About

encrypt-api-keys

This skill covers AES-256-GCM encryption for provider API keys.

Trigger: Load this skill when handling crypto operations for API keys.

Quick Reference

| Task | Pattern | |------|---------| | Derive user key | derive_user_key | | Encrypt API key | encrypt_key |

Critical Patterns (Summary)

  • Derive User Key: Generate a secure key for user-specific encryption.
  • Encrypt API Key: Securely encrypt an API key using AES-256-GCM.

Critical Patterns (Detailed)

Derive User Key

Generate a secure key for user-specific encryption using the derive_user_key function.

from apps.server.app.services.crypto import derive_user_key

user_key = derive_user_key(user_id="example_user")

Encrypt API Key

Securely encrypt an API key using AES-256-GCM with the encrypt_key function.

from apps.server.app.services.crypto import encrypt_key

encrypted_key = encrypt_key(api_key="my_secret_api_key", user_key=user_key)

When to Use

  • When you need to securely store API keys for different providers.
  • When encrypting sensitive information before transmission.

Commands

docker-compose run app python apps/server/app/main.py

Anti-Patterns

Don't: Hardcode API Keys

Hardcoding API keys in the source code exposes them to security risks.

# BAD
api_key = "my_secret_api_key"
