string generate(string $name, mixed $parameters = array(), int $referenceType = self::ABSOLUTE_PATH) Generates a URL or path for a specific route based on the given parameters. Parameters that reference placeholders in the route pattern will substitute them in the path or host. Extra params are added as query string to the URL. When the passed reference type cannot be generated for the route because it requires a different host or scheme than the current one, the method will retu

string sign(string $uri) Signs a URI. The given URI is signed by adding a _hash query string parameter which value depends on the URI and the secret. Parameters string $uri A URI to sign Return Value string The signed URI

bool check(string $uri) Checks that a URI contains the correct hash. The _hash query string parameter must be the last one (as it is generated that way by the sign() method, it should never be a problem). Parameters string $uri A signed URI Return Value bool True if the URI is signed correctly, false otherwise

Details __construct(string $secret) Constructor. Parameters string $secret A secret string sign(string $uri) Signs a URI. The given URI is signed by adding a _hash query string parameter which value depends on

class UriSafeTokenGenerator implements TokenGeneratorInterface Generates CSRF tokens. Methods __construct(int $entropy = 256) Generates URI-safe CSRF tokens. string generateToken() Generates a CSRF token. Details __construct(int $entropy = 256) Generates URI-safe CSRF tokens. Parameters int $entropy The amount of entropy collected for each token (in bits) string generateToken() Generates a CSRF
