Using hashcat with maskprocessor - here: veracrypt - Snoop - 08-18-2019
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\VolumeFor 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

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

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
!Thank you for your answer!

I don't remember 4 to 6 additional characters. 17 to 19 is the total length

RE: Using hashcat with maskprocessor - here: veracrypt - undeath - 08-18-2019
You're missing "-m" in front of the hash mode and "--increment 17:19" is absolutely the wrong syntax. Where did you find that?
RE: Using hashcat with maskprocessor - here: veracrypt - royce - 08-18-2019
Ha! I think I've just always wanted that syntax; didn't even give me pause.

! 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=8RE: Using hashcat with maskprocessor - here: veracrypt - Snoop - 08-19-2019

Code:
hashcat -a 3 -m 13711 part_I_remember?a?s --increment-min=4 --increment-max=6right?
Thank you in every case!
RE: Using hashcat with maskprocessor - here: veracrypt - philsmd - 08-19-2019
you need to add --increment too
the --increment command line switch enables the increment feature (and min/max options are further restrictions/limits)

Thank you Phil
!Code:
hashcat -a 3 -m 13711 part_I_remember?d?s --increment --increment-min=4 --increment-max=6I'm going to try it!
