GPG doesn’t solve the problem of metadata surveillance. One of the major problems with technological solutions to privacy problems is that metadata surveillance is extremely useful to begin with, and it’s hard to make communication anonymous.
- upofadown 5y agoTrue but people with private communications don't usually need to hide their metadata. Who cares if they know you are communicating with your friends and family if they don't know you are complaining about the thin skinned government. Anonymity is an issue, but it is far from the most important issue.
- dane-pgp 5y agoFor what it's worth, implementations like Delta Chat support encrypted subject lines[0]. Also, it would be relatively simple for mail providers to act as two halves of a Cypherpunk remailer[1]. By that I mean that when alice@sender writes an email to bob@recipient, the sender server only sees "remailer@recipient" as the recipient and the recipient server only sees "remailer@sender" as the sender. That approach just requires some onion-layering of the emails with encryption, and a reserved key-pair advertised per mail server.
