Contains a hashing method that matches the hashing method described
here: [https://pypi.org/project/oshash/](https://pypi.org/project/oshash/)

This hashing method is particularly useful when you don’t want to read
an entire file’s bytes to generate a hash, provided you trust that any
changes to the file will cause byte differences in the first and last
bytes of the file, or a change to its file size.

### CLI Utility

A command line utility is provided to generate hashes for files specified as arguments.

```
$ oshash test-resources/testdata

```
