thanks for the detailed explanation, looking forward to taking the kraken for a spin!
guessing by some posts on the mailing list, rainbow table generation is still ongoing and the berlin tables are just a subset of the entire a5/1 key space? i read somewhere that the current set of tables can only crack 22% of all sessions, is this due to the amount of tables that have been generated so far? -- jakob borg [email protected] On Thu, 21 Oct 2010 13:16 -0500, "James Nobis" <[email protected]> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA512 > > You may want to read the thread on the set: > http://lists.lists.reflextor.com/pipermail/a51/2010-June/000657.html > > "(284 & 492 are optional)" > > I'm not entirely sure what that means or why they are optional but it > seems 492 exists from the > torrents and 284 does not. > > You may also want to read the thread on the different table formats: > http://lists.lists.reflextor.com/pipermail/a51/2010-June/000675.html > > TableConvert may be found via: > https://svn.reflextor.com/tmto-svn/tinkering/A5Util/TableConvert > http://reflextor.com/trac/a51/browser/tinkering/A5Util/TableConvert > > It mentions fitting up to 47 tables in the format at 41.9Gb per table > onto a 2TB hd.
