Unread post Password pattern syntax help
Dear tateu,

After a few months of not accessing one of my containers, I can't remember my correct password even though I've probably used it 300 times. I've been trying to use the BrutusGUI txt instructions to create the correct pattern that I should be trying, but what I'm trying to do is a bit too complicated for me.

These are the parameters of my password that I remember:

1) it begins with "h43900"
2) it is between 12 and 20 characters long (I'm pretty sure it's about 18 characters long)
3) it definitely contains "ui" "!xp" and "AMD", but I don't where in the password they appear, nor in what order
4) it likely contains all, some, or none of "@" "#" "89" "$", but I'm not certain
5) there may be a few other characters throughout the password, but I don't think I'm forgetting more than 4 at most.

My best guess is that my password looks something like: h34900???ui?AMD!xp, where the ?'s are characters that I don't know, and I don't know where they appear (just put them in this example where I think I'm forgetting characters).

Any help is greatly appreciated. And thanks for writing this program!

You'll likely never crack it. That's just way too complicated, you have way too many unknowns (items 3, 4 and 5 in your list).

If you knew your password looked something like h34900???ui?AMD!xp, you could use, h34900[a-zA-Z0-9@#$]{0-3}ui[a-zA-Z0-9@#$]{1}AMD!xp, but the only thing you are sure of is that it starts with h34900 so it could be:

h34900(a|b|c|d|e|f|g|h|i|j|k|l|m|n|o|p|q|r|s|t|u|v|w|x|y|z|A|B|C|D|E|F|G|H|I|J|K|L|M|N|O|P|Q|R|S|T|U|V|W|X|Y|Z|@|#|$|ui|AMD|!xp){3-7:1}

This would always put h34900 at the beginning and select 3 through 7 items with no repeats from the list of items contained inside of the parentheses. This would take approximately 87,000 days on my dual Xeon machine running 16 threads.

Thanks so much for your response; this helps quite a bit because you cleared up the trouble I was having with how to input the password pattern. I'm going to try and get lucky by narrowing down what the missing potential characters could have been. Cheers!
