Note: a lot of programmers talk about UI without mentionning the user even once, as if it was entirely a programming problem. I wonder what we’re leaving off the table when we do that.

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from

TURNサーバの構築

WebRTCを使ってみよう！ で紹介されている rfc5766-turn-server は既に更新が終わり、別のプロジェクトになっています。

coturn を代わりに使用します。 https://github.com/coturn/coturn/wiki/Downloads から最新バージョンをダウンロードしてビルドします。

※ダウンロードページに turnserver-*-amazon-aws-ec2-x86_64.txt というファイルあり！ EC2 ではこの内容にも注意すること
