def SZ224: size = 28;

The size, in bytes, of a SHA-512/224 checksum.

def SZ256[permalink] [source]

def SZ256: size = 32;

Functions

fn sha384[permalink] [source]

fn sha384() digest;

Creates a hash::hash which computes a SHA-384 hash. If this function is used to hash sensitive information, the caller should call hash::close to erase sensitive data from memory after use; if not, the use of hash::close is optional.

fn sha512[permalink] [source]

fn sha512() digest;

Creates a hash::hash which computes a SHA-512 hash. If this function is used to hash sensitive information, the caller should call hash::close to erase sensitive data from memory after use; if not, the use of hash::close is optional.

fn sha512_224[permalink] [source]

fn sha512_224() digest;

Creates a hash::hash which computes a SHA-512/224 hash. If this function is used to hash sensitive information, the caller should call hash::close to erase sensitive data from memory after use; if not, the use of hash::close is optional.

fn sha512_256[permalink] [source]

fn sha512_256() digest;

Creates a hash::hash which computes a SHA-512/256 hash. If this function is used to hash sensitive information, the caller should call hash::close to erase sensitive data from memory after use; if not, the use of hash::close is optional.
