I don't know of anything offhand in R and anything beyond very simple stuff would be rather slow in an interpreted language. You can always create character translations and such using functions such as chartr().

There is GnuPG (http://www.gnupg.org), which provides a broad range of algorithms via a CLI interface, which can be called via system().
