<p>I provided a blog post with a practice file that a person could
use to practice using the hash tool.</p>

<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>

<div dir="ltr">BACKGROUND (The Old Days -- EFS Web)</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Until 2023, we always submitted
filings via EFS web. EFS web provided the BYTE
COUNT upon filing.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">This was great and important.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">If 3 years later, when filing the
figures for a continuation application, I wanted
to make 100% sure that I was re-filing the <i>exact
same pdf file </i>(instead of another version
with the same file-name),</div>
<div dir="ltr">I would check the byte count (usually
using an MS-DOS window - yeah, I am over 50 years
old) to make sure.</div>

<div dir="ltr">PATENT CENTER (I need the same
functionality that I used to have)</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">Now we live in the world of SHA-512 -
Patent Center gives SHA-512 rather than bye count.</div>
<div dir="ltr">I want to do the same for Patent
center - I want the ability to take a pdf file on
my computer (e.g. 11 months after filing a US
provisional), run it through SHA-512 and reproduce
the SAME SHA-512 string.</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">I am embarrassed to say that I TRIED
and I FAILED</div>
<div dir="ltr"><br>
</div>
<div dir="ltr">In Jan 2024, a US provisional was
filed -- the drawings file
(USProvfiguresJan2024.pdf had a SHA-512 value of
"abcdefg".</div>
