Overview

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

Examples

New

New (File)

Sum256

Package files

sha256.go sha256block.go sha256block_amd64.go sha256block_decl.go

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 and encoding.BinaryUnmarshaler to marshal and unmarshal the internal state of the hash.

Example -

Code:

h := sha256.New()
-h.Write([]byte("hello world\n"))
-fmt.Printf("%x", h.Sum(nil))
-

Output:

a948904f2f0f479b8f8197694b30184b0d2ed1c1cd2a1ec0fb85d299a192a447
-

Example (File) -

Code:

-f, err := os.Open("file.txt")
-if err != nil {
-    log.Fatal(err)
-}
-defer f.Close()
-
-h := sha256.New()
-if _, err := io.Copy(h, f); err != nil {
-    log.Fatal(err)
-}
-
-fmt.Printf("%x", h.Sum(nil))
-

func New224

func New224() hash.Hash

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

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.

Example -

Code:

sum := sha256.Sum256([]byte("hello world\n"))
-fmt.Printf("%x", sum)
-

Output:
