keychain-secure

What problem does it solve?

This Skill provides secure credential storage on macOS with GF(3) balance, ensuring a credential's lifecycle (store, retrieve, validate) maintains invariants and avoids leaking secrets via environment variables.

Core Features & Use Cases

• Secure storage: Encrypted credentials in macOS Keychain
• GF(3) balance: Balanced lifecycle across store, transport, and validate
• Cross-language examples: Python and Ruby APIs for managing credentials
• Use Case: Store an API key securely, retrieve when needed, and rotate safely

Quick Start

Store a credential with security add-generic-password -s "service" -a "$USER" -w "secret" -U, then retrieve with security find-generic-password -s "service" -a "$USER" -w and validate it matches the stored value.
