Overview ▾

Package sha256 implements the SHA224 and SHA256 hash algorithms as defined in FIPS 180-4.

Constants

The blocksize of SHA256 and SHA224 in bytes.

const BlockSize = 64

The size of a SHA256 checksum in bytes.

const Size = 32

The size of a SHA224 checksum in bytes.

const Size224 = 28

func New

func New() hash.Hash

New returns a new hash.Hash computing the SHA256 checksum. The Hash also implements encoding.BinaryMarshaler, encoding.BinaryAppender and encoding.BinaryUnmarshaler to marshal and unmarshal the internal state of the hash.

Example

Example (File)

func New224

func New224() hash.Hash

New224 returns a new hash.Hash computing the SHA224 checksum. The Hash also implements encoding.BinaryMarshaler, encoding.BinaryAppender and encoding.BinaryUnmarshaler to marshal and unmarshal the internal state of the hash.

func Sum224 1.2

func Sum224(data []byte) [Size224]byte

Sum224 returns the SHA224 checksum of the data.

func Sum256 1.2

func Sum256(data []byte) [Size]byte

Sum256 returns the SHA256 checksum of the data.
