[RC5] - Is it done???
rc5-64 successfully completed
On 14-Jul-2002, after 1757 days of searching the winning key to RSA Labs' RC5-64 project was successfully recovered by distributed.net. 0x63DE7DC154F4D039 was returned by a P3-450 in Japan running Windows 2000.
I cannot load anymore units so whats up???? Have I been crunching for nothing???
[Sep 26 16:37:45 UTC] RC5: Discarded E4FC048D:30000000:7*2^28

This other page at DNET seems to indicate otherwise http://stats.distributed.net/projects.php?project_id=5

Weird, can you fetch any units? When I dump, my cows drop off like they have been shot!

I still have blocks in my PProxy (only 448 though).
September 26th, 2002, 12:47 PM #7
ACK!!! ECCP all the way baby!! Plus UD of course.

Okay, I give in too.
Looks like it is really over.

For those who haven't looked at the link already...
distributed.net completes rc5-64 project (list announcement)
september 25, 2002
RC5-64 HAS BEEN SOLVED!
On 14-Jul-2002, a relatively characterless PIII-450 in Tokyo returned the winning key to the distributed.net keyservers. The key 0x63DE7DC154F4D03 produces the plaintext output:
The unknown message is: some things are better left unread
Unfortunately, due to breakage in scripts (dbaker's fault, naturally) on the keymaster, this successful submission was not automatically detected. It sat undiscovered until 12-Aug-2002. The key was immediately submitted to RSA Labs and was verified as the winning key.
So, after 1,757 days and 58,747,597,657 work units tested the winning key was found! While it's debatable that the duration of this project does much to devalue the security of a 64-bit RC5 key by much, we can say with confidence that RC5-64 is not an appropriate algorithm to use for data that will still be sensitive in more than several years' time. On the distributed computing front, however, the RC5-64 project clearly demonstrates the viability of long-term, volunteer-driven, internet-based collaborative efforts. The next time someone bemoans the public's short attention span or need for instant gratification you should remind them what 331,252 people were able to accomplish by joining together and working for nearly five years. distributed.net's RC5-64 project clearly shows that even the most ambitious projects can be completed by volunteers thanks to the combined power of the internet and distributed computing.
Ignoring artificially high numbers resulting from network difficulties, we completed 86,950,894 workunits on our best day. This is 0.12% of the total keyspace meaning that at our peak rate we could expect to exhaust the keyspace in 790 days. Our peak rate of 270,147,024 kkeys/sec is equivalent to 32,504 800MHz Apple PowerBook G4 laptops or 45,998 2GHz AMD Athlon XP machines or (to use some rc5-56 numbers) nearly a half million Pentium Pro 200s.
Over the course of the RC5-64 project, 331,252 individuals participated. We tested 15,769,938,165,961,326,592 keys.
We apologize for the latency in the announcement, but scheduling conflicts with RSA Laboratories and difficulties in reaching the winning participant (who has asked to remain anonymous) introduced the additional delay to the process.
Also, please consider joining us on SlashNET IRC on Saturday 28-Sep-2002 @ 21:00 UTC (5:00PM EDT) for an online Q+A session on the RC5-64 project and the future plans for the distributed.net network. Not only are we looking forward to moving on to RC5-72 but we're currently reshaping the framework of the dnetc architecture to better accommodate additional projects. We're hoping to attract some new and motivated partners with good ideas and a need for cycles.
Thanks to RSA Labs for continuing to offer challenges that reward distributed efforts!

Well then congrats to DVNT1!!! You made an awesome effort.
and cwizard too of course.
eagle1, you made your move too late!

Since there will appear to be some machines available....... can I convince any of ya to join the D2OL team???
?? PLEASE !
[D2OL] Loosing Ground! HELP!!!
Has more info for anyone interested in helping
hey you can't fault me for tryin !!

With a P3-450 sending in the winning point for RC-5, maybe my 433 Celeron will win ECCp.Misfortune, n. The kind of fortune that never misses.
September 26th, 2002, 01:30 PM #15
Well at least I did break 5 million block mark on the proxy before the anouncement LOL
Uninstalling Dnet now...

And so the book closes.. and we are at an end to the story.. It was long, and not without its faults.. but an overall joy, most would say..
Some like DVNT may cry.. and some like Snowman may smile.. but most of will just sigh.. and say.. thank god.. lets move on =) j/k
now that was one heck of a long project.. u got so close dvnt.. I personal hope to see some of u guys on some of the other DC teams.. unless u r retiring.. In away it is nice to know one of the projects actually rapped up.. I hope eccp is finished soon myself..In life one must Chill
September 26th, 2002, 01:48 PM #17
My RC5 herd is already converted!! ECCP for now though I will keep an open mind about others for the old RC5 herd.
September 26th, 2002, 01:50 PM #18
I think you guys should form an "Ex-RC5'ers" mini team under TIMO in ECCp...that's just MO of course.
You're more than welcome to join EvilRick.
September 26th, 2002, 01:58 PM #19
hell Evil.. u know u don't want no one joining u.. u know u r the one man mini team =)
but eccp doesn't have long either till it is done.. and with an influx of rc5 ppl in eccp.. it woudl be over pretty fast..In life one must Chill

wow.. pretty amazing!
Congrats folks, you stuck with it and carried her to the finish line
A few new UD members would be very well appreciated seeing as we got BBT a little ways in the rear view window... and well.. personally I'd like to keep them there
Hmm... what to do after ECCp ends though.. will have to do some research
Congrats again!Helicopters don't fly; they vibrate so much and make so much noise that the earth rejects them.
