[RESOLVED] Simple encrypt/decrypt needed for my script

[rvpals]

Hi,

I have a website that uses cookie to store some information on the users' hard disk, I want to encrypt this cookie info as a string, then store the encrypted string to the cookie. Next time when user login, the script reads the encrypted string from cookie, then decrypt it and I can use the decrypted string.

Is there a simple built-in PHP function that does this? I don't need it to store password level security material, just so that user can't peek in the cookie data.

Thanks

or you store some unique id in the cookie and in a database table you store the same unique id and the corresponding data
