GNUPG Symmetric help - bayes - 11-15-2017
Hello,
Last year, I encrypted a text file using gpg --symmetric foo.text
Checking the default options on my machine, it appears to be using SHA1 and then AES256
Password was lost, and I really need into that file. So considering purchase of a GPU (or two) and trying to brute force it.
Is this something I can do with hashcat? If so, would someone please guide me to the correct method. Assume I'll need to extract key from the file (John the Ripper has a nice utility for that), but then I don't know how to start brute forcing that key with hashcat.
Any and all help would be greatly appreciated. Thank You!!!

hashcat currently has no direct support for PGP/GPG.
But John the Ripper does have the 'gpg-opencl' format, which is significantly faster on GPU that the basic 'gpg' format, so using a GPU should still be quite a bit faster.
