Subject: Re: gpg2john working for symmetric encryption?
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
