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.
Jitsi is an alternative that works fairly well.
Jitsi would be my choice.
Subject lines and recipient/sender email addresses are encrypted but not end-to-end encrypted for Proton Mail.
Tutanota first use the user password to generate an AES key using BCrypt, that AES key is then used to encrypt the private key. The encrypted private key and hashed AES key is then sent to the server, hence the server does not store nor know the private key and the hashed AES key is used to authenticate the user. It uses SHA256 for hashing, it’s safe because the hashing algorithm is one way only and not reversible, meaning you can’t convert the hash to the password but only the other way around the password can generate the hash, so even the server is compromised it doesn’t gain access to your password.
