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.

Rust

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

let crypt = chilkat::Crypt2::new();

let stored_hash = "$2a$10$H5kIVktMGzAPKGKNAe9DVu0iwEqfhv/o4MMJ/Dzw/MPy1leOE9NOK".to_string();
let mut password = "mySecretPassword".to_string();

if crypt.b_crypt_verify(&password, &stored_hash).is_ok() {
    println!("{} is valid.", password);
} else {
    println!("{} is NOT valid.", password);
}

password = "notAValidPassword".to_string();
if crypt.b_crypt_verify(&password, &stored_hash).is_ok() {
    println!("{} is valid.", password);
} else {
    println!("{} is NOT valid.", password);
}

// Output should be:

// 	mySecretPassword is valid.
// 	notAValidPassword is NOT valid.
