Description of problem: package python-crypto (resp. python3-crypto) is not available. As a result some other packages can't be installed - for example python3-impacket. Please could you build it for EPEL8? If you do not want to bother I offer hand for maintaining the EPEL8 branch.
I'd really rather not. It's dead upstream and users should really try to move over to python-cryptodomex if at all possible. See also Bug #1758310, Bug #1869809 and Bug #1902009.
the package is in rawhide, f34,f33, f32, ... do we really need to start retiring the support for it from EPEL8? I will be happy to maintain it for EPEL8 as long as you have it working in rawhide.
Anyway the change to pycryptodomex makes sense ... I will try to suggest that upstream. It is already used by the majority of the package.
