Unless I am missing something, this didn't really teach me anything? It's more of a magical emoji black box.

On a sidenote, Codemoji broke my back button (:() and seems way over-animated for a simple three box form.

In the onboarding, you can see that the idea is to teach about the basics of ciphers. ie "early ciphers shifted the letters of the alphabet". So this is for lay users who haven't been exposed to the basics.

I think that sentence was the only clue to how it "kinda" works, and it is gone quite quickly.

Back button broke for me too in Chrome OSX. Takes you to a 404 page. https://learning.mozilla.org/codemoji/#/404

Be nice if they could incorporate this into a custom keyboard for iOS/Android etc. so that people could send 'coded' messages in situ, rather than having to resort to the website to encode/decode the text.

Nice way to introduce cipher techniques to younger people though.

You should incorporate other cipher's with emojis as well, give the users more options. That could be fun

"Ciphers are math at work" and then gives a substitution cipher as an example. This topic is challenging enough to explain without trying to explain the f(x) -> y concept without a real need for it, but pretty picture right? I know I am taking this too seriously.

whats with everything being dumbed down so hard like im being talked to like an 8 year old

Because you're just not the target, and that's fine.

According to https://blog.mozilla.org/blog/2016/06/28/meet-codemoji-mozil... this is "a fun, educational tool that introduces everyday Internet users to ciphers — the basic building blocks of encryption — using emoji"

The website was posted here to show your 8 year olds.

Although I think it would be just as effective to just tell your kids "You scramble your messages with a key and only a person with the key can unscramble your messages."

And then proceed to explain to them the conjugate DH exchange, the number field seive algorithm, and common block ciphers.

Baffling that an organization that regularly pioneers new web standards makes my back button useless upon entering the website

"Not all the pieces working together perfectly" is something that just seems to happen whenever there are large organisations... I remember a few years ago when Microsoft Azure's web interface was completely broken in the latest version of Internet Explorer at the time.

read it as Cod-emoji... Fishing for the best way to express yourself.

Substitution Ciphers, still not dead since Caesar.

But the website looks cool at least.

Substitution is still a pretty big part of modern ciphers?

this website is buggy.
