Unknown hash
#1
I have a john hash file. The signature $gpg$*0*1099991*.
How can I crack it with hashcat if the cat doesnt know this format?
The original file was encrypted with a symmetric key. Algorithm aes256.cfb
John shows segmentation fault Failing at address: 0x2c
Opencl device: Platform #0 name: Clover, version: OpenCL 1.1 Mesa 23.2.1-arch1.2

It helps but not too much) It seems like that hash can be cracked only by john. But the opencl implementation under arch has many bugs.
Which utility is used to create hashes from gpg specially for hashcat?

To extract hashes, use the tools that come with John the Ripper
hash generation tools for John the Ripper tend to add extra data like the filename. For this reason, the generated hashes usually need to be slightly modified to be accepted by Hashcat

Hashcat ver6.2.6 supports hash-type 17010
GPG (AES-128/AES-256 (SHA-1($pass)))

Please see here

or
hashcat -m 17010 --example-hashes
hashcat --hash-type 17010 --example-hashes

it seems, hashcat beta supports other gpg hash-type

Hashcat is being developed and tested on Ubuntu

Try Ubuntu.

In my experience, I got the right answer to my first question on this forum after two months.
