jCryption, is simply Javascript Encryption. “j” stands for jQuery as core framework. And as always, everybody likes 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.

Author’s site had a good documentation on usage.
