How can we improve ProtonMail?

Allow PGP encrypted mails to non protonmail contacts

If I want to send an encrypted mail to a non protonmail E-Mail address I can't do that right now (I mean besides that link thing)

Please add in the contacts section a way to upload the public key of a non protonmail user. That way we would be capable to send and receive PGP (GnuPG) encyrpted mails from others.

    I'm a new user and was wondering that this feature is missing. It needs to be a core feature.

    Support for sending encrypted emails by an encrypted email provider has been "Planned" for over 2 years already. In my opinion, protonmail isn't complete until it has this feature.

    Let me bump this, and shamelessly link to an excellent way to spread the usage of end-to-end encryption: autocrypt. When you start implementing this, please include autocrypt headers to outgoing emails, and import keys from incoming mails with such headers.

    even if you can't allow auto-discovery of keys (via public keyservers or rfc 7929), if we could import keys manually and just have you auto encrypt/decrypt/sign/verify that would be great.

    It would be perfect addon for proton mail to send encrypted mail tot non proton mail users. please make it work !

    Any updates on this feature? It's very necessary, please be more open about time frames, even if you miss them.

    This would be an important feature for me. While I do recommend ProtonMail to my friends (and everyone else) they are often hesitant to leave their current email provider. Convincing them to use PGP would probably be easier to do. This would allow me and my friends to communicate securely without them having to switch to PM or me using the symmetric encryption feature (and having to get the password to them somehow).

    Receiving PGP encrypted emails is already possible by exporting your public key and letting other people send encrypted emails using your PGP public key. This needs to be done with armored ASCII, and the encrypted contents need to be sent inline as part of the email's body.

    Under Linux, one would import the public key and execute: "echo 'The message to be sent' | gpg2 --encrypt --armor --recipient "" --always-trust"

    That will give you an output like:

    -----BEGIN PGP MESSAGE-----
    Version: GnuPG v2

    -----END PGP MESSAGE-----

    This is the encrypted content one would send from a non-ProtonMail address to a ProtonMaill address inline as the message body.

    Any updates for this feature ? You may gain a lot of new users implementing it.

    It seems like we are waiting forever for this and to me it's the single most important thing we need. It's marked as planned but what does that mean? Planning to me means there's a timetable. This appears to be more like a dream. Meanwhile Protonmail expends resources on building a VPN. I've been checking out the beta and it's pretty good. I suppose I'll subscribe - but mostly to support them. The fact is that a lot of other people are offering VPNs that are effectively just as good (and some better) - so why is that so critical whereas encrypted communications with non-protonmail users is only an also ran.

    I would also be nice if Protonmail could search public key servers for the appropriate key.

    This is a key feature for me. Without it, I cannot use protonmail as my primary email service provider. Currently I only use it to email other protonmail users. I would love to use protonmail more, and become a paid member. Without this feature, I cannot. I allready use PGP encryption in a lot of my email correspondence, and all that pre-existing work is null if I start using Protonmail. It would also force all my other contacts to switch to Protonmail.
    While I can see why that would be economically benificial to Protonmail, it is another reason for me to not use this service. Companies that make this kind of economically motivated choices are too easy to pressure. Money is a security flaw, and should not have too big control on security decision-making.

    I couldn't import my public key into Perfect Privacy VPN configuration panel to receive encrypted emails. They told me the followin:

    I checked the key, there are various issues:

    1) it contained some extra End-of-Lines, making it unreadable (I fixed

    2) The key seems to contain no email address. Try importing this with
    your enigmail/gpg/pgo application and you will see it is only saying

    Is it related to this topic? Will that be fixed with this topic?

    Rather than relying on public PGP servers, it would be better to (at least additionally) support RFC 7929, which is a more secure way of finding a user's public key (since people can upload spoofed data to public key servers).

    ProtonMail should also publish its users' public keys in the DNS so other services can find them.
