Introduction. --------------------------------------------------------- Jetico, Inc. company designs and develops data protection systems for IBM-PC compatible computers. Our products: BestCrypt+, BestCrypt, BestCrypt NP has a reputation as relaible, easy to use and powerful products providing a user with high level of data security. The BCWipe utility is a part of the BestCrypt NP data protection system. BCWipe software is intended to give you a confidence that your deleted files will not be restored by any intruder. Jetico, Inc. company will be glad if BCWipe utility helps you in your work (http://www.jetico.sci.fi). 2. Why do you need a wiping utility? --------------------------------------------------------- When you delete your sensitive files from a disk on your computer, operating system (Windows 95 or Windows NT) does not erase these files contents from the disk - it only deletes 'references' on these files from some system tables. Contents of the deleted file (or file's 'body') continue to be stored on the disk and can be easily restored using any disk tool utility. You should also take into account the problem of so-called Windows 'Swap' file. Swap file is the Windows system file that is used for the virtual memory support. The size of this file changes dynamically, and it can temporarily store the parts of files or other information. When you open your secret document, Swap file can be used by system to store a part of the document. What is wiping? A "wiping" term is used here to call a process of shreding a contents of a file or a free disk space. It will be impossible to restore the data stored before on the disk or in the file if you run a wiping utility. BCWipe utility provides 3 ways to shred files' contents from the disk when you delete your sensitive files: a. Delete with wiping. Using 'Delete with wiping' command you can delete and wipe your files and folders from Windows Shell (Explorer program); b. Wipe free disk space. If you have deleted sensitive files using standard operating system command, you may wipe free space on the disk where these files were stored - all previously deleted files' contents become erased; c. Swap file wiping. BCWipe utility automatically wipes Windows Swap file contents when you run 'Wipe free disk space' command. 3. How to install BCWipe utility --------------------------------------------------------- Setup program copies all necessary files to your hard disk and inserts all needed lines into Windows 95/NT Registry database. BCWipe Utility Setup program uses a standard way to install software and provides all necessary explanations of installation steps details. The only default information user may want to change during installation is the Directory name where to place the BCWipe Utility. All dialog windows of the Setup programs are like each other and have the following buttons: Cancel - click this button to abort installation Next - click this button to proceed installation Back - click this button to return to previous step of installation NOTE: BCWipe Utility Setup program writes also an information to Windows Registry database, places dynamic load liblaries to WINDOWS\SYSTEM directory, prepares a file for uninstall procedure. Please do not make any manual manipulations to install or uninstall BCWipe Utility software to prevent appearance of unused garbage software on the system directory or unused strings in Registry database. 4. How to run BCWipe utility --------------------------------------------------------- You can run BCWipe utility from Windows Shell (Explorer program). After installation of BCWipe utility you will find "Wipe free space" and "Delete with wiping" commands in the context menus of the Explorer program. You can call a context menu by pressing right mouse button on the drive you would like to wipe or on the file (folder) you would like to delete. You will need to choose the option for wiping your disk: Normal or U.S. DoD. U.S. DoD wiping is enhanced shredding process to match U.S. Department of Defence recommendations (DoD 5220.22-M). DoD wiping is useful if you assume that your computer disks may be investigated with a special equipment. In other cases choosing of the Normal wiping option will make your free disk space useless for curios hackers. NOTE: Before running "Wipe free space" command on the disk it is recommended to close all apllications. There are at least two reasons to do this: - some programs create temporary files and the contents of this files will not be wiped when you run "Wipe free space" command; - Windows swap file (or pagefile) may store some sensitive information that is used by currently loaded applications. This part of swap file will not be wiped. 5. How to run BCWipe utility from the command line prompt. --------------------------------------------------------- You may run BCWipe commands to wipe free space on the disk and delete files or folders with wiping from the command line. This feature of the BCWipe software allows you to insert wiping commands to your BAT files and then run this BAT file automatically using Windows 95 SystemAgent or other sheduling software. BCWipe Setup program installs BCWipe.exe program to the target directory which you have choosen during installation. To run BCWipe command to wipe free space on the disk you should run BCWipe.exe by the following way: > BCWipe <FreeSpace> [-<Mode>] <drive name> For example: > BCWipe.exe FreeSpace -DoD C: To run BCWipe command to delete files or folders you should run BCWipe.exe by the following way: > BCWipe.exe <Delete> [-<Mode>] <file or folder name> [<file or folder name>...] For example: > BCWipe.exe Delete -Normal C:\\SecureDate.doc In both cases the optional field <Mode> may be: DoD - the U.S.DoD (5220.22-M) seven pass extended character rotation wiping Normal - two pass standard wiping ATTENTION: If you run BCWipe.exe with the field <Mode> set to "DoD" or "Normal", the BCWipe utility will run without asking any additional confirmation for deleting files and for wiping free space on the disk. Be careful to run the utility using this way! It will be impossible to restore files' contents after this operation! 6. Known problems --------------------------------------------------------- If your computer has more than one disk, BCWipe utility correctly defines what disk contains Windows swap file for Windows 95 computers. On Windows NT 4.0 computers the file 'pagefile.sys' usually is on the disk where operating system have been installed. If you did not change this default configuration for your pagefile, BCWipe utility will work with the pagefile correctly. If you have manually moved your pagefile to other location, you should take into account that BCWipe utility may not correctly report you about a pagefile location. Besides of this incorrect drive letter report BCWipe utility will work with Windows NT 4.0 pagefile correctly. This problem for Windows NT will be solved in the nearest future. 7.
