keytab file format - exporting arcfour keys from active directory

[Michael B Allen]

Hi,

Is there any documentation on the keytab file format? From scanning
the code the rules are not clear and leaves me wanting of definitive
documentation.

I want to write an encoder (and I suppose decoder) in plain C for
inclusion in the pwdump2 [1] program for exporting Kerberos keys from a
MS Windows domain controller. This would be largely for debugging purposes
(e.g. for Ethereal to decrypt things).

If someone would be kind enough to provide me with the details I
will furnish a web page with the modified program, source code, and
documentation.

Thanks,
Mike
