How to secure your password - Things you don't know yet about your password

There are several ways on how to secure your password. Basically people use passwords base on their pet names, spouse, birthdays or any other important events and names which are alphabetically simple. On my previous post I mentioned having a seven (7) characters long password is important. In this case, having a seven characters long password is still easy to crack/decode using various method as I have mention on my previous post that it can be much easier using those tools to gain/crack passwords even if it is seven characters long.

A great way to secure your password is having a combination of alphabetical and number, more than seven characters long passwords. Base on my experience, a 7 characters long alphabetical password is cracked only in a few seconds compare to combined alphabet and number passwords. Even a longer than seven (7) characters is cracked within a minutes of waiting using a special method of cracking. Want some proof? Check out my previous post on using Ophcrack and see for yourself!

Even my twelve (12) characters long password - all alphabetical - was cracked by myself in a few minutes which I myself forcefully decided to change it having a number combination to harden the encryption. How does this happen? Having all alphabetical passwords are crack faster because of having "only alphabets" no numbers included, and a less time for decoding it. Truly, MD5 hashed passwords are hard to crack but having your passwords composed of only alphabetical is still vulnerable to cracking. A Salted MD5 hash would do because salted hash is a lot difficult to crack but on windows system is not reliable enough to protect you password.

Windows XP Cracking Passwords the Easy Way!

Well, many of us trying to crack/decode a password on Windows XP System had a hard time or shall we say most of the time we end up failure specially if we are cracking more than seven (7) characters long passwords. Some people uses cracking programs whether brute forcing, dictionary based cracking and so on. Face the fact that seven or more characters long passwords are harder to decode, possibly you can crack it for a few or more days by brute forcing.

Now we can easily crack long passwords for an instance in my personal experience I will introduce to you using the 0phCrack and the infamous "Rainbow table" algorithm. Surprisingly the seven character long or more passwords are cracked in a few seconds! Yes it's true, But bear in mind that I have my Rainbow table as big as 669 MB which it can be loaded by 0phcrack and cracks passwords in a few seconds (5 user accounts on my system with 12 characters long passwords!).

Maybe you'll think that this is just another work-today-die-tomorrow cracking tricks but to let you know that this process cracks MD5 hashes. LM and NT passwords are easily cracked by this method specially on Windows XP system. I will not discuss further as to where you can find 0phcrack and rainbow tables that I used (669MB file size) but believe me it helps me a lot, making the process done quickly as I never expected before. You can find those tools and references on many sites for free. But if you really want to know where the hell I get those tool and the rainbow table then you are free to send me pm or post your comments here.

Using this method of cracking Windows Xp password there is no need for you to reset loss password, saves your day ahead without getting caught for resetting the administrator password on windows xp. Just make sure you have the privilege to install the mentioned program/tools so that your cracking will be successful.

So start cracking now!
