Much easier Email crypto, by fetching pubkey via HTTPS
How does it work?
As an email user, you just select the recipient(s) and can see that the email will be encrypted.
If you and your peers use email-providers offering this "web key service", it works by the first email. Otherwise encryption will start after you have exchanged some emails.
Technically your email client will automatically
- prepare for this by creating a crypto key for you and uploading it to your provider (or second best to public keyservers).
- sign all emails so others see that you are ready for crypto (unless you opt out)
- ask the mail provider of your recipients for their pubkeys.
An email-provider offering the "web key service" technically has to
- provide a pubkey for users via HTTPS
- allow each user's email client to automatically manage the pubkey that gets published by email.
A way to set up such a service is document on the Web Key Service page.
