Functions ¶
func SecretBox ¶
SecretBox takes a message buffer, a random nonce, and a key and writes the encrypted, authenticated cypher text into the cypherTextOut buffer. The message buffer must have SecretBoxZeroBytes() worth of zero-padding at the start of it. The key may be reused across messages, but the nonce must be used only once for a given key. \
Returns: 0 on success, non-zero on failure.
func SecretBoxKeyBytes ¶
func SecretBoxKeyBytes() int
SecretBoxKeyBytes specifies the size of the symmetric key used in the secret box functions.
func SecretBoxMacBytes ¶
func SecretBoxMacBytes() int
SecretBoxMacBytes specifies the size, in bytes, of the MAC (Message Authentication Code) which is inserted at the start of the cypher text.
func SecretBoxNonceBytes ¶
func SecretBoxNonceBytes() int
SecretBoxNonceBytes specifies the size, in bytes, of the nonce to be used with the secret box functions.
func SecretBoxOpen ¶
SecretBoxOpen opens the authenticated cypher text produced by SecretBox and returns the original message plain text. The cypher text is authenticated prior to decryption to ensure it has not been modified from the original. The messageOut buffer must be the same size as the cypherText buffer and will be padded with SecretBoxZeroBytes() worth of leading zero bytes.
Returns: 0 on success, non-zero on failure
func SecretBoxZeroBytes ¶
func SecretBoxZeroBytes() int
SecretBoxZeroBytes specifies the number of zero-byte padding which must be prsent at the start of the message buffers passed to the non-easy version of the functions.
