Functions

func GenerateKey

func GenerateKey(entropy [EntropySize]byte) (sk SecretKey, pk PublicKey)

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

func Verify

func Verify(pk PublicKey, message []byte, sig Signature) bool

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

Types

type PublicKey

type PublicKey *[PublicKeySize]byte

PublicKey is used to verify signatures.

type SecretKey

type SecretKey *[SecretKeySize]byte

SecretKey is used to sign messages.

type Signature

type Signature *[SignatureSize]byte

Signature is used to authenticate a message.

func Sign

func Sign(sk SecretKey, message []byte) (sig Signature)

Sign signs the message with secretKey and returns a signature.
