04:00 < andytoshi> interesteng comment from steven ... we have made the music2 secretnonce (i.e. "session id") difficult to store because storing it is almost certainly a bad idea and can easily lead to reuse
04:01 < andytoshi> but steven would like to store these because he's doing a lot of sessions in parallel, plans to abort most of them, but wants to run all of them to the point where there's only half a round left
04:01 < andytoshi> technically he could complete them but that's expensive
04:01 < andytoshi> i wonder if there's a "safe" way we can enable this use case

13:33 < real_or_random> I don't think so. he's doing exactly what we tell people not do ^^
13:33 < real_or_random> not to do
13:35 < real_or_random> I see the point that keeping the nonce is much more efficient but it's still not a great idea.
13:41 < real_or_random> if all other session params are fixed, he could perhaps store a MAC of the nonce and the parameters along with the nonce. this will at least stop someone without the MAC key from tampering with the session parameters in the db.
