## Opis

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.

A browser encrypts the disposable key in javascript by the RSA public key
 and sends
it to the server; then the server decrypts it with the RSA private key and then 
use it to decrypt the posted data with AES.

Translations included: Ukrainian, Russian, German and Brazilian Portuguese.

I just adapted usage in WordPress the jCryption jQuery plugin, v. 3.1.0.

## Instalacja

Upload wp-jcryption.zip using the wordpress plugin installation interface and activate
the plugin. On the very first activation 1024-bit RSA key pair will be generated
and the list of forms the plugin is primarily destinated for will be saved. You 
may add other form IDs to this list on the plugin settings page: Settings – WP jCryption.

  Installation Instructions

Upload wp-jcryption.zip using the wordpress plugin installation interface
 and activate
the plugin. On the very first activation 1024-bit RSA key pair will be generated
and the list of forms the plugin is primarily destinated for will be saved. You 
may add other form IDs to this list on the plugin settings page: Settings – WP jCryption.

  Why should I use this plugin?

If you don’t use https on your site your password could be stolen through
 man-in-
the-middle attack when you are submitting log-in form because form data (including
password) are being sent as plain text. This plugin encrypts submitted data in a
way similar to https transmission.

  Does this plugin encrypts transmission of my site pages entirely?

No. The plugin encrypts only data being posted from most important forms
 (that 
contain password fields: login, reset password, user profile) and forms you specify
additionally. To secure all incoming and outgoing traffic of your site a SSL certificate
is needed.

  I have SSL certificate installed on my site already. Do I need to install the 
plugin?

No.

  Can I check whether the form data are being sent encrypted?

Yes, you can do it by means of Firefox LiveHTTPHeaders extension, Fiddler or similar
tools.

  What are system requirements for the plugin?

PHP version >= 5.3 with OpenSSL PHP extension.

  Do I need to generate RSA private and public key files with Linux commands?

No. PHP generates keys for you and save them in a database. So, this plugin is usable
on (almost) any shared hosting.

  The plugin works with login form but disables other form during it’s being submitted.

Try to enable the plugin option: Fix button id=”submit” and name=”submit”.

For a number of years I found this plugin to be quite indispensable, since until
recently I did not have access to SSL-encryption. If ever I were to set up WordPress
on a server that lacked SSL again, WP jCryption Security would be the first plugin
to install!
