alt Hacker News> I've been building and promoting digital signatures for years.
I agree with this wholeheartedly, and yet I do get the following question a lot "What's all that nonsense at the end of your emails". Any explanation is met with eye-rolls and 1000 yard stares. Have you managed to get laypeople on-board with any kind of client-side cryptography? how?
Everything needs to be built into the application in a way that users don't notice if they don't care. A signature at the end of your emails is more cryptic than the recipient's email client showing an icon with a green checkmark or something similar. I take Chrome's rollout of tls-enforcement by default as a great example of this. All I would had to say to people was "check that the padlock next to your url bar is green."
