"> where would you start auditing the code? It's just too much.

Actually, it is a very small part of the tree..."

I am aware that compilers can be coded to introduce "features" into binaries that are not in the actual source code itself.
So with all due respect and possibly much ignorance on my part, what is a code audit going to achieve if one uses the shipped compiler to
compile the source? Unless one codes ones own compiler can any binary be trusted?

Would not reversing the compiled code lead to a proper insight? Are the compiled binaries that handle these crypto functions so complex that
they cannot be reversed by a skilled assembly coder? I guess that such a coder would have to be an expert cryptographer too, or at least
collaborate with one.

My curiosity is genuine, I am trying to educate myself about such things.

regards
Dave
