Ahhhh... Bill, yes I know that none of those are operating systems.
Operating systems have nothing to do with the problem space. To make
things easy, lets assume the same operating system (but it really
doesn't matter).

And no, we are not using a symmetric algorithm (like you've listed
above), we are using an asymmetric algorithm (sometimes referred to as
public-key).

Ok Bill, your killing me know...

Why does anyone need public/private keys (i suggest doing some reading
about encryption)? Hmmm... although I do appreciate your reply, are
you just messing with me now?

Lets just say, we have a need for an asymetric (public-key) algorithm.

I guess what we're looking for is "Encryption System (provider)
Independant" keys (if they exists). In other words, we would like to
generate the key using some Java JCE provider, then be able to use the
public key with some native language security provider. I guess when
I said language independant, like you pointed out, its really
"provider" independant.

I've seen that RSA Security provides both a Java and C provider and
I'm going to look at them as a possible solution, however they cost
money and we would like to do the "free" route if we can...

Thank you for your reply!
