It should be entirely unfeasible if its good crypto In order to deepfake it, a neural net would have to understand the crypto algo in such a way it could modify its deepfake input to collide with the original input's hash. Basically it would need to reverse the crypto to generate all frames that evaluate to a certain hash, and then find one that is mostly similar to the intended input. I don't think it will be realistic at all, if even theoretically possible.
