It would be nice if img_sha1 was displayed as a hexadecimal string (same as [[ https://en.wikipedia.org/wiki/Sha1sum | sha1sum ]]) on the information page for files uploaded in MediaWiki.
- example page on Wikimedia Commons
- API request with SHA1
- code of that page is located in includes/actions/InfoAction.php.
That way, users could verify their file is the same as the file that they uploaded.
