Functions

func AddPadding

func AddPadding(src []byte) []byte

func Decode

func Decode(wif string) ([]byte, error)

Decode can be used to turn WIF into a raw private key (32 bytes).

func DecryptCBC

func DecryptCBC(data, iv, key []byte) (decryptedData []byte, err error)

func EncryptCBC

func EncryptCBC(data, iv, key []byte) (encryptedData []byte, err error)

func GetAddressString

func GetAddressString(prefix string, key *btcec.PublicKey) string

func GetPrivateKey

func GetPrivateKey(wif string) (*btcec.PrivateKey, error)

func GetPublicKey

func GetPublicKey(wif string) ([]byte, error)

GetPublicKey returns the public key associated with the given WIF in the 33-byte compressed format.

func GetPublicKeyString

func ParsePublicKey

func ParsePublicKey(key string) *btcec.PublicKey

ParsePublicKey parses address to public key, returns nil on error

func RemovePadding

func RemovePadding(b []byte) ([]byte, error)
