Hi guys.

I'm getting an ImportError for 'SHA256' when using Crypto.Hash in crypto.py

crypto.py includes:

from Crypto.Hash import (
    SHA256 as _sha256,
    SHA512 as _sha512,
)
def SHA256(x: bytes) -> bytes:
    return _sha256.new(x).digest()

I'm using Python 3.11.2 on Raspberry PI 5.

According to my web searches, this is caused by pycryptodome...

I uninstalled and then reinstalled (using pip3) pycryptodome but that didn't help...

Any ideas?

One must avoid having both PyCrypto and PyCryptodome installed at the same time, as they will interfere with each other.

Uninstall both, then reinstall PyCryptodome.
