mcrypt decryption problem

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. -- mark hurty | mark@hurty.com | 309.764.0911
