mech, qopGSS-API Mechanism and QOP files

/etc/gss/mech /etc/gss/qop

The /etc/gss/mech file contains a list of installed GSS-API security mechanisms. Each line of the file either contains a comment if the first character is '#' or it contains five fields with the following meanings:

Name
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.

This is a typical entry from /etc/gss/mech:

kerberosv5	1.2.840.113554.1.2.2	/usr/lib/libgssapi_krb5.so.8	-

This is a typical entry from /etc/gss/qop:

GSS_KRB5_CONF_C_QOP_DES		0x0100	kerberosv5
