Watch the Video made by me.I hope that you will find this useful.

Okay Here's a bit of Explanation :-

Crunch is a tool that is pre-installed with backtrack.
It is a very usefull tool that helps you to generate wordlists for bruteforcing, according to your need.

So, How we do it?

Follow the steps below :-

Step 1:
Open Backtrack terminal and write the following:-

Code:
cd /pentest/passwords/crunch

Now to use crunch we will first move to this folder

Step 2:
Write in the terminal :-

Code:
./crunch 7 7 acbd143 -t EHF@@@@ -o EHFlist.lst

Step 3:
Enter in the above will give you the message that the wordlist has been created (when 100% is written on the terminal screen)

Step 4:
navigate to the /pentest/passwords/crunch folder and you will find the file EHFlist.lst, rename this to EHF.txt and open it and you will see the resultant words of Step 2

Explanation:-

"7 7 acbd143" - this means that the password length will be 7 charecters and it will contain the charecters a,c,b,d,1,4,3

"EHF@@@@" - It means that the passwords will contain the first three charecters same that is EHF, and the rest of the charecters @@@@ will be repeated with the charecters "a,c,b,d,1,4,3"
This will generate the while of the list.

So , using crunch you have a lot better flexibility and you have the option to make it the way you want
