Can't workout why my mask isn't working.

[AutomaticCoding]

Using hashcat-GUI, first I may want to note it's sort of annoying that it doesn't exit CMD after it's done. Yes, I understand it doesn't using a bat file, etc, but it's annoying.

Next, reason why I posted in this forum is it's generating these arguments:

Code:

cudaHashcat-plus64.exe --attack-mode 3 --remove --outfile C:\Users\Nicholas\Desktop\file.txt.out --outfile-format 2 C:\Users\Nicholas\Desktop\file.txt ?uld?uld?uld?uld?uld?uld

What I presume each one does:
-attack-mode 3 == bruteforce
--remove == remove hashes from file.txt when found
--outfile C:\-snip-\file.txt.out == output file to dump found hashes to
--output-file format 2 == plain
C:\-snip-\file.txt == file full of hashes
?uld?uld?uld?uld?uld?uld - Mask

Now, what I want:
6 letters, [A-Z0-9a-z].

If I have something like "Hi" in the file, and I do:
?u?l
it works fine. But if I have "Hi" in the file and do:
?ul?ul
it does nothing.

My file.txt:

Correct hashes in order:

Code:

<?php
    echo(md5("Hi") . "\n");
    echo(md5("L0L") . "\n");
    echo(md5("LOL") . "\n");
    echo(md5("lol") . "\n");
    echo(md5("£$^£%") . "\n");
    echo(md5("Fjgld") . "\n");
    echo(md5("yrti") . "\n");
    echo(md5("sad") . "\n");
    echo(md5("fdgd") . "\n");
    echo(md5("48fH$") . "\n");
    echo(md5("Pizza") . "\n");
    echo(md5("Yo") . "\n");
?>

Yes, I realize none of them are six characters and they're all five, but, better safe than sorry. (It does go up 1-6, right? Not just only scan 6?)
