//! # mytheclipse-crypto
|
|
//!
|
|
//! Low-level security helpers that are easy to get wrong when hand-rolled:
|
|
//!
|
|
//! - **Argon2id** password hashing & verification (`password` feature), with
|
|
//! RFC 9106-ish parameters.
|
|
//! - **AES-256-GCM** authenticated encryption with a fresh random nonce per
|
|
//! operation (`encryption` feature).
|
|
//! - **JWT** (HS256) / **Paseto** v4 local token generation & validation (`tokens`
|
|
//! feature).
|
|
//! - **Key rotation** via [`KeyRing`]: decryption/verification tries the current
|
|
//! key then a list of previous keys.
|
|
//!
|
|
//! Nothing in the crate owns long-lived key material; keys are passed in as
|
|
//! bytes/keys by the caller and the caller is responsible for storage. Each
|
|
//! primitive is small enough to reason about in one screen.
|
|
//!
|
|
//! ## Example
|
|
//!
|
|
//! ```no_run
|
|
//! use mytheclipse_crypto::{PasswordHasher, Encryptor, TokenSigner};
|
|
//!
|
|
//! // Hash & verify a password.
|
|
//! let hasher = PasswordHasher::new();
|
|
//! let hash = hasher.hash("hunter2").unwrap();
|
|
//! assert!(hasher.verify(&hash, "hunter2"));
|
|
//!
|
|
//! // Encrypt & decrypt a blob.
|
|
//! let key = [0u8; 32];
|
|
//! let enc = Encryptor::new(&key);
|
|
//! let (nonce, ct) = enc.encrypt(b"secret message");
|
|
//! let plain = enc.decrypt(&nonce, &ct).unwrap();
|
|
//! assert_eq!(plain, b"secret message");
|
|
//!
|
|
//! // Sign & verify a JWT.
|
|
//! let signer = TokenSigner::new("super-secret-key");
|
|
//! let token = signer
|
|
//! .sign(&serde_json::json!({ "sub": "u1" }), std::time::Duration::from_secs(3600))
|
|
//! .unwrap();
|
|
//! let claims = signer.verify(&token).unwrap();
|
|
//! assert_eq!(claims["sub"], "u1");
|
|
//! ```
