How to Hash and Verify Password With Php_hash Method

1. Hash Passwords Using the Default Algorithm With PASSWORD_DEFAULT Constant in PHP
2. Hash Passwords Using an Explicit Algorithm Using PASSWORD_BCRYPT Constant in PHP
3. Hash Passwords Using the Explicit Algorithm With PASSWORD_BCRYPT Constant and Option Parameter in PHP

We will look at how to hash a password in PHP using the default PASSWORD_DEFAULT Constant that uses the default algorithm.

We will also look at how to hash a password in PHP using the PASSWORD_BCRYPT Constant that specifies the explicit algorithm as bcrypt and using PASSWORD_BCRYPT Constant and the option parameter that allows one to specify the algorithm count and salt.

Hash Passwords Using the Default Algorithm With PASSWORD_DEFAULT Constant in PHP

We will create a hashed password using the default algorithm by specifying PASSWORD_DEFAULT in the password_hash method.

<?php
$password = Crazy556;
$encrypted_password = password_hash($password, PASSWORD_DEFAULT);
echo $encrypted_password;
?>

Output:

$2y$10$bPtyWBeqYSa3HilGaTLB1uOV6jPt0fbZwxmzexXWQ3RKb8BeL3VOW

Hash Passwords Using an Explicit Algorithm Using PASSWORD_BCRYPT Constant in PHP

We will create a hashed password using the bcrypt algorithm by specifying PASSWORD_BCRYPT in the password_hash method.

<?php
$password = Crazy556;
$encrypted_password = password_hash($password, PASSWORD_BCRYPT);
echo $encrypted_password;
?>

Output:

$2y$10$bPtyWBeqYSa3HilGaTLB1uOV6jPt0fbZwxmzexXWQ3RKb8BeL3VOW

Hash Passwords Using the Explicit Algorithm With PASSWORD_BCRYPT Constant and Option Parameter in PHP

We will create a hashed password using the bcrypt algorithm by specifying the PASSWORD_BCRYPT constant in the password_hash method and specifying the salt and cost strings in the options parameter.

<?php

$password = Crazy556;
$options = [
    'salt' => 'Kevin',
    'cost' => 12,
];
$encrypted_password = password_hash($password, PASSWORD_BCRYPT);
echo $encrypted_password;
?>

Output:
