I believe the script thinks that the private_key it is using is not correct. I am able to read the private_key.pem in my decrypt.py script but it errors out.

I am able to export the Private_key.pem, public_key.pem and even the secret.txt file. I am able to encrypt the text but when it comes to decrypting I get an error (See bottom of question). Try to provide an easy explanation as I am a newbie in Python.So I have created 2 files one for encryption and other for decryption. Can someone please help in parallelizing the decrypt function loop and make the program faster? Since the decrypt function is calculating large numbers the calculation is really consuming a lot of time.
