DES-56bit En-/Decryption

Functions to make passwords for .htaccess based Web-Site protection, and en-/decryption of whole files. This library is based on sources found in the Internet and the DES56 algorithm itself is under the license GNU GPL v2, see subfolder DES56-Crypt\license. However, my implementation of the QB64 wrapper library is Public Domain.
