Need Help Verifying A Signature With The Python Cryptography Library

I'm trying to verify a signature using the Python Cryptography library as stated here https://cryptography.io/en/latest/hazmat/primitives/asymmetric/rsa/ This is in the context of

Solution 1:

verify raises an exception or returns None. Accordingly, this code

if verifier.verify():
    return1else:
    return0

will always return 0 even though in reality the verification check has passed. You are correct that the proper way to use verify is to wrap it in a try block and handle the InvalidSignature exception in the event of failure.
