The instructions to install pycryptodome says not to install over PyCrypto, but does not tell how to figure this out. I tried a locate on pycrypto and came up empty. I am kind of assuming that means I don't have it install.
Also I am assuming I should run pip as sudo, and should I use pip3?

I use cSHAKE in a number of my IETF standards (e.g. rfc9374). I would
like to be able to have a decent way to perform cSHAKE in a python
script, but it does not seem to exist. OpenSSL supports SHAKE but not
cSHAKE (it seems).
sooo what to do.
I have found:
https://github.com/Hemoth/cSHAKE
This is for python2., Fedora has python3.
which seems reasonable, but I am not experienced enough with this end of
things to do the building of the module to use per the instructions in
the script and of course wonder if there is something better out there.
I searched my Fedora mail folder and don't see any thread discussing cSHAKE.
Does anyone have experience/knowledge of how to get a cSHAKE function
call on Fedora in python?
https://github.com/lowRISC/opentitan/issues/6694 says cSHAKE from the above
has been merged into https://www.pycryptodome.org/.
Looking at the ChangeLog:
3.12.0 (4 December 2021): resolved GH#566: cSHAKE128/256 generated a wrong output for customization strings longer than 255 bytes.3.11.0 (8 October 2021): Added cSHAKE128 and cSHAKE256 (of SHA-3 family). Thanks to Michael Schaffner.
