Package-Level Functions (total 12, in which 4 are exported)

	 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.

	 func New224() hash.Hash
		New224 returns a new hash.Hash computing the SHA224 checksum.

	 func Sum224(data []byte) (sum224 [28]byte)
		Sum224 returns the SHA224 checksum of the data.

	 func Sum256(data []byte) [32]byte
		Sum256 returns the SHA256 checksum of the data.

	/* 8 unexporteds ... *//* 8 unexporteds: */
	 func appendUint32(b []byte, x uint32) []byte
	 func appendUint64(b []byte, x uint64) []byte
	 func block(dig *digest, p []byte)
	 func blockGeneric(dig *digest, p []byte)
	 func consumeUint32(b []byte) ([]byte, uint32)
	 func consumeUint64(b []byte) ([]byte, uint64)
	 func init()
	 func sha256block(h []uint32, p []byte, k []uint32)

Package-Level Constants (total 23, in which 3 are exported)

	const BlockSize = 64
		The blocksize of SHA256 and SHA224 in bytes.

	const Size = 32
		The size of a SHA256 checksum in bytes.

	const Size224 = 28
		The size of a SHA224 checksum in bytes.
