This module provides GSS-API / SSPI Key Exchange as defined in :rfc:`4462`.
.. note:: Credential delegation is not supported in server mode.
.. note::
`RFC 4462 Section 2.2
<https://tools.ietf.org/html/rfc4462.html#section-2.2>`_ says we are not
required to implement GSS-API error messages. Thus, in many methods within
this module, if an error occurs an exception will be thrown and the
connection will be terminated.
.. seealso:: :doc:`/api/ssh_gss`

generate an "x" (1 < x < q), where q is (p-1)/2.
p is a 128-byte (1024-bit) number, where the first 64 bits are 1.
therefore q can be approximated as a 2^1023. we drop the subset of
potential x where the first 63 bits are 1, because some of those will
be larger than q (but this is a tiny tiny subset of potential x).
