ShyFile - File and Email Security

ShyFile generates self-decrypting files carrying your highly secured text (up to 6,144 bits) to be attached to an email or to be published as a webpage. Simple but yet poweful 1on1 symmetric key-entries are made use of for the email security and the encryption of HTML-pages, single binary files as well as whole folders. Any file can be used as a key. A File Shredder is included to thoroughly erase files from your hard drive.
