Module sequoia_openpgp::crypto::hash

Cryptographic hash functions and hashing of OpenPGP data structures.

This module provides trait Digest representing a hash function context independent of the cryptographic backend, as well as trait Hash that handles hashing of OpenPGP data structures.

Examples

use sequoia_openpgp::types::HashAlgorithm;

// Create a context and feed data to it.
let mut ctx = HashAlgorithm::SHA512.context()?;
ctx.update(&b"The quick brown fox jumps over the lazy dog."[..]);

// Extract the digest.
let mut digest = vec![0; ctx.digest_size()];
ctx.digest(&mut digest);

use sequoia_openpgp::fmt::hex;
assert_eq!(&hex::encode(digest),
           "91EA1245F20D46AE9A037A989F54F1F7\
            90F0A47607EEB8A14D12890CEA77A1BB\
            C6C7ED9CF205E67B7F2B8FD4C7DFD3A7\
            A8617E45F3C463D481C7E586C39AC1ED");
