jdufresne and sybrenstuvel Fix BytesWarning in tests
Shouldn't try to coerce bytes to a string. Instead, print the repr
value (e.g. b'mybytestring').

When running tests with the Python `-b` option, fixes warnings of the
form:

.../python-rsa/tests/test_strings.py:34: BytesWarning: str() on a bytes instance
  print("\tMessage:   %s" % message)
.../python-rsa/tests/test_strings.py:37: BytesWarning: str() on a bytes instance
  print("\tEncrypted: %s" % encrypted)
.../python-rsa/tests/test_strings.py:40: BytesWarning: str() on a bytes instance
  print("\tDecrypted: %s" % decrypted)

Pure Python RSA implementation

PyPI Build Status Coverage Status Code Climate

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.

Download and install using:

pip install rsa

or download it from the Python Package Index.

Major changes in 4.0

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.
