Overview ▾

Package crypto collects common cryptographic constants.

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.

type Hash

type Hash uint

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

const (
        MD4       Hash = 1 + iota // import code.google.com/p/go.crypto/md4
        MD5                       // import crypto/md5
        SHA1                      // import crypto/sha1
        SHA224                    // import crypto/sha256
        SHA256                    // import crypto/sha256
        SHA384                    // import crypto/sha512
        SHA512                    // import crypto/sha512
        MD5SHA1                   // no implementation; MD5+SHA1 used for TLS RSA
        RIPEMD160                 // import code.google.com/p/go.crypto/ripemd160

)

func (Hash) Available

func (h Hash) Available() bool

Available reports whether the given hash function is linked into the binary.

func (Hash) New

func (h Hash) New() hash.Hash

New returns a new hash.Hash calculating the given hash function. New panics if the hash function is not linked into the binary.

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.

type PrivateKey

type PrivateKey interface{}

PrivateKey represents a private key using an unspecified algorithm.

type PublicKey

type PublicKey interface{}

PublicKey represents a public key using an unspecified algorithm.
