Subject: New formats: KRB5-18 and KRB5-23


I send you two new formats, named KRB5-18 and KRB5-23 and both tools :
krb5_util.patch and kdcdump2john.

The idea is as follows:
- On a KDC server, with the krb5_util patched tool, dump the unencrypted
- With kdcdump2john, get relevant informations and create a hash list for
- The 2 formats corresponds to, respectively, aes256-cts-hmac-sha1-96 (the
recommended format) and arcfour-hmac (faster to crack)

That way, it is possible to get user passwords from the extended key used
by Kerberos during the authentication part.
I hope it will be useful.

Looking forward for your comments,
