Thanks scintill,

That's a nice compact implementation.  I like it.  I was just looking through the code...

I forgot that Bitcoin-Qt uses key recovery for the signatures.  Meaning, that you only need to provide the signature, and the public key can only be one of four different values.  Thus, signature and a couple extra bits.  This is something I don't have implemented in any of libraries yet, and it doesn't look trivial.   But the code is all there in the C++ from scintill, and I am considering putting it into my own "EncryptionUtils.h/.cpp".

I assume you're not going into the C++ code in Armory...?  Just making standalone python files?  That will work for now, though I can see that having the C++ key recovery would be useful.

If you want to take a shot at implementing it in EncryptionUtils.h/.cpp, I will throw in another 0.5 BTC (on success, of course!).  I already have EC math operations available in the library.  I'm pretty sure you can do most of it with what's already there.  Though, you might have to add a sqrt-function or something (I cheated with UncompressPoint, by just letting Crypto++ do the uncompression for me, so  I didn't actually implement it).

Maybe we can designate 5340 Satoshies as a Gavin.

Put a limit of 200 posts and 55 hours on the Newb section, would solve that.

even after 350 million years of evolution.

BBQcoin is ancient history.

I am looking for a team of individuals who would like to be involved with an exciting new project to build the next big coin. I will need:

- Graphic designers
- Programmers
- Marketers

I have been mining and investing for some time and will provide financial benefits to those whose are willing to help.

Please PM or reply to this thread.

I'm a graphic designer and marketer (I was one of those clickbank/ WF users back in the day). I primarily need a programmer and I want to get the whole alt forum involved so we have set launch dates etc. I want full transparency with everyone.
