Mojo Nation uses Wei Dai's Crypto++ library.  Either v3.2 or v4.0 based on
flags given at compile time (v4.1 should work with no or minor tweaking; we
haven't tried).

What we've crudely wrapped from Crypto++ is the following:

* Modular arithmetic (modval module) used for RSA and other signature style
* DESX stream cipher in CBC mode (incorrectly named tripledescbc module)
* crypto++'s random number generator (randsource module)

The C++ used in Crypto++ is a *real* pain in the ass.  It makes heavy use of
templates, etc.  (read: a porting and wrapping nightmare).  We'd ultimately
prefer not to use Crypto++ and our custom interface at all if something
better (prefferably based on a C library such as OpenSSL) is available.
