Instagram quietly drops end-to-end encrypted chats
Instagram quietly drops end-to-end encrypted chats
I wouldn’t try to LOL
But there is valid reasoning for it. The metadata is equally as valuable as the actual content. That’s why WhatsApp is so profitable. If more people are using it then it could be seen as worth the tradeoff.
a surprising move
Was it, though?
My understanding is that Whatsapp is “real” e2e and it’s based on signal protocol. That app is the main IM in many countries so they’ll probably won’t mess too much with it
I didn’t really expect Instagram or messenger to be really encrypted
You may want to revisit that
They could always do that, and basically anything you can read on your phone, they can access if they need.
Encryption is a math thing: generate a pair of keys: one te encde, one to decode. I broadcast the one to encode (“public key”), and the whole world is tu use it to send me encrypted messages. I keep the decoding (“private key”) only for myself.
In client to erver encryption, we exchange keys with the server through which go all the comms: it decodes my messages and re-encodes them for my contact.
In e2e, the key exchange is between contacts: the server does not have the private keys.
In Meta, the proprietary app can send your private key to the server and then they know what you wrote. You have no way to know it doesn’t do so!
Opensource audited software is the only way to make sure.
I just always assumed that WhatsApp wasn’t secure…
Even more so when they made it so your chats trained their AI, default opt in, and no global setting, has to be disabled per chat.
