Re: Introduce randommess in keypress timings
Is there anything that tells us how many bits of entropy are found in the brainsong (rhythm, melody) of random users?
Five minutes of Swedish death metal should get you around 256 bits. mn

Wrong entropy source, if you go for Norwegian black metal you get at least 1024 bits of entropy [0]. Having said that, Putin's foreign policy speeches will get you at least 512 bits of entropy in the same time frame. Peter. [0] From an estimate done at Tons of Rock in Norway in June of this year.
Morelike 1 bit. Amirite? [The song you selected.] Personally, I like to pipe /dev/urandom to my speakers for sourcing keypress-timing based passwords. -Travis On Fri, Oct 9, 2015 at 11:25 AM, Peter Gutmann <pgut001@cs.auckland.ac.nz> wrote:

Me too. It is well known [0] this is very relaxing. Rarely, just to refresh my memory, I XOR /dev/urandom with a Windows NT CD played _backwards_ ;) [1] [0] to those who know it [1] according to ancient jokes, this MUST NOT be used for RandomMess entropy because of enormous bias to certain number

You mean "256 bpm", right? -- Pozdrawiam, Michał "rysiek" Woźniak Zmieniam klucz GPG :: http://rys.io/pl/147 GPG Key Transition :: http://rys.io/en/147
