I assume the -u option allows us to set characters to a particular position. can we get some more information on this function?

how is this option used?

Great program though!! I'm getting 270m/s on md5 hashes with 10000 hashes loaded.

I really need to sit down and write documentation...

The charset files work as follows:

"-c" uses the first line of the charset file (if it's a single line or multiple line) and uses this in ALL positions.

"-u" uses each line as the charset for that position.

So:

Code: Select all

abcd
ABCD
1234
6789


If we use this file with "-c" it will use "abcd" in ALL positions.

If we use this file with "-u" it will use "abcd" in the first position, "ABCD" in the second position, "1234" in the third, and "6789" in the fourth.

Does this make sense? If it doesn't, I'll try to provide more details.

I think this makes sense.
EDIT:my second attempt at understanding
./CUDA-Multiforcer-32 -v -h MD5 -o found -u /root/chars --min=9 --max=9 --lookup -f hashes
if my -u file looks like this

Code: Select all

1
2
3
1234567890
1234567890
1234567890
1234567890
1234567890
1234567890


my output will be
123000000 - 123999999

below was my first attempt at understanding
so this syntax
./CUDA-Multiforcer-32 -v -h MD5 -o found -u /root/chars --min=10 --max=10 --lookup -f hashes
The -u /root/chars = 123 on the first line

should get me this output?
1230000000 - 1239999999
3210000000 - 3219999999
etc...

save the passwords to found

crack MD5

min and max of 10 characters.

Thanks for trying to help me understand this. I am very impressed with the speed.

That will get you in the realm of the following:

1110000000-1119999999
1120000000-1129999999
...
3320000000-3329999999
3330000000-3339999999

Perfect, Thank you very much.
