PHP Bug Type: mcrypt related
Bug description: Decryption does not work
Description:
------------
Encryption appears to work, as plain text becomes ciphertext, but
decryption using either the mcrypt_decrypt or mdecrypt_generic functions
returns the ciphertext unchanged as the result of the function call.
Reproduce code:
---------------
$key = "ae2b1fca515949e5d54fb22b";
$td = mcrypt_module_open ('tripledes', '', 'cbc', '');
$iv_size = mcrypt_enc_get_iv_size ($td);
$iv = mcrypt_create_iv ($iv_size, MCRYPT_RAND);
if (mcrypt_generic_init ($td, $key, $iv) != -1) {
/* Encrypt it */
$c_t = mcrypt_generic ($td, "testing");
mcrypt_generic_deinit ($td);
echo "ciphertext: ". $c_t;
/* Decrypt it */
mcrypt_generic_init ($td, $key, $iv);
$p_t = mdecrypt_generic ($td, $c_t);
echo " plaintext: ". $p_t;
mcrypt_generic_deinit ($td);
mcrypt_module_close ($td);
}
Expected result:
----------------
This should produce the following:
ciphertext: _sometext_ plaintext: testing
Where _sometext_ is the ciphertext created based on the random input
vector.
E.g.
ۏȫ
Actual result:
--------------
ciphertext: ۏȫ plaintext: ۏȫ
