Quick:CRYPT v2.0 - putting encryption one click away

Copyright  1998-1999, littleBIGSoftware. All rights reserved.

About
=====

This software integrates powerful file encryption into Windows 95, 98 and NT. Right-clicking allows the selected file(s) to be encrypted and decrypted using the password you specify. During encryption, the file(s) can optionally be compressed. Use of the Blowfish encryption algorithm, as well as a random 'salt' value, gives you the security of unbreakable encryption*. Use of the RIPEMD-160 hash algorithm ensures the encrypted file can only be decrypted with the correct password.

*All encryption algorithms are open to a dictionary or brute force attack. Choosing a sufficiently long password using upper and lowercase letters, numbers and punctuation marks will render these forms of attack infeasible.


Installation
============

Please run the enclosed SETUP.EXE. This will copy QuickCrypt.DLL to your windows\system directory, and make the necessary changes to your Registry.


Un-installation
===============

Please run the Uninstall program located in the Quick:CRYPT folder. This will remove QuickCrypt.dll and undo all changes made to your registry.
