It's not as vulnerable but it still is.

Interestingly, Android is the only operating system that fully immunizes VPN apps from the attack because it doesn't implement option 121. For all other OSes, there are no complete fixes. When apps run on Linux there’s a setting that minimizes the effects, but even then TunnelVision can be used to exploit a side channel that can be used to de-anonymize destination traffic and perform targeted denial-of-service attacks.

Because good journalism isn't free and the expectation that it is leads to societal downfall ;)

Yes, lemmy is a monolith of opinions.

You really have less than zero idea of what you're talking about, this is actually hilarious.

I'll be talking about digital signatures which is the basis for such things. I assume basic understanding of asymmetric cryptography and hashing.

Basically, you hash the content you want to verify with a secure hashing function and encrypt the value with your private key. You can now append this encrypted value to the content or just release it alongside it.

To now verify this content they can use your public key to decrypt your signature and get the original hash value, and compare it to their own. To get that, they just need to hash the content themselves with the same function.

So by signing their videos with the white house private key and publishing their public key somewhere, you can verify the video's authenticity like that.

For a proper understanding check out DSA :)

Adam Ragusea has great videos on mashed potatoes, even talking about exactly your point:

.. could.

Or he (and anyone else) could go and do one of 20000 other potentially way more interesting things with their life.

Imagine that?

"They"....

The EU is a collection of people of various political leanings, parties and affiliations. You cannot, in this context, throw them together under one word.

Yeah, authoritarianism and nationalism are very fragile when looking behind their mask.
