A partnership between Distributed.net and the Electronic Frontier
Foundation has successfully decoded a DES message encrypted as a challenge
by RSA, demonstrating that DES is not secure.

\"You don\'t have to work all day long to break DES  Press announcement soon!\"

\"EFF\'s DES Cracker makes headlines again! Working with Distributed.Net, our
machine was the winner of RSA\'s DES-III Challenge (DES Cracker accounted
for 80mil. of the total Distributed.Net 220mil. keys per second) - press
release forthcoming (Jan. 19, 1999)\"

and

>From http://www.distributed.net (Since it\'s difficult to get on there
right now:)
---------------------------------------------------
It is with considerable excitement (and quite a bit of relief) that I can
now announce that the DES-III contest is officially ended.
At 07:15 am PST (14:15 UTC), just about the time when we all started
getting worried about the 24-hour waypoint, the solution to DES-III
arrived. The winning key, 92 2C 68 C4 7A EA DF F2, revealed the
plaintext message:
The unknown message is: See you in Rome (second AES conference,
March 22-23, 1999
The winning key was found by EFF\'s Deep Crack hardware, and submitted to
the distributed.net servers immediately. RSA confirmation of the success
followed shortly thereafter.
It\'s truly been a joy and a thrill to work with John Gilmore and the
other talented and clued people at EFF. Were it not for their
contributions to distributed.net, the 24-hour deadline would have been
a much more difficult goal to reach.
I\'ll be running stats for the partial 19-Jan work up to the point of
success and posting them this afternoon for the archives.
More details will follow soon as the dust settles, RSA is planning a
12:00 noon PST announcement at the RSA \'99 Convention. Both John Gilmore
and our own Peter Gildea will be in attendance.
Here\'s a few statistics on our aggregate success:
Start of contest: January 18, 1999 at 09:00 PST
End of contest: January 19, 1999 at 07:15 PST
Elapsed Time: 22 hours 15 minutes
Percentage Complete: 22.2%
Size of keyspace: 72,057,594,037,927,936
Keys Tested: 16,017,142,616,948,736
Blocks Tested: 29,834,253
Overall Keyrate: 199 Gkeys/sec
Peak Keyrate: 250 Gkeys/sec

99年的旧闻也拿出来贴?

64bit的就没有那么容易了吧?
3des就更不容易了。

IPSEC规范建议3des很有道理。
good good study, day day up。
