hashcat Forum - Using hashcat with maskprocessor

Pages: 1 2

Hello

I have forgotton a part of my password for a VeraCrypt Container. So I want to find it again with the mask processor.
For doing that I used following command

Code:
hashcat -a 3 13711 partIremember?d?s --increment 17:19 /path/to/the/My\Volume

because it's burned on a dvd.
For that I've got the following answer

Code:
hashcat (v5.1.0) starting...

* Device #1: WARNING! Kernel exec timeout is not disabled.

            This may cause "CL_OUT_OF_RESOURCES" or related errors.

            To disable the timeout, see: https://hashcat.net/q/timeoutpatch

* Device #2: Not a native Intel OpenCL runtime. Expect massive speed loss.

            You can use --force to override, but do not report related errors.

Hash '13711': Token length exception

Is there anybody who could give me a hint, what I've made wrong?

TIA

Is the container mounted? You'll need to provide the path to the raw file, the raw device, or else extract the first 512 bytes and save that to a file to provide to hashcat.

Also, from your cmdline ... if you don't remember 17 to 19 additional characters, you won't crack it any time soon.

Good evening royce Smile

!
Thank you for your answer!

No, it isn't mounted.

Oh no, that seems to be one mistake. I don't remember 4 to 6 additional characters. 17 to 19 is the total length Wink

You're missing "-m" in front of the hash mode and "--increment 17:19" is absolutely the wrong syntax. Where did you find that?

Ha! I think I've just always wanted that syntax; didn't even give me pause. Big Grin

Ok, thank you undeath Smile

! I just can't tell you, where I found this. But I've read it in a howto - anywhere. What would be the right syntax, when I'm looking for 4 to 6 unknown characters?

TIA

Code:
hashcat -h | grep increment

 -i, --increment                |      | Enable mask increment mode                           |

     --increment-min            | Num  | Start mask incrementing at X                         | --increment-min=4

     --increment-max            | Num  | Stop mask incrementing at X                          | --increment-max=8

Code:
hashcat -a 3 -m 13711 part_I_remember?a?s --increment-min=4 --increment-max=6

right?

Thank you in every case!

you need to add --increment too
the --increment command line switch enables the increment feature (and min/max options are further restrictions/limits)

Code:
hashcat -a 3 -m 13711 part_I_remember?d?s --increment --increment-min=4 --increment-max=6

I'm going to try it!
