You need to install the Cryptodome library. You can do so through sudo apt install python3-pycryptodome, pip install pycryptodome or pip3 install pycryptodomex. I've updated the README accordingly. Thanks!

shreyas-badiger commented 4 years ago

Thanks! The command is actually: pip3 install pycryptodomex

gannimo commented 4 years ago

This depends on your local system. If you have both legacy python and python3 installed then pip installs for legacy, otherwise pip installs for python3. I'll make a note :)

I think @hard-fault is referring not just to python3, but also to the x version of PyCryptodome.

pip install pycrotodomex works like a charm for me pip install pycrotodome gives the ModuleNotFoundError

gannimo commented 4 years ago

OK, I'll adjust. There are too many sub libraries and the different pip commands refer to different subsets of the library. Debian/Ubuntu conveniently installs both. Thanks!

Note that in a Python 3 virtual environment, you also need to install pycryptodomex instead of pycryptodome:

A spelling mistake, it's pycryptodomex.

Updated the comment to give options. Note that the README itself has much changed over time and this thread is likely no longer valid at all for this implementation.
