Documentation

Overview

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.

Index

• Constants
• func New() hash.Hash
• func SetState(h hash.Hash, state [5]uint32)
• func Sum(data []byte) [Size]byte

Constants

const BlockSize = 64

The blocksize of SHA-1 in bytes.

const Size = 20

The size of a SHA-1 checksum in bytes.

Functions

func New

func New() hash.Hash

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.

func SetState

func SetState(h hash.Hash, state [5]uint32)

SetState sets h to the supplied state to enable MAC length-extension attacks. h must have been returned by an earlier call to this package's New() function.

func Sum

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

Sum returns the SHA-1 checksum of the data.
