Functions

func GenerateKey

func GenerateKey(rand io.Reader) (PublicKey, PrivateKey, error)

GenerateKey generates a public/private key pair using entropy from rand. If rand is nil, crypto/rand.Reader will be used.

Types

type PrivateKey

type PrivateKey []byte

PrivateKey is the type of X25519 private key

func NewKeyFromSeed

func NewKeyFromSeed(seed []byte) (PrivateKey, error)

NewKeyFromSeed calculates a private key from a seed. It will return an error if len(seed) is not SeedSize. This function is provided for interoperability with RFC 7748. RFC 7748's private keys correspond to seeds in this package.

func (PrivateKey) Equal

func (priv PrivateKey) Equal(x crypto.PrivateKey) bool

Equal reports whether priv and x have the same value.

func (PrivateKey) Public

func (priv PrivateKey) Public() crypto.PublicKey

Public returns the PublicKey corresponding to priv.

func (PrivateKey) Seed

func (priv PrivateKey) Seed() []byte

Seed returns the private key seed corresponding to priv. It is provided for interoperability with RFC 7748. RFC 7748's private keys correspond to seeds in this package.

type PublicKey

type PublicKey []byte

PublicKey is the type of X25519 public keys

func (PublicKey) Equal

func (pub PublicKey) Equal(x crypto.PublicKey) bool

Equal reports whether pub and x have the same value.
