Description of problem:

totpcgi currently has a runtime dependency on python3-crypto, which I maintain in Fedora. Upstream of this package (https://www.pycrypto.org/) has long since stopped maintaining it and I would like to drop it from Fedora.

Upstream of totpcgi has already switched to python-pycryptodome (see requirements.txt) but this cannot currently be packaged in Fedora because it would conflict with python-crypto due to it using the same namespace. However, python-pycryptodomex, which uses the "Cryptodome" rather than the "Crypto" namespace is available in Fedora and could be used. To use pycryptodomex, all that should be necessary is to change (in totpcgi/utils.py):

from Crypto.Cipher import AES
to:
from Cryptodome.Cipher import AES

and change the dependency from python3-crypto to python3-pycryptodomex.

Please consider applying such a change in Fedora so that python-crypto gets nearer to being able to be retired.
