Encryption using PHP with Nothing Special Compiled In

[David T. Ashley]

I have plain vanilla PHP (bcmath is the only thing special I'm aware of). I
don't have mcrypt compiled in.

Are there any functions that can be used for reversible encryption?

(I have thought about how I would choose the key -- that isn't an issue.)

I'm only interested in [reversibly] encrypting a 192-bit AES key that will
be stored in a database. I'm not interested in encrypting large amounts of
data.

I once checked some classes written in pure PHP that implement blowfish
algorithm. I can't remember the exact names but one of them was pcrypt:

I'm not an encryption guru but pcrypt seemed to work fine.
