Pqvault

This is a secrets manager built specifically for AI agents with post-quantum cryptographic primitives. It uses ML-KEM-768 (the NIST-standardized lattice-based key encapsulation mechanism) alongside X25519 for hybrid encryption and AES-256-GCM for the actual secret storage. You'd reach for this if you're building agents that need to handle API keys, credentials, or sensitive configuration data and want protection against future quantum attacks. The hybrid approach means you get both traditional elliptic curve security today and quantum resistance tomorrow. Implementation is in Rust, so expect solid memory safety guarantees around your cryptographic operations.
