I have put together a package for Cantsin 2 Signatures, to generate the keys, sign documents and check signatures.

I've been looking this over and it's a nice job. The code is clean and orderly. I haven't had a chance to play with it yet, but it looks like everything is done the right way. For example, it doesn't tell you how many valid signatures a file has, it outputs a fragment of the file for each valid signature. The database of known keys has the nice property that you can name each key anything you like. The source code is completely unencumbered. This is great! For some reason, it has been the custom to issue free software with all sorts of restrictions, in particular restrictions which hamper its commercial use. But, if we are giving it away to people so they will use it, why restrict it? If somebody can use it to start a cypherpunk company, this is a Good Thing. (This can even be a Very Good Thing for the original programmer. ;-) It might be a good idea to publish the SHA1 checksum of the file you are distributing. The checksum of the file I got (cantsin.tar.gz) was: D054C9E4ABD5CEE0C5A4343E5D1E2EF91C00048A I may not approve of the restrictions on free speech in Germany, but at least the German government isn't trying to stop people from publishing arithmetic. The truth is, that for Monty Cantsin's activities, he would get a better deal on free speech if he were German.
