Who knows where you can get the RSA PHP class?

Question

PHP

There is a topic on Habré about RSA PHP CLASS (Khaled Al-Sham'aa RSA Class PHP), but the link is a complete bummer. Google is silent like a partisan. Could you share links, al classes dear "you programmers")
(If possible, class with AES would also be useful)
Thanks in advance.
