Both the sender and receiver need to share a secret or key to encrypt and decrypt. All of the major email services already support encryption (S/MIME), including Outlook, GMail, iOS Mail, Proton, etc. PGP encrypted email has been available for a long time. The problem is sharing the decryption key with the recipient, which makes encrypted email impractical except for communicating with specific individuals.
- MichaelZuo 3y agoI understand that the key has to be known ahead of time, but all the popular clients just don't support it correctly. For example Mail on iOS makes it very cumbersome.
- gregjor 3y agoPeople rarely use encryption for email so it's not a top-level feature. If you want to communicate securely with someone use Signal or WhatsApp -- email is the wrong medium. You could send encrypted paper mail too, but that would be equally cumbersome. Choose a medium and tools that already support encryption. It's a bad fit for email, and so got relegated to the obscure settings because almost no one will use it.
- MichaelZuo 3y agoYes I agree the popular email clients are as you say, hence why I made the post...
