Looking for ECPP software
Don't know if this is the right forum,but I'm looking for an opensource ECPP implementation. As you know, Morain's ECPP is properitary, and Primo is also properitary and for Windows only.

I'm not aware of any, but I agree that it would be nice if there were an open source implementation of ECPP.

I think Primo is no longer restricted. The only reference I could find is this one:

Is the ECPP algorithm patented or something?

Aren't mp3audio,mpegvideo and so also patented?
Why then there exists some open source software like lame or ffmpeg doing the job? nugget

Why not write your own? It isn't that difficult. ECPP is a lot easier than APRCL (aka cyclotomy tests).

In the UK and, I believe, the rest of Europe building a patented invention without license from the patent holder is an offense regardless of intended purpose. At least, that's what I seem to remember MSFT's IP lawyers telling me. Paul

With the DMCA it's even murkier; there's an exception in the law that allows researchers to break commercial copyright protection schemes, but the exception doesn't let researchers publish their results. My understanding of the elliptic curve business is that there are a lot of different patents, for different types of curves, curve arithmetic, and curve applications like crypto schemes PS: further reading on ECC patents Last fiddled with by jasonp on 20080826 at 17:01
