Why is JavaScript encryption bad?

Why is JavaScript encryption bad?

You can’t lose a giant database of customer data if you don’t have a giant database of customer data sitting around. Javascript can encrypt stuff before it even leaves the browser. That’s much harder than stealing a database, and even if it works, it can only compromises the users who log in during the breach.

Is crypto browser is safe?

Many browser-based crypto are often reduced down to the security of the server that hosts the client side code along with the security of SSL. So for example, if the client that does the crypto is hosted on our server, then in theory anyone who compromises our server can alter it and add a backdoor.
