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.
