Functions

func Decrypt

func Decrypt(key *[KeySize]byte, in []byte) ([]byte, bool)

Decrypt takes encrypted byteslice 'in' and decrypts it using 'key' byte array Returns decrypted byteslice and 'true' if successful. See secretbox.Open

func Encrypt

func Encrypt(key *[KeySize]byte, in []byte) ([]byte, bool)

Encrypt takes byteslice 'in' and encrypts it using 'key' byte array Returns encrypted byteslice and 'true' if successful, otherwise returns nil and 'false'

func NewKey

func NewKey() *[KeySize]byte

NewKey generates a new NaCl key.
