Really, the only way to go. This software rocks!
mcrypt has gone unmaintained for years now, even major bugs are not getting fixed. People looking for similar functionality should check out Botan (http://botan.randombit.net/), cryptopp (http://www.cryptopp.com/) or libgcrypt (http://directory.fsf.org/project/libgcrypt/) these days.
