Salting refers to adding a random token to a password before hashing it.

Salting passwords can protect you from dictionary attacks in the event of a database leak. The salt should be used when generating a hashed value of a password for storage.

import bcrypt

password = "ab9bb555-afc4-49f0-94cb-e58765e5693b"
salt     = bcrypt.gensalt()

# This is the value you should store in the database.
hashed = bcrypt.hashpw(password, salt)

# This is how you check a password once a re-enters is.
if bcrypt.checkpw(password, hashed):
  print("Password entered correctly")
