Hello! Since there are no need for docs, this read-me file should do it. TIPS ~~~~ 1 - Compress you file BEFORE encrypting it, if you will want to have the benefit of compression. Encrypted files are NOT compressible... So do-it BEFORE! 2 - Use LONG passphrases, since the security of a good crypt algorithm depends on the passphrase and its length. This program can have passphrases up to 576 bits... Use it! 3 - The original file is still on your disk... If that is NOT in your idea, then use Norton Utilities to Erase the file and every non used disk space... You may have data residues somewhere on the disk, and certainly on RAM. It's upon you those other circumstances of a tight security 4 - To increase even further your passphrase safety you may then COMPRESS your files. Compressed files are very much like encrypted files except for the header, but even if BLW-CBC hadn't be implemented the in CBC mode the result would still be VERY effective! WARNINGS ~~~~~~~~ 1 - By default, the output file AS the very same name as the original but a different extension.... MEANING: IF Enciphering Many files with the same name name in common will overwrite the previously encrypted file... SOLUTION: If you want to encrypt many unique-name files USE an ARCHIVER or a COMPRESSOR that allows MULTI-FILE inside. 2 - If you forget the name of the file you encrypted, then you have lost that info... MEANING: The only info allowed to the peeker are the Extension and the Size of the original. SOLUTION: Use a COMPRESSOR like RAR, ARJ, ZIP or LHA... your info will be inside, protected and you will save disk space. That's all... Enjoy this free program... and try to watch a little less TV... There is a wonderful world outside... Our world! Cordially, Dutra Lacerda
