krb2john.py "Unable to find kerberos.salt value"

[Anouar1a1]

Hey creator,
I hope you're fine. I'm here to report a failure in your krb2john.py tool that is like this:
python3 krb2john.py kerbers.xml
[-] Hash might be broken, etype != 23 and salt not found!

Currently unsupported etype 18 found!
Unable to find kerberos.salt value. Please report this bug to us!
I hope you'll solve it soon.
See you.

Hi @Anouar1a1. What revision of krb2john.py do you use? We need to make sure it includes this commit:

commit 1ba735068b9cff3055555e216e0b90d9e62e156d
Author: exploide <me@exploide.net>
Date:   Tue Feb 18 16:44:34 2020 +0100

    krb2john.py: python3 compatibility
    
    krb test cases from John wiki succeed, hopefully that's enough

Older revisions were Python 2 only, and could very well fail to extract the salt if run with Python 3.
