Hash a password with bcrypt and Python 3

hashpw.py

import bcrypt

# Need to supply the password as a byte
hashed = bcrypt.hashpw(b'somepassword', bcrypt.gensalt())
print(hashed)
#>> b'$2b$12$rbsEiL/dJymbH3453Tbhs.kEljGWNKTmp23s5iG71adGxv5jFj72S'

# To check the same password against the hashed value, use checkpw()
# The password you're testing comes first, the hashed value second.
# Getting it the other way around results in an Invalid Salt error.
# checkpw() returns True or False on the comparison.
check = bcrypt.checkpw(b'somepassword', hashed)

if check:
  print("The passwords match.")
else:
  print("Oops. The passwords do not match.")
