Usage

.. pip-command-usage:: hash


Description
***********

.. pip-command-description:: hash


Overview
++++++++
``pip hash`` is a convenient way to get a hash digest for use with
:ref:`hash-checking mode`, especially for packages with multiple archives. The
error message from ``pip install --require-hashes ...`` will give you one
hash, but, if there are multiple archives (like source and binary ones), you
will need to manually download and compute a hash for the others. Otherwise, a
spurious hash mismatch could occur when :ref:`pip install` is passed a
different set of options, like :ref:`--no-binary <install_--no-binary>`.


Options
*******

.. pip-command-options:: hash


Example
********

Compute the hash of a downloaded archive::

    $ pip download SomePackage
        Collecting SomePackage
          Downloading SomePackage-2.2.tar.gz
          Saved ./pip_downloads/SomePackage-2.2.tar.gz
        Successfully downloaded SomePackage
    $ pip hash ./pip_downloads/SomePackage-2.2.tar.gz
        ./pip_downloads/SomePackage-2.2.tar.gz:
        --hash=sha256:93e62e05c7ad3da1a233def6731e8285156701e3419a5fe279017c429ec67ce0
