cryption

I need a program/script for php to encrypt/decrypt data without the need of
any special add-on to php.

Have a look at this,

Tim specified the need to be able to encrypt and decrypt data. crypt() is a one-way function - no decrypt available. Sure, you can compare crypt()ed strings but you can't get your starting value back.

Might be a bit better suited to the task.

ok this is the type of cyrption i want but this requires a module to be installed with php, does anyone have a homemade function to do this?

There is an example on this site, in the Algorithm section of the code libary.

Just out of interest, what are you trying to do ?

If you want to transfer information securly then this is not the way to do it, as the data is transmited from a browser is not encrypted, and will only be encyypted on the server.

If you are just trying to store encrypted data, then this is fine.
