Hoover Institution: Hoover Library & Archives Releases Open-Access Software on GitHub

From the Hoover Institution:

The first set of tools is utilities for making and verifying indexed MD5 checksum files on a Macintosh computer. These files are essential for ensuring our files do not change either when uploading to our preservation server or as the file resides on the server over time.

We made these because our preferred checksum app does not support Macintosh, and we were unable to find another app that could produce indexed checksum files. Leveraging the Python programming software that ships with every Mac, we were able to solve this problem.

The second tool is a way to automate what audio engineers call a null test. It tells us if two different files have the same audio content by manipulating how audio signals with opposite phase cancel each other. This has a variety of uses. For example, it ensures that when we embed metadata into the header of a file, the pure-audio section remains intact.
