//! Secret-key One-time authentication
//!
//! # Security model
//! The `authenticate()` function, viewed as a function
//! of the message for a uniform random key, is designed to meet the
//! standard notion of unforgeability after a single message. After the
//! sender authenticates one message, an attacker cannot find authenticators
//! for any other messages.
//!
//! The sender must not use `authenticate()` to authenticate more than one message
//! under the same key. Authenticators for two messages under the same key should
//! be expected to reveal enough information to allow forgeries of authenticators
//! on other messages.
//!
//! # Selected primitive
//! `authenticate()` is `crypto_onetimeauth_poly1305`, an authenticator specified
//! in [Cryptography in NaCl](http://nacl.cr.yp.to/valid.html), Section 9. This
//! authenticator is proven to meet the standard notion of unforgeability after a
//! single message.
//!
//! # Example
//! ```
//! use sodiumoxide::crypto::onetimeauth;
//!
//! let key = onetimeauth::gen_key();
//! let data_to_authenticate = b"some data";
//! let tag = onetimeauth::authenticate(data_to_authenticate, &key);
//! assert!(onetimeauth::verify(&tag, data_to_authenticate, &key));
//! ```
