Yii Cookies

The package helps in working with HTTP cookies in a PSR-7 environment:

provides a handy abstraction representing a cookie
allows dealing with many cookies at once
forms and adds Set-Cookie headers to response
signs a cookie to prevent its value from being tampered with
encrypts a cookie to prevent its value from being tampered with
provides PSR-15 middleware for encrypting and signing cookie values

Requirements

PHP 7.4 - 8.5.

Installation

The package could be installed with Composer:

composer require yiisoft/cookies

General usage

Adding a cookie to response:

$cookie = (new \Yiisoft\Cookies\Cookie('cookieName', 'value'))
    ->withPath('/')
    ->withDomain('yiiframework.com')
    ->withHttpOnly(true)
    ->withSecure(true)
    ->withSameSite(\Yiisoft\Cookies\Cookie::SAME_SITE_STRICT)
    ->withMaxAge(new \DateInterval('P7D'));

$response = $cookie->addToResponse($response);

Modifying response cookies to be sent:

$cookies = \Yiisoft\Cookies\CookieCollection::fromResponse($response);
$cookies->expire('login');
$response = $cookies->setToResponse($response);

Getting request cookies:

$cookies = \Yiisoft\Cookies\CookieCollection::fromArray($request->getCookieParams());

Signing a cookie to prevent its value from being tampered with:

$cookie = new \Yiisoft\Cookies\Cookie('identity', 'identityValue');

// The secret key used to sign and validate cookies.
$key = '0my1xVkjCJnD_q1yr6lUxcAdpDlTMwiU';
$signer = new \Yiisoft\Cookies\CookieSigner($key);

// Prefixes unique hash based on the value of the cookie and a secret key.
$signedCookie = $signer->sign($cookie);

// Validates and get backs the cookie with clean value.
$cookie = $signer->validate($signedCookie);

// Before validation, check if the cookie is signed.
if ($signer->isSigned($cookie)) {
    $cookie = $signer->validate($cookie);
}

Encrypting a cookie to prevent its value from being tampered with:

$cookie = new \Yiisoft\Cookies\Cookie('identity', 'identityValue');

// The secret key used to sign and validate cookies.
$key = '0my1xVkjCJnD_q1yr6lUxcAdpDlTMwiU';
$encryptor = new \Yiisoft\Cookies\CookieEncryptor($key);

// Encrypts cookie value based on the secret key.
$encryptedCookie = $encryptor->encrypt($cookie);

// Validates, decrypts and get backs the cookie with clean value.
$cookie = $encryptor->decrypt($encryptedCookie);

// Before decryption, check if the cookie is encrypted.
if ($encryptor->isEncrypted($cookie)) {
    $cookie = $encryptor->decrypt($cookie);
}

Using a PSR-15 middleware to encrypt and sign cookie values.

/**
 * @var \Psr\Http\Message\ServerRequestInterface $request
 * @var \Psr\Http\Server\RequestHandlerInterface $handler
 * @var \Psr\Log\LoggerInterface $logger
 */

// The secret key used to sign and validate cookies.
$key = '0my1xVkjCJnD_q1yr6lUxcAdpDlTMwiU';
$signer = new \Yiisoft\Cookies\CookieSigner($key);
$encryptor = new \Yiisoft\Cookies\CookieEncryptor($key);

$cookiesSettings = [
    'identity' => \Yiisoft\Cookies\CookieMiddleware::ENCRYPT,
    'name_[1-9]' => \Yiisoft\Cookies\CookieMiddleware::SIGN,
    'prefix*' => \Yiisoft\Cookies\CookieMiddleware::SIGN,
];

$middleware = new \Yiisoft\Cookies\CookieMiddleware(
    $logger
    $encryptor,
    $signer,
    $cookiesSettings,
);

// The cookie parameter values from the request are decrypted/validated.
// The cookie values are encrypted/signed, and appended to the response.
$response = $middleware->process($request, $handler);

Create cookie with raw value that will not be encoded:

$cookie = (new \Yiisoft\Cookies\Cookie('cookieName'))
    ->withRawValue('ebaKUq90PhiHck_MR7st-E1SxhbYWiTsLo82mCTbNuAh7rgflx5LVsYfJJseyQCrODuVcJkTSYhm1WKte-l5lQ==')
