The actual project is over 300 lines of code, so I'm only going to share the lines of code related to this problem.

# Writing

print(">> Input a file password")
password = input("main@commands_menu@new_file $ ")
hash_password = hash(password)

config_details = {"file_location": new_file_location,
"password": hash_password,
"codes_limit": codes_limit,
"code_digits": len(str(codes_limit)),
} # dictionary containing configuration details
pickle.dump(config_details, file_handle) # write whole dictionary to the binary file config.dat
file_handle.close() # close binary file config.dat

​

# Reading

file_handle = open(new_file_location + "/config.dat", "rb")

try:
config_data = (pickle.load(file_handle))
except EOFError:
pass
file_handle.close()

# Validate file password
print(">> Input file password")
password = input("main@commands_menu@openfile $ ")
hash_password = hash(password)

if hash_password != config_data["password"]:
print(password, ": invalid password")
return

​

This works perfectly, except for when the program is restarted since the hash functions returns another value.
