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
| Command | Usage | Core function |
|---|---|---|
| pyrsa-keygen | Generates a new RSA key pair in PEM or DER format | :py:func:`rsa.newkeys` |
| pyrsa-encrypt | Encrypts a file. The file must be shorter than the key length in order to be encrypted. | :py:func:`rsa.encrypt` |
| pyrsa-decrypt | Decrypts a file. | :py:func:`rsa.decrypt` |
| pyrsa-sign | Signs a file, outputs the signature. | :py:func:`rsa.sign` |
| pyrsa-verify | Verifies a signature. The result is written to the console as well as returned in the exit status code. | :py:func:`rsa.verify` |
| pyrsa-priv2pub | Reads a private key and outputs the corresponding public key. | - |
| pyrsa-encrypt-bigfile | Encrypts a file to an encrypted VARBLOCK file. The file can be larger than the key length, but the output file is only compatible with Python-RSA. | Deprecated in Python-RSA 3.4 and removed from version 4.0. |
| pyrsa-decrypt-bigfile | Decrypts an encrypted VARBLOCK file. | Deprecated in Python-RSA 3.4 and removed from version 4.0. |
