Hi all,
I have need to encrypt and decrypt information going into and out of a mysql
database. I am using PHP and have found the following code sample. I don't
know how secure this is and am wondering if there is a stronger encryption I
can use.
$key is a string of characters and $string is the value to be encrypted.
$encrypted = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5(KEY),
$string, MCRYPT_MODE_CBC, md5(md5(KEY))));
Security is not my forte, so I don't really understand how strong this really
is. It seems to generate a 44 character string. Any thoughts are appreciated.
Thx,
Jeff
