JFYI (as apparently you did not get the joke):

Data encryption in and by client-side script code is *false* security – 
“security by obscurity”: It does _not_ increase security *at all* because 
*you serve* the used encryption algorithm to a potential attacker.

The proper solution for more security on Web sites are authentication and 
stronger encryption on the *transport* layer (TLS with big[ger] key lengths) 
instead.  Not only does this reduce the risk of successful man-in-the-middle 
(MITM) attacks, it also allows one to determine if the data has been 
tampered with.
