          Functions

          func New

          func New() hash.Hash

            New 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.

            Example
            Output:

            func New224

            func New224() hash.Hash

              New224 returns a new hash.Hash computing the SHA224 checksum.

              func Sum224

              func Sum224(data []byte) (sum224 [Size224]byte)

                Sum224 returns the SHA224 checksum of the data.

                func Sum256

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

                  Sum256 returns the SHA256 checksum of the data.

                  Example
                  Output:
