- sp332 3y agoThat's if you have control of both images. With a given MD5 hash, you can't make another file with that hash.
- f38zf5vdt 3y agoStill not an argument for ever using them as reliable evidence. You have to trust whoever made the original hash to not have generated it with a duplicate, innocuous image providing a collision. These hashes are not verifiable as they appear to be parts of secret databases, so you are trusting the authority of that database not to do something like make innocuous colliding images for the sake of violating your personal freedoms.
