Constants
The blocksize of SHA256 and SHA224 in bytes.
const BlockSize = 64The size of a SHA256 checksum in bytes.
const Size = 32The size of a SHA224 checksum in bytes.
const Size224 = 28func New
func New() hash.HashNew returns a new hash.Hash computing the SHA256 checksum. The Hash also implements encoding.BinaryMarshaler and encoding.BinaryUnmarshaler to marshal and unmarshal the internal state of the hash.
