It encrypts your files and text (with up to 6,144-bit) and puts its contents into an extra file to be attached to an e-mail. The recipient thereof does not need to have ShyFile installed to be able to decode since any regular Internet browser is able to take care of it, i.e. opening it and prompting the user to enter a matching key phrase. You can also build a Web page that can be viewed only by the people you choose, by encrypting the text with ShyFile before uploading the page to a server. ShyFile also encrypts single or multiple binary files as well as whole folders with all its sub folders in a single run, which require a free demo version of ShyFile to decode though. It also features a secure chat (no need to enroll or become a member to anything nor to pick a chat room.) A File Shredder is included to thoroughly delete files on your hard drive in a way no undelete tool could ever restore them again. Its user friendly interface is very intuitive - no need to study the manual. Symmetric keys are used as opposed to Public and Private Keys. Any file can be used as a key. ShyFile exclusively makes use of its own independently developed powerful algorithm, offering a symmetric depth of encryption of up to 6,144-bit, which means it will take a potential hacker not knowing your password 2 to the power of 6,144 possibilities (that equals a figure with 1,850 digits) to crack it. Ten thousand years won't be enough time to cycle through all these possibilities. ShyFile works independently from all your Web-based e-mail accounts and desktop e-mail applications. This application can be controlled by simple command-lines, as in batch files or from within other programs.
