Functions ¶
func AddNamedCurve ¶
func AddNamedCurve(curve elliptic.Curve, oid asn1.ObjectIdentifier)
func BatchVerify ¶
* BIP0340 batch verification functions.
func MarshalECPrivateKey ¶
func MarshalECPrivateKey(key *PrivateKey) ([]byte, error)
MarshalECPrivateKey converts an EC private key to SEC 1, ASN.1 DER form.
This kind of key is commonly encoded in PEM blocks of type "EC PRIVATE KEY". For a more flexible key format which is not EC specific, use MarshalPKCS8PrivateKey.
func MarshalPrivateKey ¶
func MarshalPrivateKey(key *PrivateKey) ([]byte, error)
Marshal PrivateKey to der
func MarshalPublicKey ¶
Marshal PublicKey to der
func NamedCurveFromOid ¶
func NamedCurveFromOid(oid asn1.ObjectIdentifier) elliptic.Curve
func OidFromNamedCurve ¶
func OidFromNamedCurve(curve elliptic.Curve) (asn1.ObjectIdentifier, bool)
func SignToRS ¶
func SignToRS(random io.Reader, priv *PrivateKey, hashFunc Hasher, msg []byte) (r, s *big.Int, err error)
* BIP0340 signature. * NOTE: because of the semi-deterministinc nonce generation * process, streaming mode is NOT supported for signing. * Hence the following all-in-one signature function.
func SignUsingKToRS ¶
func SignUsingKToRS(k *big.Int, priv *PrivateKey, hashFunc Hasher, msg []byte) (r, s *big.Int, err error)
sign with k
func Verify ¶
Verify verifies the ASN.1 encoded signature, sig, M, of hash using the public key, pub. Its return value records whether the signature is valid.
func VerifyBytes ¶
Verify verifies the Bytes encoded signature
Types ¶
type PrivateKey ¶
bip0340 PrivateKey
func GenerateKey ¶
Generate the PrivateKey
func NewPrivateKey ¶
func NewPrivateKey(curve elliptic.Curve, k []byte) (*PrivateKey, error)
New a PrivateKey from privatekey data
func ParseECPrivateKey ¶
func ParseECPrivateKey(der []byte) (*PrivateKey, error)
ParseECPrivateKey parses an EC private key in SEC 1, ASN.1 DER form.
This kind of key is commonly encoded in PEM blocks of type "EC PRIVATE KEY".
func ParsePrivateKey ¶
func ParsePrivateKey(derBytes []byte) (*PrivateKey, error)
Parse PrivateKey der
func (*PrivateKey) Equal ¶
func (priv *PrivateKey) Equal(x crypto.PrivateKey) bool
Equal reports whether pub and x have the same value.
func (*PrivateKey) Public ¶
func (priv *PrivateKey) Public() crypto.PublicKey
Public returns the public key corresponding to priv.
func (*PrivateKey) Sign ¶
func (priv *PrivateKey) Sign(rand io.Reader, digest []byte, opts crypto.SignerOpts) ([]byte, error)
crypto.Signer
type PublicKey ¶
Schnorr Signatures for secp256k1 bip0340 PublicKey
func NewPublicKey ¶
New a PublicKey from publicKey data
func ParsePublicKey ¶
Parse PublicKey der
type SignerOpts ¶
type SignerOpts struct {
Hash Hasher
}
SignerOpts contains options for creating and verifying EC-GDSA signatures.
func (*SignerOpts) GetHash ¶
func (opts *SignerOpts) GetHash() Hasher
GetHash returns func() hash.Hash
func (*SignerOpts) HashFunc ¶
func (opts *SignerOpts) HashFunc() crypto.Hash
HashFunc returns opts.Hash
