Higher Portability

[GrandAdmiralThrawn]

Your code contains x86_64 specific assembly, as well as AES-NI instructions any maybe other things that depend on more modern x86 CPUs (this won't even work on Core 2...).

Could you maybe make this more portable, so that it can run on older chips as well? I'd be specifically interested in testing Intel Netburst architecture chips, which were developed by a different team than the P6/Core line of CPUs.

None of them have AES-NI though, and most of them are 32-bit, so it'd be nice to have a generic C version of this tool that compiles and runs on any x86_32 & x86_64 chip.
