  The name of this GSS-API mechanism.

Object identifier
  The OID for this mechanism.

Library
  A shared library containing the implementation of this mechanism.

Kernel module (optional)
  A kernel module containing the implementation of this mechanism (not yet supported in FreeBSD).

Library options (optional)
  Optionsal parameters interpreted by the mechanism. Library options must be enclosed in brackets ([ ]) to differentiate them from the optional kernel module entry.

The ```/etc/gss/qop` file contains a list of Quality of Protection values for use with GSS-API. Each line of the file either contains a comment if the first character is '#' or it contains three fields with the following meanings:

QOP string
  The name of this Quality of Protection algorithm.

QOP value
  The numeric value used to select this algorithm for use with GSS-API functions such as gss_get_mic(3).

Mechanism name
  The GSS-API mechanism name that corresponds to this algorithm.
