-//! Message signatures.
-//!
-//! The `Signer` allows for the computation of cryptographic signatures of
-//! data given a private key. The `Verifier` can then be used with the
-//! corresponding public key to verify the integrity and authenticity of that
-//! data given the signature.
-//!
-//! # Examples
-//!
-//! Sign and verify data given an RSA keypair:
-//!
-//! ```rust
-//! use openssl::crypto::sign::{Signer, Verifier};
-//! use openssl::crypto::rsa::RSA;
-//! use openssl::crypto::pkey::PKey;
-//! use openssl::crypto::hash::MessageDigest;
-//!
-//! // Generate a keypair
-//! let keypair = RSA::generate(2048).unwrap();
-//! let keypair = PKey::from_rsa(keypair).unwrap();
-//!
-//! let data = b"hello, world!";
-//! let data2 = b"hola, mundo!";
-//!
-//! // Sign the data
-//! let mut signer = Signer::new(MessageDigest::sha256(), &keypair).unwrap();
-//! signer.update(data).unwrap();
-//! signer.update(data2).unwrap();
-//! let signature = signer.finish().unwrap();
-//!
-//! // Verify the data
-//! let mut verifier = Verifier::new(MessageDigest::sha256(), &keypair).unwrap();
-//! verifier.update(data).unwrap();
-//! verifier.update(data2).unwrap();
-//! assert!(verifier.finish(&signature).unwrap());
-//! ```
-//!
-//! Compute an HMAC (note that `Verifier` cannot be used with HMACs):
-//!
-//! ```rust
-//! use openssl::crypto::sign::Signer;
-//! use openssl::crypto::pkey::PKey;
-//! use openssl::crypto::hash::MessageDigest;
-//!
-//! // Create a PKey
-//! let key = PKey::hmac(b"my secret").unwrap();
-//!
-//! let data = b"hello, world!";
-//! let data2 = b"hola, mundo!";
-//!
-//! // Compute the HMAC
-//! let mut signer = Signer::new(MessageDigest::sha256(), &key).unwrap();
-//! signer.update(data).unwrap();
-//! signer.update(data2).unwrap();
-//! let hmac = signer.finish().unwrap();
-//! ```
