===================================================================== ===== FILE LOCKER version 2.3 ===== ===== November 16, 1993 ===== ===== ===== ===== by Rodney M. Savard All Rights Reserved ===== ===================================================================== File Locker is a Microsoft Windows based file encryption program. It has the ability to encrypt multiple files at a time, and can also run "in the background," letting you do other things in Windows while it is encrypting files. This program is shareware. Register it by sending $10 to: Rodney M. Savard 4507 South Kent Street Kennewick, WA 99337-4510 For registering, you will receive a registration number that will uncripple this shareware version plus all future versions. Once registered, File Locker will no longer display the registration information that shows when you run the program. INSTRUCTIONS ON USE: ==================== Run the File Locker program either by using the FILE-RUN command in Program Manager, by double clicking on the LOCK.EXE file in File Manager, or by double clicking on the File Locker icon in Program Manager. (For instructions on setting up an icon in Program Manager for the File Locker program, see your Windows documentation.) When you run the program, you will first see a registration information screen. (Unless you have registered your copy of File Locker.) After five seconds, two buttons will appear: one labeled "I'll Do It Later..." and the other labeled "Register Now!". Pressing the button "I'll Do It Later..." will take you to the next screen--the File Locker program. If you press "Register Now!", you will be prompted for a registration number. (You will receive a registration number after registering File Locker. [see above]) Encrypting a File ----------------- To encrypt a file, type the name of the file that you want to encrypt into the SOURCE FILES text box. Then click on the "LOCK FILES" button. You will now be prompted for a locking phrase (or password). You can pick any password you want, as long as it's not more than 10 characters. Type the password into the LOCKING PHRASE text box. (Question marks will appear as you type it in.) Now verify that you typed in the password correctly by entering the same password into the VERIFY PHRASE text box. If the passwords in both text boxes match, you can press the button labeled "Encrypt" to encrypt the file. If the passwords in both text boxes do NOT match, then you will not be able to press the "Encrypt" button. File Locker will now encrypt the file, showing the percent completion in the Bar at the bottom of the File Locker screen. NOTE: This program is relatively slow in encrypting and decrypting files. If you want to encrypt a rather large file, I recommend turning on the "Background Execution" option. (Described below.) This will allow you to do other things in Windows while File Locker is busy encrypting the file. Decrypting a File ----------------- This is done in the same way you Encrypt a file. First type in the name of the encrypted file in the SOURCE FILES text box. Next, click on the UNLOCK FILES button. You will now be prompted for the phrase (password) that was used to encrypt the file. You MUST enter the same password before File Locker will decrypt the file. (NOTE: The password is not case sensitive, so File Locker considers "PASSWORD" and "PassWord" to be the same.) When you finish typing the password into the LOCKING PHRASE text box, press the "Decrypt" button. If the password you typed in and the password that was used to encrypt the file match, File Locker will decrypt the file, showing the percent completion in the Bar at the bottom of the File Locker screen. Other Options ------------- - You may encrypt more than one file at a time by typing each filename, separated by a space, in the SOURCE FILES text box. For example, if you wanted to encrypt the file C:\TEST.TXT and C:\FILES\REPORT.WP, you would type the following into the SOURCE FILES text box: c:\test.txt c:\files\report.wp You may encrypt up to 200 files at a time. When you press ENCRYPT FILES to encrypt multiple files, you will only be prompted for a password ONCE. That password will be used to encrypt all of the files in the SOURCE FILES text box. You may also decrypt multiple files the same way you encrypt multiple files. You will only be prompted for a password ONCE, and that password will be used to decrypt all of the files in the SOURCE FILES text box. - You may specify wildcards in the SOURCE FILES text box. For example, to encrypt all of the files in the C:\TEMP directory that have the extension TXT, you would type the following into the SOURCE FILES text box: c:\temp\*.txt This method can be used for decrypting files as well. - Pressing the button labeled "Tree..." will bring up a directory tree. You may select the file you want to encrypt/decrypt on this screen. This form works similar to other File Open Dialog boxes in Windows, except that you can select more than one file. To select more than one file in the directory tree, hold down the CTRL key while selecting the file names. Pressing "OK" (or ENTER) will return you to File Locker and place the file names you selected into the SOURCE FILES text box. Pressing "Cancel" (or ESC) will return you to File Locker without placing the file names you selected into the SOURCE FILES text box. Pressing "Scan Directory" will search the current directory for encrypted files. This feature is only availabel when you register File Locker. - By clicking on the OPTIONS menu in File Locker, you can configure File Locker whether or not it should run in the background, and how it should notify you when it finishes encrypting/decrypting files. When "Background Execution" is checked, File Locker will let you do other things in Windows while it is busy encrypting/decrypting files. If "Minimize on OK" is checked, File Locker will be reduced to an icon when it starts encrypting/decrypting files. If "Restore on Completion" is checked, File Locker will be restored (un-Minimized) when it finishes encrypting/decrypting a file. Selecting "Notify on Completion", you can tell File Locker how you want to be notified when it's finished encrypting/decrypting files. If "Do Not Notify" is checked, File Locker will do nothing to tell you that it's finished encrypting/decrypting files. If "Notify With Beep" is checked, File Locker will cause a System Beep when it finishes encrypting/decrypting files. If "Notify With Dialog" is checked, File Locker will cause a Dialog Box to pop up, telling you that File Locker finished encrypting or decrypting files. - The configuration of File Locker is saved when you end the program. The configuration is kept in a file named "LOCK.INI" located in your WINDOWS directory. DOS Based File Locker (DOSLOCK.EXE): ==================================== This DOS based File Locker program can be run when you are in DOS. This is useful if you want to decrypt or encrypt a file without having to start Windows. To run this program, type DOSLOCK at the DOS prompt. (NOTE: This version of DOSLOCK does NOT accept any command-line parameters.) You will be asked whether you want to (1) encrypt a file, (2) decrypt a file, or (3) exit. Type your choice and press ENTER. Now enter the file name of the file you want to encrypt or decrypt and press ENTER. (NOTE: You CANNOT list more than one file or use wildcards when specifying the file name.) Now enter the locking password and press ENTER. (NOTE: The password will NOT be echoed onto the screen as you type it in.) Enter the password again to verify that you typed it in correctly, and then press ENTER. (NOTE: If you are decrypting a file, you will not be asked to verify the password.) The file will now be locked or unlocked. ===================================================================== If you have any questions, comments, problems, or suggestions, I would love to hear them!
