Source, please? Suppose the hashes and PDF were provided over HTTPS. How would it be easy to create another document that collided with all 3 hashes?
Not trying to be facetious - just wondering.
- billyhoffman 11y agoahhh. Was mixing pre-image attacks with collision attacks in MD5. so ignore that. If its not over HTTPS, it doesn't matter there are 3 hashes. I change the doc. I generate the 3 hashes for my changed doc. I can serve those new hash values.
