[Python-RSA](https://stuvel.eu/rsa) is a pure-Python RSA implementation. It supports

encryption and decryption, signing and verifying signatures, and key

generation according to PKCS#1 version 1.5. It can be used as a Python

library as well as on the commandline. The code was mostly written by

Sybren A.  Stüvel.

Documentation can be found at the [Python-RSA homepage](https://stuvel.eu/rsa). For all changes, check [the changelog](https://github.com/sybrenstuvel/python-rsa/blob/master/CHANGELOG.md).

Download and install using:

    pip install rsa

or download it from the [Python Package Index](https://pypi.org/project/rsa/).

The source code is maintained at [GitHub](https://github.com/sybrenstuvel/python-rsa/) and is

## Security

Because of how Python internally stores numbers, it is not possible to make a pure-Python program secure against timing attacks. This library is no exception, so use it with care. See https://github.com/sybrenstuvel/python-rsa/issues/230 and https://securitypitfalls.wordpress.com/2018/08/03/constant-time-compare-in-python/ for more info.

For instructions on how to best report security issues, see our [Security Policy](https://github.com/sybrenstuvel/python-rsa/blob/main/SECURITY.md).

## Setup of Development Environment

```

python3 -m venv .venv

. ./.venv/bin/activate

pip install poetry

poetry install

```

## Publishing a New Release

Since this project is considered critical on the Python Package Index,

two-factor authentication is required. For uploading packages to PyPi, an API

key is required; username+password will not work.

First, generate an API token at https://pypi.org/manage/account/token/. Then,

use this token when publishing instead of your username and password.

As username, use `__token__`.

As password, use the token itself, including the `pypi-` prefix.

See https://pypi.org/help/#apitoken for help using API tokens to publish. This

is what I have in `~/.pypirc`:

```

[distutils]

index-servers =

    rsa

# Use `twine upload -r rsa` to upload with this token.

[rsa]

  repository = https://upload.pypi.org/legacy/

  username = __token__

  password = pypi-token

```

```

. ./.venv/bin/activate

poetry build

twine check dist/rsa-4.10-dev0.tar.gz dist/rsa-4.10-dev0-*.whl

twine upload -r rsa dist/rsa-4.10-dev0.tar.gz dist/rsa-4.10-dev0-*.whl

```
