Running the code in the Generating keys documentation and enabling BytesWarnings with -bb results in a BytesWarning: import rsa Version 4.0 drops support for Python 2.6 and 3.3. Those modules were marked as deprecated in version 3.4.įurthermore, in 4.0 the I/O functions is streamlined to always work with bytes on all supported versions of Python.
