<p style="color: grey"> Python recipe 578083 by <a href="/recipes/users/4181365/">cathy park</a> (<a href="/recipes/tags/caching/">caching</a>, <a href="/recipes/tags/hashes/">hashes</a>). </p> <p>This module can be used to calculate file hashes, store them in a database file and retrieve them at a later date.</p> <p>It uses the files modify time stamp to know if it can use the hash stored in the db or if it has to re-calculate it. So the user will not have to worry about the hash being incorrect if the file changes in between runs.</p>
