Custom charset with mask files - swing - 01-18-2019

Hi,

How do I provide my custom charsets when using mask file?

For example, I'm able to crack my UTF-8 password this way:

Code:
hashcat64.exe -m 0 md5.txt -w 3 -O -a 3 -1 charsets\my1.hcchr -2 charsets\my2.hcchr -3 ?l ?1?2?1?2?3?3?3

But how do I put such mask into a mask file?
When I try:

Code:
hashcat64.exe -m 0 md5.txt -w 3 -O -a 3 -1 charsets\my1.hcchr -2 charsets\my2.hcchr -3 ?l test.hcmask

and put into test.hcmask

Code:
?1?2?1?2?3?3?3

I get error: Custom-charset 1 is undefined

If I try to put my custom charsets into mask file, like this:

Code:
charsets\my1.hcchr,charsets\my2.hcchr,?l,?1?2?1?2?3?3?3

And run like this:

Code:
hashcat64.exe -m 0 md5.txt -w 3 -O -a 3 test.hcmask

Then password is not found

Can you please suggest how to pass custom charset into a mask file
Thanks!

I found 2 ways of doing this, you can ether pipe them or place them as hexchars in the attack command.
Both attacks have severe impact on performance.

Yes, hex chars did the trick, thanks. And yes, I have the same performance penalty as in your case - some generated unicode symbols are invalid. But it is still better than generating huge dictionary manually with a python script :/

@swing
did you try putting my1.hcchr and my2.hcchr into the root directory of hashcat and use a mask like this:

my1.hcchr,my2.hcchr,?l,?1?2?1?2?3?3?3

I think it's just a matter of if the file is found correctly. also note that \ is a special character if it comes to hcmask syntax, so maybe you need to use \\ instead.

anyways, you could also put/copy the content of the files from my1.hcchr directly into the hcmask file or as suggested use --hex-charset
