Functions ¶

func AddNamedCurve ¶

func AddNamedCurve(curve elliptic.Curve, oid asn1.ObjectIdentifier)

func BitsToBytes ¶

func BitsToBytes(bits int) int

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)

包装私钥

func MarshalPublicKey ¶

func MarshalPublicKey(pub *PublicKey) ([]byte, error)

包装公钥

func NamedCurveFromOid ¶

func NamedCurveFromOid(oid asn1.ObjectIdentifier) elliptic.Curve

func OidFromNamedCurve ¶

func OidFromNamedCurve(curve elliptic.Curve) (asn1.ObjectIdentifier, bool)

func Sign ¶

func Sign(rand io.Reader, priv *PrivateKey, h hash.Hash, data []byte) (sig []byte, err error)

Sign data returns the ASN.1 encoded signature.

func SignToRS ¶

func SignToRS(rand io.Reader, priv *PrivateKey, h hash.Hash, msg []byte) (r, s *big.Int, err error)

Sign data

func Verify ¶

func Verify(pub *PublicKey, h hash.Hash, data, sig []byte) bool

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 VerifyWithRS ¶

func VerifyWithRS(pub *PublicKey, h hash.Hash, data []byte, r, s *big.Int) bool

func XY ¶

func XY(D *big.Int, c elliptic.Curve) (X, Y *big.Int)

Types ¶

type PrivateKey ¶

type PrivateKey struct {
	PublicKey

	D *big.Int
}

ec-kcdsa PrivateKey

func GenerateKey ¶

func GenerateKey(c elliptic.Curve, randReader io.Reader) (*PrivateKey, error)

Generate the paramters

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)

解析私钥

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 ¶

type PublicKey struct {
	elliptic.Curve

	X *big.Int
	Y *big.Int
}

ec-kcdsa PublicKey

func ParsePublicKey ¶

func ParsePublicKey(derBytes []byte) (pub *PublicKey, err error)

解析公钥

func (*PublicKey) Equal ¶

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

Equal reports whether pub and x have the same value.

func (*PublicKey) Verify ¶

func (pub *PublicKey) Verify(msg, sign []byte, opts crypto.SignerOpts) bool

Verify asn.1 marshal data

type SignerOpts ¶

type SignerOpts struct {
	Hash crypto.Hash
}

SignerOpts contains options for creating and verifying EC-KCDSA signatures.

func (*SignerOpts) HashFunc ¶

func (opts *SignerOpts) HashFunc() crypto.Hash

HashFunc returns opts.Hash
