WinDES is the Data Encryption Standard (DES) algorhythm implemented
as a Microsoft Windows 3.x 16-bit Dynamic Link Library (DLL). Unlike
stand-alone encryption utilities which only work on existing files, 
WinDES lets you embed DES cryptography within any program capable of 
making DLL calls (C, C++, Windows-aware Basic, PAL, ObjectVision, 
PowerBuilder) to add real-time security to your data stream. Imagine 
having truly PRIVATE E-mail!

WinDES has been in use, unaltered, since 1990. It secures network 
passwords for a large Canadian insurance firm, and emulates bank
ATMs for the world's second-largest computer manufacturer. It is 
small, convenient, and FAST!

The WinDES DLL uses a 8-byte key to encode and decode 8-byte data 
packets using the basic DES Electronic Code Book (ECB) method. ECB 
is suitable for randomly accessed data, such as sectors within disk 
files. Registered users receive the ANSI-C source code to another 
two access methods built upon the DES ECB: Cipher Chain Block (CCB) 
for serially encrypting files so a single bit alteration changes the 
remainder of the file, and Cipher Feed Back (CFB) for communications 
where a single byte at a time is output instead of 8-byte packets.

WinDES is Shareware. It is free for personal, non-commerical use. 
Others may register it for $15 US for a single user (SWREG ID 3052),
or $150 US for a single Local Area Network site (SWREG ID 3196). 
A license for internal source code access and binary redistribution 
for $1000 US (SWREG ID 3197) provides the WinDES source code and the 
right to adapt and/or reuse the code in any number of company products 
as well as the right to redistribute the WinDES DLL for use with their 
products, but not the right to redistribute the original or altered 
WinDES source code without paying additional source code licenses.

There is no charge for E-mail delivery. Send a stamped, self-addressed 
envelope and a floppy disk, or enclose an additional $5 US for 
shipping via US Mail, or add $20 US for Federal Express. Allow 4 
weeks for checks drawn on US banks to clear; sorry, no Credit Cards 
or international drafts accepted. If you register via the Compuserve 
Software Registration Forum, your software will ship electronically 
the same day we are notified of your registration by the SWREG Sysop.

Even though a Singapore plant makes DES chips for AMD, and a Japanese 
manufacturer sells machines with that chip to countries on every 
continent on Earth, US federal government export restrictions apply; 
WinDES is only available to US and Candian residents - everyone else 
should just pretend it does not exist.
