func Sign ¶
func Sign(privateKey PrivateKey, message []byte) []byte
Sign signs the message with privateKey and returns a signature. It will panic if len(privateKey) is not PrivateKeySize.
func Verify ¶
func Verify(publicKey PublicKey, message, sig []byte) bool
Verify reports whether sig is a valid signature of message by publicKey. It will panic if len(publicKey) is not PublicKeySize.
type PrivateKey ¶
PrivateKey is the type of Ed25519 private keys. It implements crypto.Signer.
type PrivateKey []byte
func (PrivateKey) Public ¶
func (priv PrivateKey) Public() crypto.PublicKey
Public returns the PublicKey corresponding to priv.
func (PrivateKey) Sign ¶
func (priv PrivateKey) Sign(rand io.Reader, message []byte, opts crypto.SignerOpts) (signature []byte, err error)
Sign signs the given message with priv. Ed25519 performs two passes over messages to be signed and therefore cannot handle pre-hashed messages. Thus opts.HashFunc() must return zero to indicate the message hasn't been hashed. This can be achieved by passing crypto.Hash(0) as the value for opts.
type PublicKey ¶
PublicKey is the type of Ed25519 public keys.
type PublicKey []byte
func GenerateKey ¶
func GenerateKey(rand io.Reader) (publicKey PublicKey, privateKey PrivateKey, err error)
GenerateKey generates a public/private key pair using entropy from rand. If rand is nil, crypto/rand.Reader will be used.
