Functions ¶
func CreateAddress ¶
Creates an ethereum address given the bytes and the nonce
func FromECDSA ¶
func FromECDSA(priv *ecdsa.PrivateKey) []byte
FromECDSA exports a private key into a binary dump.
func FromECDSAPub ¶
func GenerateKey ¶
func GenerateKey() (*ecdsa.PrivateKey, error)
func GenerateOneTimeKey ¶
Generate OTA account interface
func GenerateOneTimePrivateKey2528 ¶
func GenerateOneTimePrivateKey2528(privateKey *ecdsa.PrivateKey, privateKey2 *ecdsa.PrivateKey, destPubA *ecdsa.PublicKey, destPubB *ecdsa.PublicKey) (retPriv1 *ecdsa.PrivateKey, retPriv2 *ecdsa.PrivateKey, err error)

GenerteOTAPrivateKey generates the privatekey for an OTA account using receiver's main account's privatekey Pengbo added, TeemoGuo revised
func HexToECDSA ¶
func HexToECDSA(hexkey string) (*ecdsa.PrivateKey, error)
HexToECDSA parses a secp256k1 private key.
func IntToPublicKey ¶
IntToPublicKey converts Big int data structure to PublicKey data structure
func Keccak256Hash ¶
Keccak256Hash calculates and returns the Keccak256 hash of the input data, converting it to an internal Hash data structure.
func LoadECDSA ¶
func LoadECDSA(file string) (*ecdsa.PrivateKey, error)
LoadECDSA loads a secp256k1 private key from the given file.
func PublicKeyToInt ¶
PublicKeyToInt converts PublicKey data structure to Big int data structure and return outInt[0] as return value. storage structure is like ((x,y)(x,y)(x,y)(x,y)....)
func RingSign ¶
func RingSign(M []byte, x *big.Int, PublicKeys []*ecdsa.PublicKey) ([]*ecdsa.PublicKey, *ecdsa.PublicKey, []*big.Int, []*big.Int, error)
RingSign is the function of ring signature Pengbo added, Shi,TeemoGuo revised
func Rsa_decrypt ¶
RSA decryption algorithm interface Shi，TeemoGuo added
func Rsa_encrypt ¶
RSA encryption algorithm interface Shi，TeemoGuo added
func SaveECDSA ¶
func SaveECDSA(file string, key *ecdsa.PrivateKey) error
SaveECDSA saves a secp256k1 private key to the given file with restrictive permissions. The key data is saved hex-encoded.
func Sign ¶
func Sign(hash []byte, prv *ecdsa.PrivateKey) (sig []byte, err 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)
ToECDSA creates a private key with the given D value.
func ToECDSAPub ¶
func ToECDSAUnsafe ¶
func ToECDSAUnsafe(d []byte) *ecdsa.PrivateKey
ToECDSAUnsafe blidly converts a binary blob to a private key. It should almost never be used unless you are sure the input is valid and want to avoid hitting errors due to bad origin encoding (0 prefixes cut off).
func ValidateSignatureValues ¶
ValidateSignatureValues verifies whether the signature values are valid with the given chain rules. The v value is assumed to be either 0 or 1.
