If you build the OpenSSL crypto as a static library you should be able to utilize it without including everything else in your app, depending on your compiler/linker options.

I'll look at it. But is there really no possibilty to get OpenSSL library smaller, only with BIGNUMs. I ask that because I did very much with these functions.
