Functions

func EntropyFromMnemonic 

func EntropyFromMnemonic(mnemonic string) ([]byte, error)

EntropyFromMnemonic takes a mnemonic generated by this library, and returns the input entropy used to generate the given mnemonic. An error is returned if the given mnemonic is invalid.

func GetAddressFromMnemonic 

func GetAddressFromMnemonic(words string, net Network) string

func GetAddressFromPrivateKey 

func GetAddressFromPrivateKey(priv string, net Network) string

func GetPrivateKeyFromMnemonic 

func GetPrivateKeyFromMnemonic(words string, net Network) string

func GetWordList 

func GetWordList() []string

GetWordList gets the list of words to use for mnemonics.

func IsMnemonicValid 

func IsMnemonicValid(mnemonic string) bool

IsMnemonicValid attempts to verify that the provided mnemonic is valid. Validity is determined by both the number of words being appropriate, and that all the words in the mnemonic are present in the word list.

func IsRegIdStr 

func IsRegIdStr(regId string) bool

func MnemonicToByteArray 

func MnemonicToByteArray(mnemonic string, raw ...bool) ([]byte, error)

MnemonicToByteArray takes a mnemonic string and turns it into a byte array suitable for creating another mnemonic. An error is returned if the mnemonic is invalid.

func NetworkToChainConfig 

func NetworkToChainConfig(net Network) (*chaincfg.Params, error)

func NewEntropy 

func NewEntropy(bitSize int) ([]byte, error)

NewEntropy will create random entropy bytes so long as the requested size bitSize is an appropriate size.

bitSize has to be a multiple 32 and be within the inclusive range of {128, 256}

func NewMnemonic 

func NewMnemonic(entropy []byte) (string, error)

NewMnemonic will return a string consisting of the mnemonic words for the given entropy. If the provide entropy is invalid, an error will be returned.

func NewSeed 

func NewSeed(mnemonic string, password string) []byte

NewSeed creates a hashed seed output given a provided string and password. No checking is performed to validate that the string provided is a valid mnemonic.

func NewSeedWithErrorChecking 

func NewSeedWithErrorChecking(mnemonic string, password string) ([]byte, error)

NewSeedWithErrorChecking creates a hashed seed output given the mnemonic string and a password. An error is returned if the mnemonic is not convertible to a byte array.

func SetWordList 

func SetWordList(list []string)

SetWordList sets the list of words to use for mnemonics. Currently the list that is set is used package-wide.

func WriteContractScript 

func WriteContractScript(writer *WriterHelper, script []byte, description string)
