Constructor Detail

SALSA20_CHACHA20_POLY1305_PARAMS

public SALSA20_CHACHA20_POLY1305_PARAMS(byte[] nonce,
                                        byte[] aad)

Create a new Salsa20Chacha20Poly1305Parameters object with the given attributes.

Parameters:

nonce - nonce (This should be never re-used with the same key.)
length of nonce in bits (is 64 for original, 96 for IETF (only for chacha20) and 192 for xchacha20/xsalsa20 variant)

aad - additional authentication data. This data is authenticated but not encrypted.
