jCryption is a javascript HTML-Form encryption plugin, which encrypts the POST/GET-Data that will be sent when you submit a form. It uses the Multiple-precision and Barrett modular reduction libraries for the calculations and jQuery for the rest. jCryption is completly free and dual licensed under the MIT and GPL licenses like jQuery.

Normally if you submit a form and you don’t use SSL, your data will be sent in plain text. But SSL is neither supported by every webhost nor it’s easy to install/apply sometimes. So I created this plug-in in order that you are able to encrypt your data fast and simple. jCryption uses the public-key algorithm of RSA for the encryption.

jCryption at it’s current state is no replacement for SSL, because there is no authentication, but the main goal of jCryption should be a very easy and fast to install plugin which offers a base level of security.
