Method Detail

cryptoAuthKeygen

void cryptoAuthKeygen(byte[] k)

Generate an authentication key.

Parameters:

k - Auth key of size Auth.KEYBYTES.

cryptoAuth

boolean cryptoAuth(byte[] tag,
                   byte[] in,
                   long inLen,
                   byte[] key)

Computes a tag for the message in, whose length is inLen bytes, and the key k.

Parameters:

tag - Tag of size Auth.BYTES.

in - A message.

inLen - Message size.

key - The key as generated by cryptoAuthKeygen(byte[]).

Returns:

True if successful.

cryptoAuthVerify

boolean cryptoAuthVerify(byte[] tag,
                         byte[] in,
                         long inLen,
                         byte[] key)

Verifies that the tag stored at h is a valid tag for the message in whose length is inLen bytes, and the key k.

Parameters:

tag - The tag.

in - The message.

inLen - Message bytes.

key - The key as generated by cryptoAuthKeygen(byte[]).

Returns:

True if successful verification.
