<p style="color: grey"> Python recipe 578081 by <a href="/recipes/users/4177096/">eysi</a> (<a href="/recipes/tags/caching/">caching</a>, <a href="/recipes/tags/hashes/">hashes</a>). Revision 4. </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>

I implemented it as an experiment, and since I'm in Europe I do not believe a software patent can apply to anything I write.</p>
