I forget passwords alot and now I can't do anything for I my computer want's my password to do most things. Anyone have a program that can type A then a and so on.
I really want to play my games.

[Schilcote]

Well, if you've locked yourself out of windows there's things to help with that (but use your powers for good, not evil).

If you've locked yourself out of a game that takes a password to allow you to play (Never heard of such a thing, but then I only play a couple games) you might contact the developer about it and see if there's a backdoor. If you've locked yourself out of Steam, same thing.

If you're lying and you just want to be an Uber 1337 haxor, go away script kiddie.

Keep in mind that a brute force script can take years if it's a complex password.

Also, who forgets their passwords?  I have a set of passwords I use for everything.  If I forget one, I just go through all of them until one works.

It's not complex. I forgot the admin password and some of my games require I have admin access. All brute hack scripts search lead to bugged sites.

[Dasleah]

Well now, this depends entirely on the complexity of the password. Does it contain both uppercase and lowercase letters? Numbers? Symbols? How long is the password?

We were having this conversation on /g/ last night. Some script kiddie wanted to break a 20 character long password that contained only letters (uppercase and lowercase) and thought he was hot shit using 60 computers at once to do the cracking. The math worked out to be it'd take him the region of a couple billion years to get it. Using just one computer would mean he'd have to calculate past the heat death of the universe.

All uppercase and between 6 to 12 letters.

So half that to a quarter.

500 million years or one billion.  Have fun.

I don't care if it takes that long I need script first.

[Aqizzar]

So you don't remember your admin password.  How often have you typed it in before?  Do you have a standard set of stuff that you reference when making passwords?  Do you remember what you were thinking of when you made it?

Trust me, wracking your brain for the code is going to work a Hell of a lot faster than hotboxing your way in.

[Schilcote]

If you're brute forcing it. Now, you say you want you're computer's admin password? If you're using Windows, I happen to have just the right thing. It's a little boot disc that worms its way into the SAM files and allows you to reset passwords, as well as re-enable disabled accounts (such as the default Administrator account) and upgrade permissions. Just slip it into your disc drive and reboot. I'll find it in a second...

EDIT:

Ok, so you say you forgot your Windows administrator's password, huh? Oh well, it doesn't really matter if you did or you just say you did. The fact is that you need to gain access to a computer and you cannot "remember" the administrator's password.

You just write that ISO to a disc, then slip it in and boot off of it. Piece of cake. It works on everything Vista and earlier, don't know about later versions because I haven't tried it.

[Dasleah]

The age of the universe in seconds is 4.4 x 10^17.

If you were to calculate one password per second (which is a wild underestimate) then it'd take you 1.3737055196745938 x10^29 seconds at most to crack that thing.

Spoiler (click to show/hide)

my math may be wildly off because i asked the internet to calculate it for me

You don't seem to understand. Randomly guessing the password through brute force or rainbow tables isn't going to work. If you owned a billion machines making a billion calculations a second it'd still take years - decades - for it to get the password. You aren't getting in this way.

Since it's an admin password for Windows it's making me more and more suspicious that you're doing this for reasons other than a game. I doubt it's even your own computer.

[G-Flex]

More than that matters. There's also the strength of the password to consider.

If Windows is storing a legacy LM hash (old LANManager crap, it's really bad), and you can do it that way, brute-forcing is hilariously simple.

There are definitely tools to recover a Windows admin password, but I'm honestly not sure what's out there that's decent and legitimate.

So half that to a quarter.

500 million years or one billion.  Have fun.

That's not how math works. A 10-character passwords takes EXPONENTIALLY shorter time to crack than a 20-character password. Same with case-sensitive vs. all-lowercase.

Let me put it to you this way.

Say you have a 10-character password, and you want to consider all uppercase and lowercase letters.
Numbers of possibilities = (26*2)^10 = 52^10 =144,555,105,949,057,024
But what if you know they're all lowercase?
Number of possibilities = 26^10 = 141,167,095,653,376

So it's not 1/2 the possibilities, it's 1/1024 the possibilities. There's a big difference between 2 and 1024.


Now let's compare the difference between a 20-char long, case-sensitive password and a 10-char long, only-lowercase password.

(52)^20 = 20,896,178,655,943,101,411,324,274,803,736,576
(26)^10 = 141,167,095,653,376

One is 148,024,428,491,834,392,576 greater than the other.


For a 10-character-long password, only lowercase, brute-forcing still takes a hideously long time.

Probability of any given password being wrong: ((26^10) - 1)/(26^10)
Probability of you never getting it right within N tries: [((26^10) - 1)/(26^10)]^N

So for a 50% chance to have gotten it right:

[((26^10) - 1)/(26^10)]^N = 0.50
N ~= 100,000,000,000,000

At 50 tries per second, that's about 63,419 years. Still a damn long time, but certainly not 500,000,000,000.


Now, if you do 50 tries per second on 50 computers, just as an exercise... that's (50*50) = 2500 tries per second. At this rate, it's only a little over a millenium! (about 1268 years).

Of course, my numbers could be off. 50 computers trying 10000 times per second might do it in your lifetime. If you're lucky.



Again, this is just straight brute-forcing. Rainbow tables are something completely different, and one may exist, and if the computer is storing an LM hash of the password, and you can use that, then all bets are off, because those suck beyond belief.

[The Scout]

That is the time for it to finish not to find the password. It would probably take alot less time because the password is probably 8 letters long.

Brute forcing the password isn't going to work. Period.

Can anyone figure out another way?
