| //! |
| //! 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::sign::{Signer, Verifier}; |
| //! use openssl::rsa::Rsa; |
| //! use openssl::pkey::PKey; |
| //! use openssl::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.sign_to_vec().unwrap(); |
| //! |
| //! // Verify the data |
| //! let mut verifier = Verifier::new(MessageDigest::sha256(), &keypair).unwrap(); |
| //! verifier.update(data).unwrap(); |
| //! verifier.update(data2).unwrap(); |
| //! assert!(verifier.verify(&signature).unwrap()); |
| //! ``` |

| Compute an HMAC: |

| |
