//! This crate provides methods to convert OpenSSL cipher suite names into the
//! equivalent RFC name and vice versa.
//!
//! ```
//! use openssl_to_rfc::TLSCipherSuite;
//!
//! let openssl_name = "ECDH-RSA-AES128-GCM-SHA256";
//! let cipher = TLSCipherSuite::from_openssl_name(openssl_name).unwrap();
//!
//! assert_eq!(cipher, TLSCipherSuite::TLS_ECDH_RSA_WITH_AES_128_GCM_SHA256);
//! assert_eq!(cipher.as_openssl_name(), openssl_name);
//! ```
//!
//! For SSLv2 cipher suites, use the `SSLV2CipherSuite` enum instead.
