astrid-crypto 0.5.0

//! Astrid Crypto - Cryptographic primitives for the secure agent runtime.
//!
//! This crate provides:
//! - Ed25519 key pairs with secure memory handling
//! - Signatures for capability tokens and audit entries
//! - BLAKE3 content hashing for audit chains and verification
//!
//! # Security Philosophy
//!
//! **Cryptography over prompts.** Authorization comes from ed25519 signatures
//! and capability tokens, not from hoping the LLM follows instructions.
//!
//! # Example
//!
//! ```
//! use astrid_crypto::{KeyPair, ContentHash};
//!
//! // Generate a new key pair
//! let keypair = KeyPair::generate();
//!
//! // Sign a message
//! let message = b"important data";
//! let signature = keypair.sign(message);
//!
//! // Verify the signature
//! assert!(keypair.verify(message, &signature).is_ok());
//!
//! // Hash content
//! let hash = ContentHash::hash(message);
//! println!("Hash: {}", hash.to_hex());
//! ```
