Below is the test vectors of DOMINOSEC8_fmt_plug.c:

static struct fmt_tests tests[] = {
        {"(HsjFebq0Kh9kH7aAZYc7kY30mC30mC3KmC30mCluagXrvWKj1)", "hashcat"},
        {"(HosOQowHtnaYQqFo/XlScup0mC30mC3KmC30mCeACAxpjQN2u)",
"pleaseletmein"},
        {NULL}
};

If I want to change the "hashcat" -> "hashca\xF4" which changes the last
character. How can I test the "hashca\xF4" with some input files ? I think
I can not use the wordlist mode and write "hashca\xF4" directly to the
wordlist file.

Thanks,

Kai
