import "crypto/sha1"
Package sha1 implements the SHA-1 hash algorithm as defined in RFC 3174.
SHA-1 is cryptographically broken and should not be used for secure applications.
sha1.go sha1block.go sha1block_amd64.go
const BlockSize = 64
The blocksize of SHA-1 in bytes.
const Size = 20
The size of a SHA-1 checksum in bytes.
New returns a new hash.Hash computing the SHA1 checksum. The Hash also implements encoding.BinaryMarshaler and encoding.BinaryUnmarshaler to marshal and unmarshal the internal state of the hash.
Code:play
h := sha1.New() io.WriteString(h, "His money is twice tainted:") io.WriteString(h, " 'taint yours and 'taint mine.") fmt.Printf("% x", h.Sum(nil))
Output:
59 7f 6a 54 00 10 f9 4c 15 d7 18 06 a9 9a 2c 87 10 e7 47 bd
Code:play
f, err := os.Open("file.txt") if err != nil { log.Fatal(err) } defer f.Close() h := sha1.New() if _, err := io.Copy(h, f); err != nil { log.Fatal(err) } fmt.Printf("% x", h.Sum(nil))
Sum returns the SHA-1 checksum of the data.
