Cynapse MailCryptor is a tool to create encrypted, self decrypting HTML documents out of plain or formatted text. These encrypted HTML documents could be sent as private messages via e-mail or could be uploaded to websites for restricted access to the information. Documents encrypted do not require any special software except for Microsoft Internet Explorer to be decrypted. This is achieved by embedding the encryption cipher into the HTML. Even though the cipher is embedded into the HTML document, the security is not vulnerable in any way, as it uses a 128 bit symmetric key encryption algorithm. This kind of algorithm does not store the password inside the document. The decryption process is done by the browser itself.
