import "crypto/sha256"

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

Go 1.26.1

Constants

const BlockSize = 64

The blocksize of SHA256 and SHA224 in bytes.

crypto/sha256/sha256.go:28

const Size = 32

The size of a SHA256 checksum in bytes.

crypto/sha256/sha256.go:22

const Size224 = 28

The size of a SHA224 checksum in bytes.

crypto/sha256/sha256.go:25

Functions

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.

crypto/sha256/sha256.go:34

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(data []byte) [Size224]byte

Sum224 returns the SHA224 checksum of the data.

crypto/sha256/sha256.go:65

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

Sum256 returns the SHA256 checksum of the data.
