How to "must contain" specific letters
Hi (and sorry for my english)
I'm a beginner, but I think this question is interesting.

How to "must contain" specific letters in the syntax.
For an example, I want hashcat searches only with "a" or "e".
I use this cmd:
cudaHashcat32.exe -m 100 -o found.txt hash.txt -1 ?l?d ?1?1?1?1 ?1?1?1?1?1

But to decrease the time, I don't want it tries "gklpdsmrb" but "galpdemrb" (with "a" and "e" only)
I really don't know if that is possible, can you tell me if it is?

yes, it is:

cudaHashcat32.exe -m 100 -o found.txt hash.txt -1 ?l?d ?1a?1?1?1 e?1?1?1
Thanks for this method, I knew it. I'm sure it will try "talmregrt" but, will it try "edsethatu" ?
I mean, the "e" and "a" not in the order you set ? (2nd and 6th position)
ok, thanks for the confirmation.
