configs without sacrificing security
Compliance: Meet SOC 2, ISO 27001, GDPR, HIPAA, and PCI DSS requirements

LLM Config Manager solves these challenges with an elegant, production-tested solution.

await init();

// Use RBAC
const manager = rbac.RBACManager.new();
manager.create_role('admin', ['read', 'write', 'delete']);
manager.assign_role('user123', 'admin', 'production');

if (manager.can_write('user123', 'config.key', 'production')) {
  console.log('User has write permission');
}

TypeScript Support:

import init, * as crypto from '@llm-dev-ops/llm-config-crypto';

async function encrypt(data: Uint8Array, key: Uint8Array): Promise<Uint8Array> {
  await init();
  return crypto.encrypt(data, key);
}

    )?;

    // Set secret (encrypted)
    manager.set_secret(

        "api_key",
        b"sk-proj-...",
        Environment::Production,
        "admin",
    )?;

    // Get configuration
    if let Some(entry) = manager.get("app/llm", "model", Environment::Production)? {
        println!("Model: {:?}", entry.value);
