Kraken-win32 is a customized version of the GSM A5 cipher cracker. (see http://reflextor.com/trac/a51) This is a GSM A5/1 cipher cracker that requires some rainbow tables (~2 TiB) and some keystream bits to crack the cipher session key Kc.
I ported this tool to run on win32 (whilst still runing on linux) and redesigned the “user interface” a little bit.
Instead of developer-oriented debug output, kraken-win32 prints some mode user-friendly output and has some neat multi-client, multi-job network service.
improved ServerCore to allow console + remote connection
new network protocol
ATI CAL kernels in extra files
Support some ATI Radeon HD3xxx models (uses slower GPU code then!)
config file allows to specify a sector offset (required for win32)
merged find_kc into Kraken for calculating Kc directly
startup speedup using cached table indexes stored on index-disk (~40 Mib per .idx file)
will release memory (from ~1.6 GiB) when idle for 30 minutes (down to ~40 Mib)
fixed some rare crash situations
introduced some new random crash situations ;)
execute “wmic diskdrive list” on your windows console to get the \\.\PhysicalDrive-name of your data disks
use some fdisk tool to get the start sector of the data partition on your disks (e.g. sector 63)
specify above information in your tables.conf: ‘Device: \\.\PhysicalDrive1+63 40’
please specify your tcp port if you don’t want to have port 8866
every command will return a status code from the list below
for every queued request, you will receive an ID
results will get printed out with the ID of the request
(<parm> are required parameters, [parm] are optional)
crack <bits1> [<COUNT1> <bits2> <COUNT2>]
will try to find the Kc if bitsx and COUNTx are given. if just the bits are given and no COUNT etc, kraken will report the intermediate result as usual, but with some other formatting.
show some server details and its status.
just like a NOP or IDLE command known from other protocols
start the key search as known from original kraken
cancel currently processed request
successfully finish current request immediately with a faked result key. its mainly for testing network clients.
perf disk [reads]
queue random block reads to test disk speed. without parameter [reads] it will queue 2000 reads. retrieve results with ‘stats’ command.
get details about the hard disks. i.e. blocks read, acess time etc
quit (console only)
will quit the client
wnd_hide / wnd_show
will hide/show the console window on windows.
will release the table indexes from memory. they will be automatically reloaded upon the next crack command.
