Security (c) Cyber Solutions Ltd 2002

Overview

Security is a DLL component which allows encryption and decryption of any file using a password plus a deletion facility which prevents the file or the data being recovered. The encryption facility uses a unique, powerful algorithm and is extremely quick. The DLL may be referred to from any Microsoft application e.g. Visual Basic, Access VBA, Excel, Visual Interdev, FrontPage, VBA.


Setup

Run SETUP.EXE to register the DLL.  In Visual Basic, take the Project option on the menu and select References.  If you cannot see Security, use the browse button to find it. Select the check box against it so that this is ticked.  In Access open a module and select Tools / References fom the menu. In Excel use Alt-F11 to open the code window and use Tools / References from the menu.



Sample Code

Dim ss As New Secure
ss.Encrypt "c:\sacrificial.doc","computer"
ss.Decrypt "c:\sacrificial.enc","computer"
ss.DeleteFile "c:\sacrificial.doc"

The Encrypt statement creates a file in the same directory with the same name but with a .ENC suffix using the password 'computer'

The Decrypt statement recreates the old file 'sacrificial.doc' from the encrypted file 'sacrificial.enc' using the password 'computer'

The DeleteFile statement kills the file 'sacrificial.doc' and removes all the data in it so that it can never be recovered.


Warnings and Limitations:

Passwords must be limited to 15 characters.

Be careful of deleting files using this DLL - ONCE DELETED THERE IS ABSOLUTELY NO WAY THE DATA WILL EVER BE RECOVERED. EVEN NORTON UTILITIES GIVES UP!!!

DO NOT LOOSE THE PASSWORD OF AN ENCRYPTED FILE - YOU WILL NOT BE ABLE TO RECOVER IT WITHOUT IT!!!

The ENC file is slightly larger than the original - this is to hold password details and original suffix

The DLL is supplied on an 'as is' basis and Cyber Solutions Ltd accept no liability for damage or loss of data however caused.
