crunch (included in BT5) can easily do this for you.

Thanks for your answer. I've the last question for you guys. Since i will go abroad for an year, will be some possibilities to "have" an internship? (to improve quickly my skills) Or my skills of "bachelor" are not enough to start an internship? (of course in the field of IT security)

thapnk you again-

cyber.spirit - Please don't take this rudely (it's not intended as such)

aweSEC gave you what you want.  In the time you've waited for it, you could easily have scripted a tool to generate your list.  I mean, you originally asked 5 days ago...

missing the point Cyber.Spirit.  Eventually we just want a site to work and do what we need it to do without having to worry.  Hosting a full site when you just want to write a regular blog is overkill by today's standards.  Even with free sites, you still need to worry about maintenance, whether you do it or the host does it.  Most of my site is maintained by the host but there are pieces that fall to me to manage and can be exploited if I don't keep up on it.  If I just want to post to a regular blog, it is much easier to sign up for the free Blogspot account.  That way I can tweet my thoughts and concerns and reference the blog for more content that can't fit in the standard twitter post. 

Also one thing I find great about maintaining a blog is the writing practice.  As you go further in your Security career, you will find this becomes a must have skill.  It can eventually lead to possibly doing talks at the local Bsides event, SchmooCon or DerbyCon.

I remember EFS used to turn the folder title green. Much more subtle is having a hidden folder with no name and a background color icon..

If you're doing this freqeutnly, I'd tke a look at hashcat (http://www.hashcat.net).  It has the ability to do a mask attack, and you can easily setup brute lists with just numbers using the masks.  This saves disk space when you want to enumerate over large groups in a static pattern.
