Functions ¶
func CompressPubkey ¶
CompressPubkey encodes a public key to the 33-byte compressed format.
func CreateAddress ¶
CreateAddress creates an aichain address given the bytes and the nonce
func CreateAddress2 ¶
CreateAddress2 creates an aichain address given the address bytes, initial contract code hash and a salt.
func DecompressPubkey ¶
DecompressPubkey parses a public key in the 33-byte compressed format.
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 HexToECDSA ¶
func HexToECDSA(hexkey string) (*ecdsa.PrivateKey, error)
HexToECDSA parses a secp256k1 private key.
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 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 ToECDSAUnsafe ¶
func ToECDSAUnsafe(d []byte) *ecdsa.PrivateKey
ToECDSAUnsafe blindly 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 UnmarshalPubkey ¶
UnmarshalPubkey converts bytes to a secp256k1 public key.
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.
func VerifySignature ¶
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.
