hey there,
i try to create a mask file for PMKID's coming from routers of a provider, who uses WLAN default passwords and the format is always the same...

the WPA keys are always in this format:

xxxx-xxxx-xxxx-xxxx where x is either a character from a-z or a number from 0-9.

the position of letters or numbers are variable..

can anyone give me an example or help?

thanks in advance,
shokka

Your mask will be -1 ?l?d ?1?1?1?1-?1?1?1?1-?1?1?1?1-?1?1?1?1
Don't forget to add -a3 mode as well
But our banned friend was right - this keyspace is huge and can't be bruteforced, at least for WPA

hey gpuhash_me,

thanks a lot for your answer.
you're right, the fact that it will be a huge keyspace is plausible.
im just interested in the mask, that i could use.

the other thing is, that the whole key is randomized, it will mean that i have to exlude all the keys, which will repeat same signs or numbers in the key like this:
aaaa-aaaa-aaaa-aaaa
aaaa-aaaa-aaaa-aaab

and so on...

an example key looks like this:
jncy-fbz9-63ld-wtak

i guess this is not possible with just a mask, and the keyspace will stay very large...

any other ideas? :-(

The keyspace for aaaa-zzzz without repeated characters is 406250.

Eg:

abab
abac
abad
abae
abaf
...
zyzu
zyzv
zyzw
zyzx
zyzy

So still your total keyspace is still 406250^4. Impossible unless you know the pattern which is used to generate these.

Edit: just noticed your key has digits too making it even harder
