Functions

func GenerateKey

func GenerateKey(rand io.Reader) (publicKey *[PublicKeySize]byte, privateKey *[PrivateKeySize]byte, err error)

GenerateKey generates a public/private key pair using randomness from rand.

func MakePublicKey

func MakePublicKey(privateKey *[PrivateKeySize]byte) (publicKey *[PublicKeySize]byte)

MakePublicKey makes a publicKey from the first half of privateKey.

func Sign

func Sign(privateKey *[PrivateKeySize]byte, message []byte) *[SignatureSize]byte

Sign signs the message with privateKey and returns a signature.

func Verify

func Verify(publicKey *[PublicKeySize]byte, message []byte, sig *[SignatureSize]byte) bool

Verify returns true iff sig is a valid signature of message by publicKey.
