+So to get the desired output, which versions of pip are required?

+One difficulty I'm seeing is that I am quite unable to determine which version

+versions for which you have some control? Either by name, version,

+docstring or some such?

+

+# locate Crypto shows

+/usr/lib64/python3.5/site-packages/Crypto

+and

+/usr/lib64/python2.7/site-packages/Crypto

+/usr/lib64/python2.7/site-packages/Cryptodome

+which would seem to be a mix.

+In the /usr/lib/python3.5/site-packages I have Crypto within which

+__init__.py I see

+# Written in 2008 by Dwayne C. Litzenberger <<A HREF="http://lists.dlitz.net/cgi-bin/mailman/listinfo/pycrypto">dlitz at dlitz.net</A>>

+So it is possibly pycrypto original.

+Renamed this dir and my code fails, so this is where it's coming from.

+pip3.5 install pycryptodomex

+(my code still fails)

+pip3.5 install pycryptodome

+and my code runs.

+Unless I get further problems, I'm quite prepared to leave it at that.

+Seems I'm running pycryptodome (how to tell!) which is working.

+Are you recommending staying with pip2.7 (8.1.2) and

+pip3.5 (8.1.2) ?

+Again, thanks for the help Marty.
