I want my login password to be secured. So I came up to use the PHP's crypt() function to hash the password before inserting it to database. But Im having trouble when comparing the user input password from the converted hash password. Here's my code:
<?php
$password = 'hello_password';
# A higher "cost" is more secure
$cost = 10;
# Create a random salt
$salt = strtr(base64_encode(mcrypt_create_iv(16, MCRYPT_DEV_URANDOM)), '+', '.');
# Blowfish algorithm.
$salt = sprintf("$2a$%02d$", $cost) . $salt;
$salted_password = $password . $salt; // apply salt to password
# hash the password
$hash_password = hash('sha256', $salted_password);
$userInput = 'hello_password'; // suppose this is the user input password
if (hash('sha256',$userInput) == $password) {
echo "Password Verified.";
}
else {
echo "Incorrect Password";
}
?>
But it always displays Incorrect Password although my password is correct. I don't want to use "hash_equals" function as it is not supported with my current PHP version. Can someone help me with this ? Thanks
