This application will quickly and fairly securely encrypt or decrypt any document you drop on it. It will handle files of an unlimited length, and will use as much memory as you care to give it — i.e. allocating more memory will speed it up (slightly).
USAGE:
To use QuickEncrypt, either drop any number of files onto the application, or start it as usual by double-clicking on application. For each file, if it isn’t encrypted you will be prompted for a password use to encrypt the data, which will be confirmed to ensure you didn’t mis-key it, since there is no way to unencyrpt a file if you forget the password. If the file is encrypted, you will be asked for it’s password, and given up two four attempts to get it right.
When you have entered a valid password, the file will be quickly encrypted or decrypted, with a progress dialog reporting how things are going (though for anything but huge files it will flash by very quickly), then you will be returned to the Finder™ It’s as easy as that.
COMPATIBILITY:
This application requires System 7.0 or greater. It should work on all machines that support System 7 (i.e. the Plus upwards).
WARNING & DISCLAIMER:
Note that while the encoding schemes are fairly secure, I do not guarantee they are unbreakable. I accept no responsibility for any effects of the use of this program. I have tried to make the schemes secure, but given sufficient motivation, skilled low level hackers can break almost all forms of security. Use at your own risk.
Note also that only the data fork of the file is encrypted — in the unlikely event that there is any sensitive information in the resource fork, it will not be protected. This should not be a problem.
Warning: do not forget your password!

This program is being released as Freeware. You may give it away to anyone, provided you include this document with the software, and both are unmodified. Since it’s not Shareware, you may continue to use it without paying me any money, however if you’ve found it useful and want to donate something, I wouldn’t turn you down!
If you come across any bugs, please let me know. Rest assured I have checked it quite extensively, and found it works fine on my machine and those of my Beta Testers, but I accept no responsibility if it trashes your hard disk or blows up your Mac.
