The Kerberos Keytab Binary File Format

The Kerberos Credential Cache Binary File Format
http://josefsson.org/shishi/ccache.txt

I have written a standalone ccache parser for Shishi, see:

Shishi also contains a keytab parser, but it is not possible to use it
outside of Shishi.  However, that should ideally be changed.  For the
code, see:
