Crate egide_crypto 

Egide Crypto

Core cryptographic primitives for Egide.

This crate provides low-level cryptographic operations including:

• Symmetric encryption (AES-256-GCM)
• Key derivation (HKDF-SHA256)
• Secure random generation (OS CSPRNG)
• Memory-safe key types with automatic zeroization

Security

All sensitive key material is automatically zeroized when dropped. Keys implement Debug with redacted output to prevent accidental logging.

Example

use egide_crypto::{aead, keys::SymmetricKey};

// Generate a key and encrypt some data
let key = SymmetricKey::generate().unwrap();
let plaintext = b"secret message";

let ciphertext = aead::encrypt(key.as_bytes(), plaintext, None).unwrap();
let decrypted = aead::decrypt(key.as_bytes(), &ciphertext, None).unwrap();

assert_eq!(&*decrypted, plaintext);
