Functions

func MathRandSeed

func MathRandSeed()

Seed math/rand's default generator with a random value, once.

func RandInt64

func RandInt64() int64

RandInt64 returns a random int64 value. The returned value can be negative.

func RandUint64

func RandUint64() uint64

func Sign

func Sign(sigInput, signKey common.RawBytes, signAlgo string) (common.RawBytes, error)

Sign takes a signature input and a signing key to create a signature. Currently only ed25519 is supported

func Verify

func Verify(sigInput, sig, verifyKey common.RawBytes, signAlgo string) error

Verify takes a signature input and a verifying key and returns an error, if the signature does not match. Currently only ed25519 is supported.
