I have written code to generate public and private keys. It works great at Python 3.7 but it fails in Python 3.8. I don't know how it fails in the latest version. Help me with some solutions.
Here's the Code:
from Crypto.PublicKey import RSA
def generate_keys():
modulus_length = 1024
key = RSA.generate(modulus_length)
pub_key = key.publickey()
private_key = key.exportKey()
public_key = pub_key.exportKey()
return private_key, public_key
a = generate_keys()
print(a)
Error in Python 3.8 version:
Traceback (most recent call last):

AttributeError: module 'time' has no attribute 'clock'
From the Python 3.8 doc:
The function
time.clock()
has been removed, after having been deprecated since Python 3.3: usetime.perf_counter()
ortime.process_time()
instead, depending on your requirements, to have well-defined behavior. (Contributed by Matthias Bussonnier in bpo-36895.)
