The plugin increases security of a site in case it has no SSL certificate, useful for owners of small sites who want to secure their passwords and other posted data but don't want to buy SSL certificate for each domain and subdomain: it protects from sniffering the most important data such as passwords when they are being sent from forms of your site to the server.
When the form served by the plugin is submitted all input data are being joined into a string, then this string is being encrypted with AES algorythm by disposable key and only encrypred string will be sent.
Translations included: Ukrainian, Russian, German and Brazilian Portuguese.
