USAGE

$x = new NMR;

$x->aes_cmac($data, $key);

$x->aes_pmac($data, $key);

$x->OMAC2($data, $key);

$x->vmac($key, $m, $nonce, $taglen);

$x->aes_siv_encrypt($Key,$Sn,$plaintext);

$x->aes_siv_decrypt($Key,$Sn,$cipher);

[$Sn is an array of additional data (for example AAD or nonce)]

$x->aes_eax_encrypt($Message,$Key,$Nonce,$Header);

$x->aes_eax_decrypt($Cipher,$Key,$Nonce,$Header);

TEST VECTORS

$x->test_cmac(); $x->test_pmac(); $x->test_OMAC2(); $x->test_vmac(); $x->test_aes_siv(); $x->test_aes_eax();
