Blue Tango is a way to make your messages discrete. It allows you to keep documents and messages confidential. The document can be plain, formatted (rich), or HTML. The message can be e-mail or chat session (like messenger). You create the text and scramble all or portions of it using a password of your choosing. Recipients can unscramble the encoded portions as long as they know the password. No expensive "secure" transmission is needed. You simply transmit the text as usual (with any or all of it encoded). The recipient simply receives it and unscrambles the encoded sections by entering the password that originally encrypted the text.
