Functions

func Open

func Open(out, nonce, box, key []byte) ([]byte, error)

Open does what the name suggests

func Seal

func Seal(out, nonce, message, key []byte) []byte

Seal does what the name suggests

func SharedKey

func SharedKey(secretKey [32]byte, publicKey [32]byte) ([32]byte, error)

SharedKey computes a shared secret compatible with the one used by `crypto_box_xchacha20poly1305`
