Variables ¶
var RandFail = eofReader{}
RandFail is a Reader that doesn't deliver any data
var RandReader = rand.Reader
RandReader defines the CSPRNG used in Mute.
var RandZero = zeroReader{}
RandZero is a Reader that always returns 0.
Functions ¶
func CKDF ¶
CKDF (Cheap Key Derivation Function) generates two keys k1 and k2 from the given nonce. Specification: https://github.com/mutecomm/mute/blob/master/doc/ciphers.md#ckdf-cheap-key-derivation-function
func ECDH ¶
ECDH computes a Diffie-Hellman (DH) key exchange over the elliptic curve (EC) curve25519. If ownPublicKey is given it is used to check for the key reflection attack. Otherwise it is derived from privateKey.
Types ¶
type Curve25519Key ¶
type Curve25519Key struct {
// contains filtered or unexported fields
}
Curve25519Key holds a Curve25519 key pair.
func Curve25519Generate ¶
func Curve25519Generate(rand io.Reader) (*Curve25519Key, error)
Curve25519Generate generates a new Curve25519 key pair.
func (*Curve25519Key) PrivateKey ¶
func (c *Curve25519Key) PrivateKey() *[32]byte
PrivateKey returns the private key of an curve25519Key.
func (*Curve25519Key) PublicKey ¶
func (c *Curve25519Key) PublicKey() *[32]byte
