Mark ab/7061308 as merged in stage. Bug: 180401296 Merged-In: Id3d0f32fd0438f758a360d6fd633483bace49191 Change-Id: I7c45854e2a3c17ca8f58fad233ebdb32c81ed3cb
Python-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. For all changes, check the changelog.
Download and install using:
pip install rsa
or download it from the Python Package Index.

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.
Version 4.0 was the last version to support Python 2 and 3.4. Version 4.1 is compatible with Python 3.5+ only.
Version 3.4 was the last version in the 3.x range. Version 4.0 drops the following modules, as they are insecure:
rsa._version133
rsa._version200
rsa.bigfile
rsa.varblock
Those modules were marked as deprecated in version 3.4.
Furthermore, in 4.0 the I/O functions is streamlined to always work with bytes on all supported versions of Python.
Version 4.0 drops support for Python 2.6 and 3.3.
