How to get my password more securely

I am new with vaadiin and I developing a login form. I want to know how can I get my password in a more secure way. I mean with a hashcode or something like this.

Because of the multitude of different solutions to password security, we’ve decided that the Vaadin text components will not do any hashing (or encryption etc.). It is up to the developer to get the String from the field, and do whatever operation on it directly afterwards. We certainly reccomend you use strong security on you passwords, with the more advanced hashes (with salts) being a good alternative.

If you are worried about sending the password in plaintext from the browser to server, that’s an issue not unique to Vaadin by any means; all web apps do this. We strongly reccomend deploying your app on a SSL-enabled server for this reason.
