Thanks for your advice. How about this ?

 static struct fmt_tests tests[] = {
+/*
+ * The following two test vectors: "USER" and "service" are case-insensitive
+ */
        {"$V$9AYXUd5LfDy-aj48Vj54P-----", "USER"},
        {"$V$p1UQjRZKulr-Z25g5lJ-------", "service"},
+/*
+ * The following one test vector: "President#44" is case-sensitive
+ */
        {"$V$S44zI913bBx-UJrcFSC------D", "President#44"},
        {NULL}
+/*
+ * This format supports both case-sensitive and case-insensitive passwords,
+ * so this format should set FMT_CASE
+ */
 };



Thanks,

Kai
