When using this python script the switch will not accept the calculated hash

I've tried to use the salt that the switch has stored as a constant and calculated the hash. The has value calculated is the same as the hash in cisco running config.

                    for _ in range(14):
                        salt_chars.append(random.choice(cisco_b64chars))
                    salt = "".join(salt_chars)
                    salt = "pPsCfoFx0krK.E"  # <------------

It seems that the salt is not a random value for IOS-XE 17.03.04
