Package sha256
Package sha256 implements the SHA224 and SHA256 hash algorithms as defined
in FIPS 180-4.
In the call graph viewer below, each node
is a function belonging to this package
and its children are the functions it
calls—perhaps dynamically.
The root nodes are the entry points of the
package: functions that may be called from
outside the package.
There may be non-exported or anonymous
functions among them if they are called
dynamically from another package.
Click a node to visit that function's source code.
From there you can visit its callers by
clicking its declaring func
token.
Functions may be omitted if they were
determined to be unreachable in the
particular programs or tests that were
analyzed.
Constants
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.
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 [Size224]byte)
Sum224 returns the SHA224 checksum of the data.
func Sum256(data []byte) [Size]byte
Sum256 returns the SHA256 checksum of the data.
