My mosaic page has pointers for these topics an many others: ftp://furmint.nectar.cs.cmu.edu/security/README.html For these two topics, there is a section on factoring and a pointer to http://www.commerce.net. I have added a lot since it first came out. It can really be used like a FAQ at this point. If you are looking for cypherpunks things, this is a good place to start. Please let me know if you know of any cypherpunk pages I am not yet pointing to. -- Vince
