[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).

## Security
|
||
|
|
|
||
|
|
Because of how Python internally stores numbers, it is very hard (if not impossible) to make a pure-Python program secure against timing attacks. This library is no exception, so use it with care. See https://securitypitfalls.wordpress.com/2018/08/03/constant-time-compare-in-python/ for more info.
