For convenience, the GSS-API does allow mechanisms and QOPs to be displayed in human-readable form. On Solaris systems, two files, /etc/gss/mech and /etc/gss/qop, contain information about available mechanisms and available QOPs. If you do not have access to these files, then you must provide the string literals from some other source. The published Internet standard for that mechanism or QOP should serve that purpose.
The /etc/gss/mech file lists the mechanisms that are available. /etc/gss/mech contains the names in both the numerical format and the alphabetic form. /etc/gss/mech presents the information in this format:
Mechanism name, in ASCII
Shared library for implementing the services that are provided by this mechanism
Optionally, the kernel module for implementing the service
A sample /etc/gss/mech might look like Example C-1.

The /etc/gss/qop file stores, for all mechanisms installed, all the QOPs supported by each mechanism, both as an ASCII string and as the corresponding 32-bit integer. A sample /etc/gss/qop might look like the following example.
