Overview

Package crypto collects common cryptographic constants.

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
	MD5
	SHA1
	SHA224
	SHA256
	SHA384
	SHA512
	MD5SHA1
	RIPEMD160
	SHA3_224
	SHA3_256
	SHA3_384
	SHA3_512
)

func (Hash) Available 

func (h Hash) Available() bool

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

func (Hash) HashFunc added in v1.4.0 

func (h Hash) HashFunc() Hash

HashFunc simply returns the value of h so that Hash implements SignerOpts.

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 added in v1.2.0 

type PublicKey interface{}

PublicKey represents a public key using an unspecified algorithm.

type Signer added in v1.4.0 

type Signer interface {
	Public() PublicKey

	Sign(rand io.Reader, msg []byte, opts SignerOpts) (signature []byte, err error)
}

Signer is an interface for an opaque private key that can be used for signing operations. For example, an RSA key kept in a hardware module.

type SignerOpts added in v1.4.0 

type SignerOpts interface {
	HashFunc() Hash
}

SignerOpts contains options for signing with a Signer.
