+ *against expected output to see whether regression tests pass.  The
+ *input file is a very primitive format.
+ *First line: enctype
+ *second line: key to pass to string2key; also used as salt
+ *Third line: second key to pass to string2key
+ *fourth line: pepper1
+ *fifth line:  pepper2
+ *scanf is used to read the file, so interior spaces are not permitted.  The program outputs the hex bytes of the key.
