comment What challenge should I use in a challenge-response proof-of-work?
I should have made that clearer: when I say "stateless" I mean in the same way that HTTP is stateless. On your point about PRNGs: I'm using /dev/urandom, which doesn't bog down (I never knew, thanks!) but loses entropy after a while. That would't be a problem, but I have to use it again shortly after the proof-of-work, to generate keys. Now my thinking is that an attacker could reduce the security of those keys by firstly draining the entropy of /dev/urandom. Would that be a valid concern?

revised What is the proper way to use a client nonce?
Removed some superfluous to improve readability, modified the layout slighty. Replaced "cnonce" with "client nonce" for Google (but left one of them in)

comment Cipher for Product Registration?
If you're going to send binary data to the user, it makes sense to encode it in something other than hexadecimal. Take a look at Crockford's Base32, which avoids characters that can be confused easily.

added a link to wp:sophie germain prime, hopefully distinguishes it from "safe prime" (which I thought it was talking about for a minute there)
