Functions

func Bech32DecodeBytes

func Bech32DecodeBytes(rawString string) (hrp string, decodedKey []byte, err error)

Bech32DecodeBytes decodes a bech32 string.

func Bech32EncodeBytes

func Bech32EncodeBytes(toEncode []byte, hrp string) (encodedBytes string, err error)

Bech32EncodeBytes encodes a bech32 string.

func CreateDoubleSha256

func CreateDoubleSha256(data []byte) []byte

CreateDoubleSha256 creates a double sha256 hash from data.

func CreateSha256Hash

func CreateSha256Hash(data []byte) []byte

CreateSha256Hash creates a hash from data.

func GenerateRandomBytes

func GenerateRandomBytes(n int) ([]byte, error)

GenerateRandomBytes returns securely generated random bytes. It will return an error if the system's secure random number generator fails to function correctly, in which case the caller should not continue.

func PrngIsAvailable

func PrngIsAvailable() bool

PrngIsAvailable determines wether or not pseudo-random number generation is available on this device. Adapted from https://git.io/Jt9mW

func TLVRecordToBytes

func TLVRecordToBytes(record ...tlv.Record) []byte

TLVRecordToBytes encodes a TLV (type-length-value, defined in BOLT #1: https://git.io/JLCRq ) into a byte slice.
