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.
func ShareKey ¶
func ShareKey(privateKey PrivateKey, publicKey PublicKey) []byte
ShareKey curve25519
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.
Types ¶
type PrivateKey ¶
type PrivateKey []byte
PrivateKey is the type of Ed25519 private keys. It implements crypto.Signer.
func ConvertPrivateKey ¶
func ConvertPrivateKey(privateKey PrivateKey) PrivateKey
ConvertPrivateKey Converts Ed25519 secret key to Curve25519 secret key.
func NewKeyFromSeed ¶
func NewKeyFromSeed(seed []byte) PrivateKey
NewKeyFromSeed calculates a private key from a seed. It will panic if len(seed) is not SeedSize. This function is provided for interoperability with RFC 8032. RFC 8032's private keys correspond to seeds in this package.
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 8032. RFC 8032's private keys correspond to seeds in this package.
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.
