Show HN: Weekend project encrypted messages

Wrote this for fun. You can send message that are encrypted and message that self destruct. It uses javascript and does all the encryption in the client browser.

Anything saved on my server is encrypted bytes. Even with access to my server I cannot read what people are writing.

It seemed like a good idea, I have one ad on the page where you pickup the message. Not sure of a path to make money.

Any thoughts on anything, from UI to just in general is the idea ok.

Thanks
