Hi, wc export.hash returns: 1 1 16809 export.hash the file only has one very long line, and it is going directly from the output of gpg2john... is there another way than gpg2john export.tgz.gpg > export.hash that I should be using to avoid corruption? when running gpg2john there are some other errors I didn't notice. Unknown string-to-key(s2k 166) unknown version (90). This file is encrypted with CAST5 according to gpg... --format=gpg didn't make any difference... I tested it on an AES gpg file and it works. It seems to be CAST5 specifically... But I'm not expert in this. cheers On Thu, Jul 6, 2017 at 9:17 PM, Solar Designer <solar@...nwall.com> wrote: > On Thu, Jul 06, 2017 at 08:26:16PM +0800, noir maru wrote: > > i have a file i created with tar -cz export| gpg -c -o export.tgz.gpg > > > > i run gpg2john export.tgz.gpg > export.hash > > > > at this point gpg2john complains that MDC is missing. export.hash is > > created and that starts with $gpg$*0....... > > > > and then i run john with ./john --wordlist wordlist.lst export.hash > > What does this command say? - > > wc export.hash > > > there are some errors which i have included below and no password is > found, > > though the known password is in the wordlist. > > Of course, nothing would be found when the hashes are misdetected as > tripcode.
