Hi, I need to encrypt a string like 'hello world', using a passkey. But I also need to be able to decrypt the encrypted phrase using the same passkey. I noticed in MySQL there are functions like AES_ENCRYPT()<http://dev.mysql.com/doc/refman/5.1/en/encryption-functions.html#function_aes-encrypt>
However, I need the encrypted phrase to be returned as a string, since it will be passed to a URL as a parameter. Does anyone have any suggestions on how to overcome this issue, using MySQL. I know that there are many components available out there, but I can't install any third party components on the hosting server. Cheers Neil
