28 * This file contains tests for the KRB-FX-CF2 code in Kerberos, based on the
29 * PRF regression tests. It reads an input file, and writes an output file.
30 * It is assumed that the output file will be diffed against expected output to
31 * see whether regression tests pass. The input file is a very primitive
32 * format.

34 * Line 1: enctype

40 * scanf is used to read the file, so interior spaces are not permitted. The
