Im going to distribute the BTC in relevance to how helpfull they were.
2.5 BTC goes to: techmix, phr33, K1773R
1.25 BTC goes to: BkkCoins, dooglus (since his guess was right, even i did screw it up!)
please leave me a PM with ur BTC address.
Thanks for this contest, it was fun (especially at the start)

BTW - I'm compiling a summary of the results in the (reserved) second post to this topic and will be adding some "what we have learned" kind of notes to it also.

Ooops - my bad - didn't see the 1's (this event has been rather tiring for me)...
"3a5Y+3a5Y=2x3a5Y(at least)\n"
"3a5Y+3a5Y=2x3a5Y(at least)\n"
December 28, 2012, 05:01:45 AM
Doh. So without the 1:s...
Alright. Thanks everyone!
Alright. Thanks everyone!

So the modified password was this?
"13a5Y+13a5Y=2x3a5Y(at least)\n"
(without the quotes)
"13a5Y+13a5Y=2x3a5Y(at least)\n"
(without the quotes)
that's correct - thought that I'd try and make it "twice as easy (at least)"...
%s+%s=2x%s(at least)
edit - oh, I'm late to this party.
I'm amazed this all worked out.

that's correct!

No. It was "3a5Y+3a5Y=2x3a5Y(at least)\n" "13a5Y+13a5Y=2x3a5Y(at least)\n"

what was the four char password?
dunno, the gpg passphrase is 41087438dbac5b77c3922cbe1f4d2f529ae3a4eb96a7534e4803361f1437f7e7I didn't get the 4 char pwd either but it would be possible now to go back and run it with logging the input pwd. I was piping them and didn't have any logging going on. It was 6m 8s into this final run at only 32k p/s. I was totally pumped and had gpg ready asking for the pwd and blockchain.info open on the import page... and when it got imported and didn't add the balance to my total I knew I was just beat.
Anyway, I wouldn't have got this far without K1773R and phr33 input. Especially about fixing the JTR program to check full pwd length. I hadn't noticed that. It was my first time using that tool.
I'd welcome any contribution to my firstbits at left but please don't feel obliged. It was fun and I was truly playing catch up all the way.

::EDIT
No, it does not give the right sha sum..

Great exercise, thx.
December 28, 2012, 04:53:50 AM
Oh - and the password was 3a5Y

For those who dont have enough hashing power, u can send me patterns per PM and il test em, if they match u get a portion of the 10BTC (going to distribute it fair to all who helped, including me).
Here are a few to try:
Code:
password="${password}+${password}=2${password}@L3AsT"
password="${password}+${password}=2.${password}@L3AsT"
password="${password}+${password}=2*${password}@L3AsT"
password="${password}+${password}=2x${password}@L3AsT"
password="${password}+${password}=2 ${password}@L3AsT"
password="${password}+${password}=2 . ${password}@L3AsT"
password="${password}+${password}=2 * ${password}@L3AsT"
password="${password}+${password}=2 x ${password}@L3AsT"
password="${password}+${password}=2${password}(at least)"
password="${password}+${password}=2.${password}(at least)"
password="${password}+${password}=2*${password}(at least)"
password="${password}+${password}=2x${password}(at least)"
password="${password}+${password}=2 ${password}(at least)"
password="${password}+${password}=2 . ${password}(at least)"
password="${password}+${password}=2 * ${password}(at least)"
password="${password}+${password}=2 x ${password}(at least)"
password="${password}+${password}=2${password} (at least)"
password="${password}+${password}=2.${password} (at least)"
password="${password}+${password}=2*${password} (at least)"
password="${password}+${password}=2x${password} (at least)"
password="${password}+${password}=2 ${password} (at least)"
password="${password}+${password}=2 . ${password} (at least)"
password="${password}+${password}=2 * ${password} (at least)"
password="${password}+${password}=2 x ${password} (at least)"

Damn It. Just found the key and it had been swept already!
Must have been just seconds....
5Hq96RktdCU3BL1U4b7Wxse2wWCiSRXierJdS68RE1Mf8BXphjg
I wonder if I could issue another spend with higher fees and have it go to me.... ha ha.
It's still unconfirmed.

If you don't manage to pip him with that then give me a BTC address and I'll send you 1 BTC for being so close!
