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 Ecrecover 

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

Ecrecover 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(hash []byte, prv *ecdsa.PrivateKey) ([]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 ToECDSA 

func ToECDSA(d []byte) (*ecdsa.PrivateKey, error)

func TxStatus 

func TxStatus(txReceipt *TransactionReceipt, isToken bool) bool

TxStatus get transaction status

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.
