A lot of the Python-RSA functionality is also available as commandline scripts. On Linux and other unix-like systems they are executable Python scripts, on Windows they are .exe files.

All scripts accept a --help parameter that give you instructions on how to use them. Here is a short overview:

.. index:: CLI interface

.. index:: pyrsa-keygen, pyrsa-encrypt, pyrsa-decrypt, pyrsa-sign

.. index:: pyrsa-verify, pyrsa-priv2pub, pyrsa-encrypt-bigfile

.. index:: pyrsa-decrypt-bigfile, pyrsa-decrypt-bigfile
