Hash Password in CI4

1. Created a Helper Function
Created helper functions for password hashing and verification to reuse across your application.

Create a file in app/Helpers, e.g., app/Helpers/password_helper.php

password_helper.php

<?php

if (!function_exists('hash_password')) {

function hash_password($password) {

return password_hash($password, PASSWORD_BCRYPT);

}

if (!function_exists('verify_password')) {

function verify_password($input_password, $stored_hash) {

return password_verify($input_password, $stored_hash);

}

2. Hash Password During Registration

1 2	$password = $this->request->getPost('password'); $hashed_password = hash_password($password);

3. Verify Password During Login

1 2	$password = $this->request->getPost('password'); verify_password($input_password, $user->password);

If the password is verified, it will return 1, else blank. e.g. below

if(verify_password($password, $user->password)) {

// Set session or other login logic

session()->set(['username' => $user->username]);

return redirect()->to('/superadmin/dashboard')->with('success', 'Login successful!');

}else {

return redirect()->back()->with('error', 'Invalid credentials!');

}
