https://pycryptodome.readthedocs.io/ uses the Crypto namespace
https://pypi.org/project/pycryptodomex/ is a fork of Cryptodome that
uses the Cryptodome namespace.

Some distributions went with pycryptodomex, others with pycryptodome.

The key can contain '/' so it can't be separator.
id should not be the full url, just "<server id>#<client key>".
Tests should only be on configured url, not hardcoded zerobin instances.

Do not accept anymore pastes from other instances than the configured
instance.
