Poor Johnny still won't encrypt
Why email encryption lags behind HTTPS
- Commenters note most web traffic is HTTPS while email—often more sensitive—remains mostly unencrypted end-to-end.
- HTTPS became ubiquitous partly due to browser and search engine pressure; email has no comparable central push.
- Transport-level TLS between mail servers is now widespread, but end-to-end encryption is seen as breaking spam filtering, server-side rules, search, and especially webmail.
- Key discovery and cross-client support (S/MIME, PGP) remain fragmented and poorly standardized.
Usability, key management, and data longevity
- Personal key management across devices is widely viewed as the core unsolved problem: devices die, get stolen, or fall in lakes; users lose chat/email histories and keys.
- Some want a “super dumb, robust” multi-device key store; others suggest passkeys, hardware tokens (YubiKey-like rings/bracelets), or local password managers.
- There is tension between people who prioritize reliability and history vs. those who prioritize maximum security even at the cost of data loss.
- Losing access to S/MIME-encrypted email archives is cited as a real-world failure mode; some wish clients would store messages decrypted locally once received.
Threat models and tradeoffs
- One camp adopts a strong adversary model (states, pervasive surveillance) and accepts losing history as a feature.
- Another camp assumes weaker threats (random hackers, scams) and is willing to soften security to preserve archives and usability.
- It’s argued that if only “people with something to hide” use strong tools like Signal or PGP, they become easier surveillance targets; mainstream adoption matters.
Is encryption needed for email?
- Several see email as a “digital postcard,” mostly spam and notifications, fine without heavy crypto; for private messaging they prefer other tools.
- Others stress that people expect email to be private (password-protected accounts, sensitive content, receipts, logins), so default encryption would be safer than relying on users to choose.
Tools, providers, and ecosystems
- Mentioned tools: DeltaChat (moving away from classic email), mutt + GPG, Thunderbird, Mailvelope, Signal, WhatsApp, self-hosted bridges, password managers.
- Proton Mail draws criticism for limited interoperability and legal exposure, but others point out its public-key lookup endpoints do exist.
- An example from a small company and from government smart-card deployments shows S/MIME-by-default can work in controlled environments, albeit with search, webmail, and interop drawbacks.
