And if so, why exactly? It says it’s end-to-end encrypted. The metadata isn’t. But what is metadata and is it bad that it’s not? Are there any other problematic things?
I think I have a few answers for these questions, but I was wondering if anyone else has good answers/explanations/links to share where I can inform myself more.
That doesn’t explain why asymmetric encryption is insecure? In fact signal seems to be using two pairs of asymmetric keys to generate its symmetric secret, so it would also be prone to attack if asymmetric encryption was a flawed system.
