First things first.
This is not meant as a cracking question, its meant as a hacking question.
Can someone please tell me how do I get a password, if for example I know for sure that a particular character appears or not and also another character I know appears in say, 4th position.
#1. What are the meanings of "cracking" and "hacking" in your post?
#2. Get a password from where?
Cracking means stealing someone else's password for malicious reasons or doing something to harm others. Hacking means exploring everything.
Now I call this hacking because I will know how much time does it take for my password to be cracked by testing it out myself. Just to weigh my chances of being secure if someone might be doing shoulder browsing. And I just want to explore everything. That's it.

This is NOT going to turn into a hacking/cracking flame. There are plenty of threads on this forum already debating that. Stealing passwords is stealing passwords there is no hack or crack about it. Cad, if you were attempting to find out how things work, he went about it the wrong way. Your first post was very vague about pattern matching passwords and you gave no indication about where and how you were obtaining these passwords. We see plenty of kids trying to get their hands on malicious programs and scripts and LQ will play no part in it.
It is a bit odd how cracking has become to mean something illegal/immoral, really cracking is the breaking of secured data, hacking is the use of technology beyond the creator's intended purpose.
I think what crabboy is getting at is cad's apparent intentions. I don't think his concern is a debate on the terminology of hacking vs. cracking. The way cad conveyed his information (or lack of) maybe gave crabboy an indication that he was maybe up to no good?
