Functions

func CompressPubkey 

func CompressPubkey(pubkey *ecdsa.PublicKey) []byte

CompressPubkey encodes a public key to the 33-byte compressed format.

func DecompressPubkey 

func DecompressPubkey(pubkey []byte) (*ecdsa.PublicKey, error)

DecompressPubkey parses a public key in the 33-byte compressed format.

func GenerateKey 

func GenerateKey() (*ecdsa.PrivateKey, error)

GenerateKey 生成s256的私钥

func MarshalPrivateKey 

func MarshalPrivateKey(key *ecdsa.PrivateKey) ([]byte, error)

func MarshalPrivateKeyX509 

func MarshalPrivateKeyX509(key *ecdsa.PrivateKey) ([]byte, error)

func MarshalPublicKey 

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

func MarshalPublicKeyX509 

func MarshalPublicKeyX509(pub *ecdsa.PublicKey) ([]byte, error)

func RecoverPubkey 

func RecoverPubkey(hash, sig []byte) ([]byte, error)

RecoverPubkey returns the uncompressed public key that created the given signature.

func S256 

func S256() elliptic.Curve

S256 returns an instance of the secp256k1 curve.

func SigToPub 

func SigToPub(hash, sig []byte) (*ecdsa.PublicKey, error)

SigToPub returns the public key that created the given signature.

func Sign 

func Sign(prv *ecdsa.PrivateKey, hash []byte) ([]byte, error)

Sign calculates an ECDSA signature.

This function is susceptible to chosen plaintext attacks that can leak information about the private key that is used for signing. Callers must be aware that the given hash cannot be chosen by an adversery. Common solution is to hash any input before calculating the signature.

The produced signature is in the [R || S || V] format where V is 0 or 1.

func UnmarshalPrivateKey 

func UnmarshalPrivateKey(curve elliptic.Curve, data []byte) (*ecdsa.PrivateKey, error)

func UnmarshalPrivateKeyX509 

func UnmarshalPrivateKeyX509(curve elliptic.Curve, data []byte) (*ecdsa.PrivateKey, error)

func UnmarshalPublicKey 

func UnmarshalPublicKey(curve elliptic.Curve, data []byte) (*ecdsa.PublicKey, error)

func UnmarshalPublicKeyX509 

func UnmarshalPublicKeyX509(curve elliptic.Curve, data []byte) (*ecdsa.PublicKey, error)

func Verify 

func Verify(pub *ecdsa.PublicKey, hash []byte, signature []byte) bool

func VerifySignature 

func VerifySignature(pubkey, hash, signature []byte) bool

VerifySignature checks that the given public key created signature over hash. The public key should be in compressed (33 bytes) or uncompressed (65 bytes) format. The signature should have the 64 byte [R || S] format.
