Struct sha2_const::Sha512_256

pub struct Sha512_256 { /* fields omitted */ }

The SHA-512/256 hash function.

The SHA-512 algorithm with the SHA-512/256 initialization vector, truncated to 256 bits.

Examples

const DIGEST: [u8; 32] = Sha512_256::new()
    .update(b"The quick brown fox ")
    .update(b"jumps over the lazy dog")
    .finalize();

assert_eq!(
    hex::encode(&DIGEST[..]),
    "dd9d67b371519c339ed8dbd25af90e976a1eeefd4ad3d889005e532fc5bef04d"
);
