[Bug 1759985] [NEW] can python-crypto and pycryptodome co-exist?

[Seth Arnold]

Public bug reported:

Hello,

The pycryptodome docs have:

> The installation procedure depends on the package you want the library in.
> PyCryptodome can be used as:
>$
> #. **a drop-in replacement for the old PyCrypto library**.
>    You install it with::
>$
>        pip install pycryptodome
> $$$
>    In this case, all modules are installed under the ``Crypto`` package.
> $$$$
>    One must avoid having both PyCrypto and PyCryptodome installed
>    at the same time, as they will interfere with each other.
>$
>    This option is therefore recommended only when you are sure that
>    the whole application is deployed in a ``virtualenv``.
>$
> #. **a library independent of the old PyCrypto**.
>    You install it with::
>$
>        pip install pycryptodomex
> $$$
>    In this case, all modules are installed under the ``Cryptodome`` package.
>    PyCrypto and PyCryptodome can coexist.
>$

Currently there's no Breaks or Conflicts lines in either package:

$ grep -e Break -e Conflict pycryptodome/bionic/pycryptodome-3.4.7/debian/* python-crypto/bionic/python-crypto-2.6.1/debian/*

python-crypto/bionic/python-crypto-2.6.1/debian/changelog:  * Drop obsolete Conflicts/Replaces with python2.3-crypto and
python-crypto/bionic/python-crypto-2.6.1/debian/changelog:    - Add Breaks python{,3}-keyring (<= 0.7.1-1) to python{,3}-crypto.

Can these two packages be installed side-by-side? Or is this something 
that matters only to 'pip' installs?

Thanks
