Constants ¶
const ( // PublicKeySize is the size, in bytes, of public keys as used in this package. PublicKeySize = 32 // PrivateKeySize is the size, in bytes, of private keys as used in this package. PrivateKeySize = PrivateKeyFormSize + PublicKeySize PrivateKeyFormSize = 64 // SignatureSize is the size, in bytes, of signatures generated and verified by this package. SignatureSize = 64 )

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 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
func NewKeyFromRaw ¶
func NewKeyFromRaw(h []byte) PrivateKey
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 NewKeyFromStandard ¶
func NewKeyFromStandard(key goEd25519.PrivateKey) PrivateKey
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) 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.
