Lost 3 days worth of cracking. "Manually" resume?

ARGH. :mad: I have this hash that I've been working on for a while. Somehow my barswf.save file got corrupted, when I was about 80% through 9 char lower-alpha set. Effectively I lost all my progress on the 9 char set. I only have an Asus 8600GT "MAGIC" (the slow memory one) + a Q6600 quad core, so that's taken me about 3 days solid to get to. :wall:

I started BarsWF again from the 9 chr set, but then I had a theory...

Can someone set me straight on this? Judging from this thread: http://3.14.by/forum/viewtopic.php?f=8&t=59 I guessed that I could manually edit the barswf.save to advance the position of the calculation to somewhere near where I lost the last file. I bumped up the numbers in the 5th line of the .save file until BarsWF showed around the % completed as I had before.

What I want to know is: Does the "list" of hashes calculated and the progression stay the same for every cracking session? Or in other words, if I change the file from, say 18% completed to 79% completed, can I be sure that the part of calculation I've skipped contains the same hashes as my lost session? Does that make any sense? I want to skip the hashes that I calculated last time. I'm assuming that the hashes are not completely random, 'coz otherwise I don't see how the program could work.

This is what I did:

Code: Select all

0
f87a3e4d58f98544b23e3f7bd09d805a
md5
9
0 0 6 25 16 13 15 11 0 //<-- Change this line
36
48 49 50 51 52 53 54 55 56 57 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 
to this:

Code: Select all

0 0 28 21 2 29 18 27 12 
which got me to almost where I was before, allowing for a little overlap.

Anyone know for sure?

You mean same checked passwords? Yes, they are guaranteed to be the same as long as other options (like charset) are the same.

Ah, thank you. Yes, that was exactly what I meant, I just couldn't seem to explain it easily. I figured that was the way it worked, but I just wanted to be sure.

Thanks bars, go ahead and lock this thread.
