Cool, but there is not such a thing as secure mail communcation, never forget this
Yeah there is. It's old too and needs no qraphics.
Furthermore, nothing is absolute except the lack of absolute. It's all about gradients, targets means, barriers and most of it doesn't matter but that doesn't mean what you think it should mean and neither does that.
Can someone explain what the point is when the email contents are all read by the sender? Everything is already in a database somewhere.
Well, if the other person uses protonmail, your client encrypts the email content before submitting it, which means protonmail can't read it.
If they do not use protonmail, well, protonmail can. They apparently store the emails after they have been sent encrypted with a key in your account, so they can't read them afterwards.
About 99% of the world doesn't use protonmail. What good does it do if your email is stored unecryptes in the recipient's imbox over on gmail, apple mail, copilot 360, yahoo, yandex, or whatever else?
pretty much. that's why you don't use email for sensitive stuff.
I wish we replaced email with matrix.
Proton mail apparently can't read it. They actually can.
They've also proven that they'll give your information to law enforcement in a heartbeat.
I can encrypt a message with your public key, and only you can decrypt it. The db will store the encrypted version.
For example.
This is not necessarily what/why they do it, just one example of how asymmetric ciphers can be useful in an email scenario.
Just about nobody uses that. Your bank, your online store, your doctor, the state, and about everybody except Alice and Bob send you unencrypted mail.
Encrypting your email once received is like storing your postcards in a safe.
It was just an example. Maybe you have your private key locally to access your email, so that if there is a security breach it's impossible for them to release unencrypted emails?
I mean I don't know why, but there are loads of good examples of why someone would.
It seems that I can set it from the Android app, not from the web interface.
Does anybody know what the (potential) repercussions are of enabling PQC? I would hate it if I lost access to some emails this way.
edit: see this message. The feature is temporarily disabled as some users of Proton Drive for Windows (Tux is still crying..) reported issues with sync after enabling PQC. PQC only applies to new encrypted emails going forward.
Tux don't cry. 'Specially not about obvious lies.
Wonder how long before they come up with their own "secure" messaging platform.. $50 says before the end of the year.
I cant see any way to turn this on? I tried the instructions at https://proton.me/support/mail-post-quantum-protection but the option just isn't there on my screen. Checked web and linux desktop app and cant even find anything about encryption on the android app.
