Advanced Encryption Package 2003 Professional. Typically you encrypt files because you don't want others to see them, but sometimes you want to send someone an encrypted file. Most if not all encryption programs allow you to do so--they vary, however, in terms of how difficult the process is. AEP2002's most noteworthy feature may be its flexibility: Not only can you encrypt files for your own protection but you can easily create "self-decrypting" versions of your files that others can run without needing AEP2002 or any other software. The program includes a file shredder that wipes the contents of your original files. It also integrates nicely with Windows Explorer, allowing you to use Explorer's context menus and avoid having another window clutter your screen. It also uses military grade encryption for protecting your private files. Program supports strong encryption algorithms: DESX 128, Blowfish 448, Rijndael 256 (Now it is Advanced Encryption Standard), CAST 256, Triple-DES 192, RC2 1024, Diamond 2 2048, Tea 128, Safer 128, 3-Way 96, GOST 256, Shark 128, Square 128, Skipjack 80, Twofish 256, MARS (IBM) 448, Serpent 256. AEP2002 Pro supports skins technology and has 10 nice additional skins! Moreover program has full support for ZIP files! I.e. ability to add files into .ZIP file, browse and extract contents from .ZIP file. Compression rate is better than WinZip's one! Plus Complete support for Command Line Interface.
