[Duplicity-talk] pycryptopp?

[Scott Hannahs]

In installing duplicity on OS X, I decided to use python 3.7 since it is time 
to make a break with python 2.7.  I have an interesting issue.  The document 
say that pycryptopp is needed for the sap backend along with paramiko.  However 
pycryptopp itself is not python 3.7 compatible, only python 2.6 and 2.7
https://pypi.org/project/pycryptopp/

Am I misinterpreting something?  Can you only use the scp/sftp backend with 
python 2.7?
