Recipient-specific encryption keys
Instead of setting an encryption key for each email I send to non-ProtonMail users, I would like to set an encryption key for each recipient.
This allows me, for example, to agree upon separate encryption keys for John and Dave, so that they can decrypt emails with their own unique password. Then when I send an email to both of them, their individual copy of the email is encrypted separately with the key I have assigned to them.
This also relieves me of the burden of constantly creating keys and hints for people I regularly correspond with.

It would be extremely useful if encryption settings can be set 'per recipient' for non-protonmail recipients. options such as;
1: always use encryption for this recipient?
2: ask each time whether to use encryption for this recipient?
3: use a differant agreed encrytion key for each recipient
additionally, would it be possible to provide an option to use a differant 'From: address, ie with (ENC) suffix to the name which will send using the preset encryption settings enabled, or without the (ENC) to send unencrypted, or something similar as this would provide an easy way to apply, or not, the preset encryption settings from clients such as Outlook?
Yes yes... Encryption portal for recipients of Proton encrypted mail
A portal for none ProtonMail customers IS Essential:
- with a portal a recipient is able to create their own account to view encrypted emails from a ProtonMail sender.
- a ProtonMail mail sender does not have to regenerated new keys.
- plus the recipient doesn't have to administered the passwords.
- no need to manually administered keys or passwords for none ProtonMail recipient's
- future proof ProtonMail, none customers are able to administered all ProtonMail senders within one portal, i.e I have to other business ProtonMail plus users, and we have the same clients on none ProtonMail system..... their getting upset not seeing the other 2 ProtonMail senders including email every email has virtually a new key!!
Currently ProtonMail plus is not enterprise business ready, due to its limitations.

Another addition to this that I have seen used elsewhere is to allow an outside recipient to set their own secret password of their choosing to be used going forward when sending to them.
Ideally I would like to have the one they set then be used by default but still have the option to override that and use the current mechanism.
