Encoding Decoding Free Portable isn't the easiest file locker to use, but it offers plenty of strong features. Its major downfall is that the files only work inside of this program once they're locked. You'll probably be fine with this once you see all the program can do.
Since this is a portable program, there's no installation needed and you can take it with you on a USB drive. The program supports regular file importing and drag-and-drop importing, too. Even though its layout is something out of a '90s sci-fi film, don't mistake it for a cheesy program. Encoding Decoding Free Portable offers full encryption and decryption in seconds. When you're locking a file, it will give your password a score so you know just how easy it would be to guess. The only downside is that the program uses a proprietary format to lock things. If you decide not to use it any longer, all of your locked files will stay locked forever. Its powerful encryption and ease of use are enough for you to keep it around, though.
Encoding Decoding Free Portable offers one of the best ways to lock down your files. The fact that it's portable and can go wherever you go is just icing on the cake. Just make sure your friends and family use it if you're sending them sensitive files under lock and key.
From Marcello Pietrelli e Gianni Baini:
Encoding Decoding Free Portable is an application that offers you to encode and decode any type of file. Be used to hide all the sensitive and important data that we want to keep away from prying eyes. It features coding of any type of files, integrating windows explorer to explore more rapidly, creating one password for decoding (as well as the hidden internal), secure encryption of login passwords, PIN numbers, and serial codes. Inability to be cracked using the "Brute Force" (if the password is wrong does not show the classic error message intercepted by the crackers, but is decoded in the wrong way and the file will appear illegible).
