Latacora - Stop Using Encrypted Email

Key point: this isn’t (just) about PGP or SMTP, it’s email as a whole system:

Even after we replace PGP, encrypted email will remain unsafe. Here’s why:

  • If messages can be sent in plaintext, they will be sent in plaintext.
  • Metadata is as important as content, and email leaks it.
  • Every archived message will eventually leak.
  • Every long term secret will eventually leak.
