In case anyone else cares, I find NanaZip does a great job of showing hashes (although I mainly use it for creating/opening zip files). It is an open source fork (<a href="https://github.com/M2Team/NanaZip" title="https://github.com/M2Team/NanaZip">link</a>)
of 7-zip that is available in the Windows Store. It makes it so I can use the right click menu to quickly access a lot of different hashes.</div>

<div>If you did the calculation right, then the "USProvfiguresJan2024.pdf." you just calculated the SHA-512 hash value for is not the same file the USPTO used to calculate the SHA-512 value.</div>

<div>The problem could be that the USPTO does some processing on their end and that changes the file from the version that you uploaded so the hash strings will never match. Keep in mind however that humans have to look at these files and humans don't read
computer bits directly. We read text and images.<br>
