After this announcement, I am planning to reject meetings organised in zoom. But the problem is that it’s really good. So, is there any privacy friendly and viable alternatives to zoom? It does not have to be open source because I nearly tried all alternatives. Your experiences?
Proton Mail uses PGP which depends on which cipher both recipient and sender, sharing PGP keys are also problematic. PGP doesn't encrypt subject line but Tutanota does. Tutanota uses AES-128 and RSA-2048 for their encryption and uses AES-128 for external encrypted email which Tutanota and Proton Mail also supports.
