Anyone can digitally sign anything (maybe not easily or for free). The Whitehouse can verify or not verify whatever they choose but if you, as a journalist let’s say, want to give credence to video you distribute you’ll want to digitally sign it. If a video switches hands several times without being signed it might as well have been cooked up by the last person that touched it.
That’s fine?
Signatures aren’t meant to prove authenticity. They’re proving the source which you can use to weigh the authenticity.
I think the confusion comes from the fact that cryptographic signatures are mostly used in situations where proving the source is equivalent to proving authenticity. Proving a text message is from me proves the authenticity as there’s no such thing as doctoring my own text message. There’s more nuance when you’re using signatures to prove a source which may or may not be providing trustworthy data. But there is value in at least knowing who provided the data.
