Visual Basic 4.0 encryption prog.

I just scored a copy of visual basic 4.0 and I was wondering how feasible it would be to write a program for Window$ 95 that would use RSA or IDEA and the Win95 exchange interface. I plan on buying Applied Cryptography probably on Fri. when I get paid.
	My requirements/goals are: 100% compatibility with M$ Exchange, ease of use (Point & Click/ drag & drop) and last but not least, STRONG public key encryption using "off-the shelf
code. 
	So my ??? Is this: Is it possible? Or should I just go out and buy a C++ compiler.
I don't really care about ITAR or any of that other BS, I just won't put MY name on it.

You've already put your name on it by asking this question and providing 
so much detail on what tools you would use and what you want to do. :-)

But there is no reason why this isn't possible in ANY language.  You'll 
just have to write a lot of code by hand, or port to VB... especially the 
large-number routines.

I don't see any reason why crypto routines written in C can't be 
converted to .DLL files - then you can call them from VB or whatever.  No 
need to convert them to VB.
