mcrypt decryption problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have been trying to set encryption using the mcrypt module. Everything seems to work, until the decrypt step, where only the first 8 characters of the encrypted string are decrypted. Here's the code I'm using to encrypt:

$mcrypt_key = "24 character key goes here";
$mcrypt_module = mcrypt_module_open(MCRYPT_TripleDES, "", MCRYPT_MODE_CBC, "");
srand ((float) microtime() * 1000000);
$mcrypt_iv = mcrypt_create_iv(mcrypt_get_iv_size($mcrypt_module), MCRYPT_RAND);
mcrypt_generic_init ($mcrypt_module, $mcrypt_key, $mcrypt_iv);
$art = mcrypt_generic($mcrypt_module, $art);
$art = base64_encode($art);
$mcrypt_iv = base64_encode($mcrypt_iv);
mcrypt_generic_end ($mcrypt_module);

The data is stored in a mySQL database, then retrieved later.


To decrypt:

$mcrypt_key = "24 character key goes here";
$mcrypt_module = mcrypt_module_open(MCRYPT_TripleDES, "", MCRYPT_MODE_CBC, "");
$art = base64_decode($art);
$mcrypt_iv = base64_decode($mcrypt_iv);
mcrypt_generic_init ($mcrypt_module, $mcrypt_key, $mcrypt_iv);
$art = mdecrypt_generic($mcrypt_module, $art);
mcrypt_generic_end ($mcrypt_module);

Only the first 8 characters of the encrypted string are decrypted properly.
