[pycrypto] pycryptodome

[Dave Pawson]

Additional information.

 pip install pycryptodomex
Requirement already satisfied: pycryptodomex in
/usr/lib64/python2.7/site-packages


Yet...

 File "/usr/lib64/python3.5/site-packages/Crypto/Cipher/blockalgo.py",
line 141, in __init__
    self._cipher = factory.new(key, *args, **kwargs)
ValueError: IV must be 16 bytes long

So (since I'm using python3) it's picking up the Crypto library from python 3.5
and pip is installing it in python 2.7

(aside. Yum no longer used in Fedora, just replace with dnf)

python3 -m Cryptodome.Selftest
/usr/bin/python3: Error while finding spec for 'Cryptodome.Selftest'
(ImportError: No module named 'Cryptodome')

regards Dave
