Quick:CRYPT v1.0 - putting encryption one click away

Copyright  1998, Stephen Darlington. All rights reserved.

This software is FREEWARE. Please read the license carefully.


About
=====

This software integrates powerful file encryption into Windows 95, 98 and NT. Right-clicking allows the selected file to be encrypted and decrypted using the password you specify. 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.
