Among other comments, it was pointed out that I had not included "hash.curve". To generate this file I did the following main() { POINT point; CURVE curve; init_opt_math(); init_rand(); rand_curv_pnt(point,curve); save_curve("hash.curve",curve,point); close_rand(); } This was done during development and I forgot about it. A simpler patch is to fix an error finding the file with a call to rand_curv_pnt to generate it. Kind of interesting that way for hashing your secret key. If everyone uses a different curve to generate their secret key, access to the machine is necessary to even begin to think about cracking any pass phrase. Don't know if actually adds any security, but it is an interesting concept. As for why I didn't put up a tar file, no particular reason. It's source for a particular machine (MachTen on a Mac) and I figured every C compiler is different so some hacking will be required by anyone interested. Once more bugs are fixed such as the one above, I'll put it up in a more easily compilable form. And thanks for the comments so far. I'll do my best to keep up with them. Patience, persistence, truth, Dr. mike
