Functions

func Decrypt

func Decrypt(msg, nonce, pubkey, privkey common.RawBytes, algo string) (common.RawBytes, error)

Decrypt decrypts a message for a given nonce and public/private keypair.

func Encrypt

func Encrypt(msg, nonce, pubkey, privkey common.RawBytes, algo string) (common.RawBytes, error)

Encrypt takes a message, a nonce and a public/private keypair and returns the encrypted and authenticated message. Note: Nonce must be different for each message that is encrypted with the same key.

func GenKeyPair

func GenKeyPair(algo string) (common.RawBytes, common.RawBytes, error)

GenKeyPair generates a public/private key pair.

func InitMac

func InitMac(key common.RawBytes) (hash.Hash, error)

func Mac

func Mac(mac hash.Hash, msg common.RawBytes) (common.RawBytes, error)

func MathRandSeed

func MathRandSeed()

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

func Nonce

func Nonce(l int) (common.RawBytes, error)

Nonce takes an input length and returns a random nonce of the given length.

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.
