BCrypt Verify a Password (Check if Password is Correct)

See more Encryption Examples

A system that uses BCrypt for storing passwords would not store the actual password, but would instead store the bcrypt hash of the password. When a user presents the password, such as for login, call BCryptVerify to verify the password against the stored bcrypt hash.

Note: This example requires Chilkat v9.5.0.65 or greater.

CkPython

import chilkat

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

crypt = chilkat.CkCrypt2()

storedHash = "$2a$10$H5kIVktMGzAPKGKNAe9DVu0iwEqfhv/o4MMJ/Dzw/MPy1leOE9NOK"
password = "mySecretPassword"

passwordValid = crypt.BCryptVerify(password,storedHash)
if (passwordValid == True):
    print(password + " is valid.")
else:
    print(password + " is NOT valid.")

password = "notAValidPassword"
passwordValid = crypt.BCryptVerify(password,storedHash)
if (passwordValid == True):
    print(password + " is valid.")
else:
    print(password + " is NOT valid.")

# Output should be:

# 	mySecretPassword is valid.
# 	notAValidPassword is NOT valid.
