Description:
Proton’s Hide My Email feature is great for protecting my real email address, but currently, it breaks end-to-end encryption (E2EE) because emails are decrypted at the forwarding stage before reaching my inbox.

For a truly private experience, Hide My Email should maintain full E2EE, ensuring that messages remain encrypted from sender to recipient without being decrypted by Proton servers.

Proposed Solution:

Each Hide My Email alias could have its own public-private key pair, so messages sent to it are encrypted independently.

Proton could use Proxy Re-Encryption (PRE) or a similar method to re-encrypt messages without ever exposing plaintext before delivering them to the user’s Proton Mail inbox.

Emails should remain encrypted until I decrypt them on my device, just like regular Proton Mail messages.

Why This Matters:

Maintains Proton’s core promise of end-to-end encryption.

Ensures Proton’s servers never see plaintext emails, even in forwarding.

Strengthens privacy for users who want aliases to remain fully independent and secure.

This would make Hide My Email the most secure alias service available, giving users more control over their privacy.
