Ext.util.base64

I'm curious as to why there are no utility functions for base64/AES/etc in ExtJS.

I know that we should use HTTPS to ensure encryption between client/server.

However, I want to add another layer of security above that.

Simply put, I don't trust that HTTPS is 100% infallible. Especially when things like HeartBleed and potential back-doors are intentionally written into the security protocols (think big-gov or NSA).

There are too many news reports where the DB was compromised and user data stolen. I use multiple layers of ciphers and one-way salts for sensitive data. This may be overkill, but better than being liable for millions of dollars.

So... Why do we have no utility classes for ciphers and encryption? There are plenty of singleton JavaScript libraries out there. Why not for ExtJS as well?
