I've ported libcrypto++ an libhash++ to the psp.
I hope i made the makefile portable. It compiles/installs fine using my windows VISTA+minpspw.

}well you can encrypt and decrypt things with this.
I made an example today which shows a working way to decrypt and encrypt a file using AES:
main.cpp

}libhash++ is just hashes link MD5 and SHA
libcrypto++ has encryption like AES etc. (and md5 as sha things) so you can decrypt it back.
I even don't know what those all does...
I ported them and the sees to work (at least the things i tested).
