Unauthorized copying or distribution of Wdcrak is a criminal violation of Federal Law. Copyright c by John E. Kuslich 1994. All rights reserved. Version 1.5 Monday 24 April 1995. 1) Installation Wdcrak will install itself. Just insert the diskette in the a: or the b: drive and type A:setup or b:setup as appropriate. Wdcrak will not alter your autoexec.bat or your config.sys files. No .ini files are created nor are any .ini files altered. Wdcrak does add some files to your windows/system directory however. These are Visual Basic runtime files needed by the program. They are vbrun300.dll and others. Be sure to install Wdcrak only in the following directory: C:\wdcrak. 2) Use License You are authorized to use Wdcrak on one computer at a time. You may not install Wdcrak on a network or on multiple computers so that more than on user could use Wdcrak on more than one computer at a time. Site licenses are available for a fee. Contact CRAK Software for details. You may make copies of WDcrak and distributes them to others provided that you do not reveal the security code necessary to access the full features of the program. You must, however, distribute the software in its entirety including these instructions (minus the security code). 3) Opening Display Click on the Wdcrak icon and start the application just as you would any other Windows application. If you have purchased the full capability version of Wdcrak, you may enter the security code to enable Wdcrak. Be sure to follow the instructions given with the security code exactly, using the proper letter case as described. If you do not know the security code, Wdcrak will only reveal passwords of exactly ten characters. Simply click on the "Don't Know" option button to start the program. 4) Selecting a File Wdcrak uses standard Windows dialog boxes to allow you to examine and select any file on any disk in you system. Select the appropriate disk, then the proper directory, and then click or double click on the file you want to crack. 5) Exiting Wdcrak Wdcrak may be exited at any time simply by clicking on the "Exit" button in the lower right portion of the display. 6) Wait for Processing Unfortunately, Wdcrak must do an enormous amount of processing to collect file statistics and determine the encryption key used. Please be patient. The Horizontal scroll bar at the bottom of the Wdcrak window will continue to slide back and forth as processing continues. 7) Check the Decode Grid *****VERY IMPORTANT***** It is vital that you check the text appearing in the decode grid when the program pauses and puts up a message box. . Usually there is absolutely no need for correction and the user may then simply click on the "Find Password" button the get the password. Sometimes Wdcrak cannot exactly determine the decode key on the first pass and needs your help. Click on the "OK" button first and then use the vertical scroll bar at the right to examine the decoded text. If there are obvious errors such as Capital letters where none belong, or there are nonsense characters in certain positions, simply use the mouse to click on the cell that is wrong and type the letter you think should be there. Remember, use the proper case. Notice that when you type in a new character, all the characters in that column of text also change to other characters (not what you typed). If all the characters in the column you have changed look correct, then go on and correct the next column. It is kind of like solving a big crossword puzzle only very much easier because the vertical scroll bar allows you to see so much text and the text becomes more and more readable and obvious as each correction is made. Sometimes all of the text in a particular column looks correct except for one nonsense character. This is probably a formatting character (Tab etc.). *******DO NOT CORRECT THESE FORMATTING CHARACTERS****** if the rest if the characters in the same column seem to be correct. In the case where the grid comes up completely blank, there is no need for corrections. The program has found a section of pure key which it likes to turn into spaces. The rest of the text may be garbage but it doesn't matter. Click in the "Find Password" button and the password will magically appear! 8) Click On the "Find Password" Button Ta Da!!! The password will appear. A nice surprise appears also. Our founder (Head Geek) is very proud of his hat and bandanna!!! 9) Extended Features If you are trying to recover a password from a file which is heavily formatted, uses a wide selection of fonts, or has a lot of embedded graphics WDcrak may not find the start of text (which it needs) properly. In this case grab the vertical scroll bar and slide it down a little bit, then click on "Find Password". Keep repeating this procedure and monitor the "Text Quality" number displayed just below the vertical scroll bar. Generally, the lower this number the better. If the "Text Quality" number is less than about 85, you will be able to reconstruct the displayed text enough to finally recover the password by clicking on the "Find Password" key. Wdcrak searches for key in the area of text starting with the seven lines displayed on the grid. By sliding the vertical scroll bar you can pick the area of the file you wish to search. The search length is determined by the value you set in the "Search Length" box. Values of search length between about 25 and 200 are optimum, but certain very long files may require longer (and more time consuming) searches. Important... Be sure to correct the grid text before each click on the "Find Password" key after the search length has been altered. 10) Limitations Wdcrak requires standard English text for proper decoding of files. If the file is not more or less standard English or have the frequency distribution characteristics of standard English, Wdcrak may fail miserably. The password recovery algorithm is surprisingly robust however, so go ahead and click on the "Find Password" key. The password recovered may still be correct! We are sorry if the program fails...there are no guarantees or warrantees of any kind either expressed or implied for Wdcrak. Use the program at your own risk...it may fail to find your password. 9) Purchasing Wdcrak Send $99 Payable to CRAK: CRAK 2901 E. Greenway Pkwy. PO Box 31844 Phoenix, AZ 85046-1844 John E.
