Password Cracker Program

I was assigned a code by my professor and was told to improve the performance of it. The code is very raw, but I was thinking that adding a brute force code would improve the return rate of the program and come about the password at a faster rate. I just don't know how to go about implementing such a code.
The code is below.
final String GOOD_PASSWORD = "goodmorning";
          String enteredPassword = "";
          boolean passwordOk = false;
          long numOfTrials = 0;
          Random generator = new Random ( );
          int len;
          final int PASSWORD_LEN_LIMIT = 30;
          int charCode;
          boolean charOk;
          do
                    enteredPassword = "";
                    //guess the number of chars in the password 1 - 30 chars
                    len = generator.nextInt (PASSWORD_LEN_LIMIT) + 1;
                    for (int i = 0; i < len; i++)
                         //creating a number that can be used as a char in a password
                         //digits: 48 - 57
                         //upper case: 65 - 90
                         //lower case: 97 - 122
                         charOk = false;
                         do
                              charCode = generator.nextInt (75) + 48;
                              if (((charCode <= 57) && (charCode >= 48)) ||
                                   ((charCode <= 90) && (charCode >= 65)) ||
                                   ((charCode <= 122) && (charCode >= 97)))
                                   charOk = true;
                         } while (!charOk);
                         enteredPassword = enteredPassword + (char) charCode;
                    System.out.print (enteredPassword + "///");
                    JOptionPane.showMessageDialog (null, enteredPassword);
                    if (enteredPassword.equals (GOOD_PASSWORD))
                         passwordOk = true;
                    else
                         numOfTrials++;
               } while (!passwordOk);
               JOptionPane.showMessageDialog (null, "password cracked after " + numOfTrials + " trials");
               System.exit (0);
}What the program is set to do is have the computer guess the characters of the password and then have it randomly generate letters and digits in an attempt to guess what the password might be. I tried making the good password less letters (would be like having a website require a smaller amount of maximum characters in a password) and still have to go through an immense amount of trials to get it to work. Do you guys have any ideas on how I might be able to get the password to be "cracked" in a fewer amount of tries? Possibly a brute force code or something, and if so how would that be implemented.

No I wasn't trying to get this done for me. I was suggested to use a brute force code because the way the professor gave it was just insane (randomly attempt using digits, lc letters and uc letters until arriving on the correct password). Of course, using brute force method would be equally painful.
This is what I have so farimport javax.swing.JOptionPane;
import java.*;
public class LogInX
     char[] canUse = {'0','1','2','3','4','5','6','7','8','9',
                         'a','b','c','d','e','f','g','h','i','j','k',

                              int k = 0;
                              while (k < canUse.length)
                                        nextString(new Character(canUse[k]).toString());
                                        k++;
                                   int i = 0;
                                   System.out.println(s);
                                   while (i< canUse.length)
                                        System.out.println(s + new Character(canUse).toString());
                                        if (new String(s + new Character(canUse[i]).toString()).length() <= maxlen) {nextString(s + new Character(canUse[i]).toString());
                                        i++;
                         enteredPassword = enteredPassword + (s + new Character(canUse[i]).toString()) ;
                    System.out.print (enteredPassword + "///");
                    JOptionPane.showMessageDialog (null, enteredPassword);
                    if (enteredPassword.equals (GOOD_PASSWORD))
                         passwordOk = true;
                    else
                         numOfTrials++;
               } while (!passwordOk);
               JOptionPane.showMessageDialog (null, "password cracked after " + numOfTrials + " trials");
               System.exit (0); }
And even in this, I have compiled one error that I cannot find, and beyond that I am not sure if it would do what I am looking for it to do. I have a standalone brute force code that does what I was thinking (cycle through letters and digits) and I tried to piece in the bulk of that code into what I originally posted. Does anyone have any advice on fixing up the code above, or how I might be able to go about it differently? Thanks for the feedback.

SAP userid password cracking tool?

hi - can anyone confirm if SAP has a tool/utility they can use to crack a password - we have a situation where it is much easier for us if we could have them help us determine what a password is for an ALE user than changing it and aligning the new pwd is the many different places it is used.
i assume SAP has a tool for this, but not sure if they are willing to help customers w/ it.
i can see the hash code in usr02.bcode field for my user in question and could provide them that info...
thanks

As documented in [SAP Note 991968|https://service.sap.com/sap/support/notes/991968] there's a new generic password hash algorithm approach (available for all ABAP systems as of 7.02; see also [SAP Note 1458262|https://service.sap.com/sap/support/notes/1458262] on "recommended settings for password hash algorithms" for older systems).
The generic password hash algorithm is currently supporting (iterated) random-salted SHA-1 hashes.
If requested, other hash algorithms could be supported, as well. [Bcrypt|http://en.wikipedia.org/wiki/Bcrypt] (Blowfish) is currently not amongst the supported algorithms; legal aspects would need to be clarified before implementing Blowfish. On relatively short notice, SHA-256 could be offered, though.
Slow calculation might not be a disadvantage - actually SHA-1 is too fast, thus the hash calculation is iterated (preserving the password entropy) as countermeasure against brute-force / dictionary attacks.
The number of iterations, the size of the random part (bits) and the hash algorithm name can be configured for the generic password hash algorithm. Actually, increasing the iteration count and the random size is more effective than choosing a different hash algorithm. But as written above: if (for whatever reason) one feels more comfortable with a distinctive algorithm, he should submit a feature request. We'll check the feasibility to fulfill the request.

You can't get it reset; if you could there would be no point in having it. If you have an encrypted backup there are two ways this could have happened:
You checked "Encrypt Backup" in iTunes at some time in the past, either intentionally or by accident
You have a corporate MS Exchange account and your Exchange administrator installed a security profile on your phone that requires the phone'a contents to be encrypted. This, in turn, requires the backup to be encrypted for obvious reasons.
In either case you were prompted for a password the first time you backed up after whichever of these happened. So think about what you might have entered for a password at that time. Fortunately you get an unlimited number of tries. Other threads on this subject have shown that it is always a password known to the user, so it wasn't something made up by iTunes. Also, everyone who has figured it out has found it to be a different password type, so try your Apple ID password, your computer's login password, your WiFi password, your corporate domain password, etc. And try passwords that may have been changed since your first backup. As a last resort there is a professional password cracker available, but it isn't cheap - it's targeted at the law enforcement market - from Elcomsoft. There are also some scam password crackers available that don't actually work and possibly steal your information. It's likely that a developer of one or more of these will post a response with a link (possibly hidden) to their "product". So before clicking any links you might want to install the Web of Trust plugin that keeps track of scam sites and warns you. http://www.mywot.com.

How complex does my log-on password need to be?

I use 1Password to create very complex passwords for accessing websites and various accounts, but I'm wondering how complex do I need to make the password that lets me log onto my computer? In other words, is it realistic to worry about a brute force attack on my physical laptop?
Do I need an 8-digit (or more) password every time I re-start the laptop?

Who will have access to your Macbook Pro?
     Are they savvy enough to guess your password?
     Are they capable of using a password cracker to determine the password?
     Will you leave them alone long enough for them to just remove the hard drive?
How sensitive is the data on the Macbook Pro?
     Is it so sensitive that you need to encrypt the entire hard drive?
If someone steels your laptop, you can't create a password strong enough to keep them out unless you encrypt it. You just pull the hard drive and mount it on another system. If it is not encrypted, you can do whatever you want with it.
If the above leads you to believe you need to encrypt it with FileVault, that password better be very good.
Your account password (if not used to decrypt the drive), can be as simple or complex as you need to thwart the first part, above.

Password recovery on Cisco AP 1232

Hi all.
I have a Cisco 1232 AP at a remote location. It was configured by somebody no longer with the company and I have no passwords for it, no do I have a back up config.
It is using local authenticaiton.
Is there a way to do a password recovery without losing the current configuration?

My appleid is not recognizing my password! I've reset it several times already!

This is very frustrating! I have set up my apple account, etc and everytime I try to sign in with my appleid, it's not recognizing my password! I've already reset my password several times to accommodate the stupid error! Someone please help!!

If your son continues to have admin access, it means that he has unrestricted access to the password after you change it.
Another accessible admin account was mentioned.
He has put his user id in the /etc/sudoers file with root access.
You keep the password in a text file in your account. He has changed the access permissions on that file, so he can read this from his account. Similarly, you keep the password someplace that is no longer secret.
He or a sibling has distracted you with conversation while watching your admin keystrokes.
His own keystroke logger tracking what you type, or freely downloadable password cracking software.
You choose passwords that are simple for you and may be readily guessable family, pet, or household object names, birthdates, etc. Choose something that is off his guess radar. A name of something unique before he was born.
You hope he hasn't shared the admin password with someone outside the home.
Some ideas for you. Discipline isn't taking away the computer, it is temporarily taking away other privileges perceived as more valuable, if the password intrusions do not stop.

View Password hash in Active Directory

Hi all
I am the administrator and i want to view the password hashes of the users in Active Directory. Please tell me how i can view the password hashes of the users. Where are the password hashes of the users stored in Active Directory.

Hi,
Before going further, let’s clarify how Windows store password.
Instead of storing the user account password in clear-text, Windows generates and stores user account passwords by using two different password representations, generally known as "hashes." When you set or change the password for a user account to a password that contains fewer than 15 characters, Windows generates both a LAN Manager hash (LM hash) and a Windows NT hash (NT hash) of the password. These hashes are stored in the local Security Accounts Manager (SAM) database (C:\Windows\System32\config\SAM file) or in Active Directory (C:\Windows\NTDS\ntds.dit file on DCs).
You can force Windows to use NT Hash password. For detailed information, please refer to the following article.
How to prevent Windows from storing a LAN manager hash of your password in Active Directory and local SAM databases
http://support.microsoft.com/kb/299656
After you configure Password History, Active Directory service will check the password hash stored in AD database to determine if user meet the requirement. Administrator doesn’t need to view or use password hash.
Regarding the security of password, the following article may be helpful.

Is there a Word Doc password retreiver for MAC iOS?

I have a Microsoft Word document which I added a password too and now its saying the password is wrong, which is wrong! I know the password, i even wrote it down so I would not forget. All the password crackers I find on google are geared to the PC, is there one for the MAC?

I have not seen a Microsoft Word password cracker for the Mac.

Database - 9i - password recovery

Hi, After the installation of Oracle 9i, i set the passwords for accounts SYS and SYSTEM which i couldn't guess now. Is there a tool/script to recover the set passwords? or can i find any notepad files where the passwords are written?
Help please...

There is no way to recover the passwords, at least not without running a password cracker.
Assuming you can log in to the operating system as the Oracle user (Unix) or as a user in the ORA_DBA group (Windows), however, you should be able to
sqlplus / as sysdbato get in to the database. Once in, you can change the passwords for those accounts.

What passwords will a Verizon e-mail account accept?

I'm a new FiOS Internet customer and I saw that e-mail passwords have to be at least 6 characters, including one letter and one number. OK, so I can't use the password I used on my old account.
But when I chose a password composed of an English word plus two numbers it was rejected as too easy to guess.
Then I chose one composed of a foreign word plus numbers. It, too, was rejected for the same reason!
(At this point I want to mention that I once saw network correspondent John Roberts at a computer equipped with a password-cracking program and it guessed his password in a few seconds, and the password was "konnichi-wa" ("Good morning" in Japanese).
Still, my 2nd rejected choice should have been as unguessable as my final choice (which I won't hint at here)
Solved!
Go to Solution.

This is from Verizon's Help page:
Password change tips
Your password should be case-sensitive.
Use a combination of at least six numbers and letters.
Don't use your user name in any form (e.g., spelled backwards or with a number added to the beginning or end).
Avoid using a single word, from any language, with a number added to the beginning or end.
Your password cannot include such characters as /, #, *, or a blank space.
Please allow up to one hour for your password change to take effect.
Also:
It cannot be too simple. (passw0rd, abc123, etc.) - These are FAR too easy to guess.
It cannot contain your username or your first or last name as they appear in Verizon's system. (This means that if Verizon has your name as J Smith instead of John Smith, then your password can't have a 'j' in it!)
Hope this helps! If I remember/stumble across any other rules I'll let you know.

If someone steal files that contain master password and website username&password ....

can he/she decrypt those files and get my website user name and password??

It depends on the strength of the master password.
There are programs available to crack passwords, a common method used is either brute force or dictionary attacks. If you have a weak master password, such as a word, password cracking applications will probably be able to crack the master password, giving somebody access to your other passwords. If you use a strong master password that contains a mixture of upper and lower case letters, numbers and other characters, it will be very difficult to crack, and will likely take a prohibitively long time.

Tried veriface, now the laptop wants a password.

Hi.
I tried veriface on my G570, but found it annoying so I uninstalled it. Now when I turn on the laptop it asks for a password at the start up screen. This laptop was sent to Lenovo to be repaired a few months ago, where they reinstalled windows 7 and made me a generic default user account WITH NO PASSWORD.
1. Pressing esc or enter at the login screen does not work.
2. I cannot get into any of the safe modes as it still asks for this non existent password.
3. I've tried resetting to last known good configuration, doesn't work.
4. Trying to repair the windows installation asks for the password.
5. Tried setting up passwords in BIOS, doesn't work.
Any help please?
Solved!
Go to Solution.

it's not a security question.
it was a password.
If you don't have a Windows password, Veriface asks you to type one in before it allows you to mess with the facial recognition.
it's just a plain box, and when you typed it, it showed asterisks.
how long ago was this? forgot already?
if you don't remember, you're going to have to use a password cracker (I don't know which one works), or restore the laptop to factory condition.
The good news is, if you have a desktop computer, you can remove the hard drive and plug in a sata cable and recover your files before you reformat to factory image.
i think this is what it looked like....

HT203271 forgot iphone backup password how to recover

how to recover password or reset to recover backup

Without the backup passcode the only option is to restore the phone and set it up as New. You get unlimited guesses for the passcode, so you might try a bunch of passcodes that you have used in the past. And to speed up the process just uncheck "encrypt backup" in iTunes and you will be prompted immediately for the passcode.
Elcomsoft makes an iPhone backup password cracker that will work if you are not in the habit of using strong passwords. It is targeted for law enforcement use, and priced accordingly. However, they have a trial version that will give you the first 2 characters.
