Ask HN: What does end-to-end encryption mean?
Mobile, apologies for formatting.
I was reading Zoom's security whitepaper on their website and it says it can "encrypt presentation content at the application layer". Now I have a reasonable understanding of E2E encryption, but if the text or content has to be presented to the user by the OS, can the OS read the content of whatever the user is seeing since it has to render the graphics?
For example, can Google read my Signal messages via the fact Android has to render the text?
