Functions

func RegisterHash 

func RegisterHash(h Hash, f func() hash.Hash)

RegisterHash registers a function that returns a new instance of the given hash function. This is intended to be called from the init function in packages that implement hash functions.

Types

type Hash 

type Hash uint

Hash identifies a cryptographic hash function that is implemented in another package. 

const (
	MD4       Hash = 1 + iota // in package crypto/md4
	MD5                       // in package crypto/md5
	SHA1                      // in package crypto/sha1
	SHA224                    // in package crypto/sha256
	SHA256                    // in package crypto/sha256
	SHA384                    // in package crypto/sha512
	SHA512                    // in package crypto/sha512
	MD5SHA1                   // no implementation; MD5+SHA1 used for TLS RSA
	RIPEMD160                 // in package crypto/ripemd160

)

func (Hash) New 

func (h Hash) New() hash.Hash

New returns a new hash.Hash calculating the given hash function. If the hash function is not linked into the binary, New returns nil.

func (Hash) Size 

func (h Hash) Size() int

Size returns the length, in bytes, of a digest resulting from the given hash function. It doesn't require that the hash function in question be linked into the program.
