I suggest looking at mcrypt.  There is a PHP module, and you could either
call out from R to the mcrypt program or use libmcrypt and C calls.    It
supports AES, and other standard things.

There's no real saving of effort in using weaker ciphers, and you really
don't want to be implementing the processing yourself.
