Hashcat + wlangenpmkocl how to convert back to plaintext ?

Hash mode 2501 (16801, 22001) doesn't make me wince.
I really love this "verification" modes and that is exactly the reason, why I explained the purpose of them to Atom and asked him to add this modes (apart from this, it was also the reason for me to code hcxdumptool and hcxtools).
That include hash mode 22000 to get full benefit of reuse of PBKDF2 over PMKID end EAPOL.

This are my experiences (PMK verification) on hash mode 2200x:
$ hashcat -m 22001 -w4 --nonce-error-corrections=0 hash.22000 pmk.list -o found

Please notice:
This is only a demonstration.
To save time, I used --nonce-error-corrections=0 (NC).
Due to packet loss during capturing (some of the capturing tools are not able to detect this), a few of the hashes require a higher NC to recover the PSK. Unfortunately this will increase task time, too. For a demonstration it is not worth it.

I don't use the ancient modes 250x and 1680x any longer since Atom added 2200x to hashcat.

oh don't you worry I have a full treatise in preparation Smile I'm actually enjoying t his very much. Once all this is laid out the ultimate objective is to see if it's possible to guess part of the password.

btw I was saying mode 2501 makes you wince hehe the 22ks I know you like. What do I have to do just convert the hccapx to 22000 mode or something ?
(and if I'm using a PMK it's 22001 I'm assuming ?)

So yeah I've been reading the information you've posted and it's a little hard to understand so I need to ask, is it possible to extract PART of a password ?

What would happen if I took a hash, and only removed say the first 2 characters, and tried to brute force that ? I know I'm not wording it properly yet but you get what I'm trying to say. Maybe the whole problem here is trying to guess the entire password at once.

Meanwhile the PMK is at 80 million out of 90 so in a couple hours it'll be ready for testing we'll see what happens

EDIT: Forgot to mention, I have this little superstition that the needle is always at the bottom of the haystack so to speak. Is there a way to search backwards wit hthe masks and dictionnaries ? Dicts I suppose I can just reverse the order and pipe it or whatever but what about the masks ? Without rules preferably sounds needlessly tedious for this specific task unless I'm off base of course.
