I'm running PHP 4.3.7 on Apache 2.0.49 on an Xp machine, and after many hours of googling over the internet I found that the easiest way to use the mcrypt function was to do this: <?php $key = "Secret Key"; //Encrypt Function function encrypt($encrypt) { global $key; $iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND); $passcrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $encrypt, MCRYPT_MODE_ECB, $iv); $encode = base64_encode($passcrypt); return $encode; } //Decrypt Function function decrypt($decrypt) { global $key; $decoded = base64_decode($decrypt); $iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND); $decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $decoded, MCRYPT_MODE_ECB, $iv); return $decrypted; } ?> Notice the base64_encode, which makes it able to be inserted into MySQL easily. Now to encrypt just run the encrypt("text");, and to decrypt use the decrypt("encrypted text"); I hope this helps anyone. ---- Manual Page -- http://www.php.net/manual/en/ref.mcrypt.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+43662 Delete -- http://master.php.net/manage/user-notes.php?action=delete+43662&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+43662&report=yes Search -- http://master.php.net/manage/user-notes.php
