@freemo @jump_spider Thanks for posting, I just finished reading the Discourse message and the blog post.

Blog post looks good, but I would suggest that if you are writing for a lay person, you would need more on the introduction, before you jump into the keys, and more complex details.

I would suggest a backgrounder on how crypto has been used since Antiquity, one of the most used methods for a long time was called Cesar's if my memory doesn't fail me. I love history and have a good book with stories about the different methods people developed over time to secure communications, it's fascinating.

To relate to the common user, again, you could bring in that communications on the web can (and should) be using encrypted messages, without any special effort from the user, and show some snapshots of the locks on the browser location box.

And maybe talk about instant messengers, and the different approaches they take to handle securing these communications (again, effortless to the user).

Nice job, thanks for requesting input. I hope you find my suggestions useful.
