Auth_OpenID_Signatory

(

&$

store

)

Create a new signatory using a given store.

Definiert in Zeile 1313 der Datei Server.php.

    {
        // assert store is not None
        $this->store =& $store;
    }

createAssociation	(	$	dumb = true,
		$	assoc_type = 'HMAC-SHA1'
	)

Make a new association.

Definiert in Zeile 1372 der Datei Server.php.

    {
        $secret = Auth_OpenID_CryptUtil::getBytes(
                    Auth_OpenID_getSecretSize($assoc_type));

        $uniq = base64_encode(Auth_OpenID_CryptUtil::getBytes(4));
        $handle = sprintf('{%s}{%x}{%s}', $assoc_type, intval(time()), $uniq);

        $assoc = Auth_OpenID_Association::fromExpiresIn(
                      $this->SECRET_LIFETIME, $handle, $secret, $assoc_type);

        if ($dumb) {
            $key = $this->dumb_key;
        } else {
            $key = $this->normal_key;
        }

        $this->store->storeAssociation($key, $assoc);
        return $assoc;
    }

getAssociation	(	$	assoc_handle,
		$	dumb,
		$	check_expiration = true
	)

Given an association handle, get the association from the store, or return a ServerError or null if something goes wrong.

Definiert in Zeile 1397 der Datei Server.php.

    {
        if ($assoc_handle === null) {
            return new Auth_OpenID_ServerError(null,

        }

        if ($dumb) {
            $key = $this->dumb_key;
        } else {
            $key = $this->normal_key;
        }

        $assoc = $this->store->getAssociation($key, $assoc_handle);

        if (($assoc !== null) && ($assoc->getExpiresIn() <= 0)) {
            if ($check_expiration) {
                $this->store->removeAssociation($key, $assoc_handle);
                $assoc = null;
            }
        }

        return $assoc;
    }

invalidate	(	$	assoc_handle,
		$	dumb
	)

Invalidate a given association handle.

Definiert in Zeile 1425 der Datei Server.php.

    {
        if ($dumb) {
            $key = $this->dumb_key;
        } else {

        }
        $this->store->removeAssociation($key, $assoc_handle);
    }

sign

(

$

response

)

Given a response, sign the fields in the response's 'signed' list, and insert the signature into the response.

Definiert in Zeile 1339 der Datei Server.php.

    {
        $signed_response = $response;
        $assoc_handle = $response->request->assoc_handle;

        if ($assoc_handle) {
            // normal mode
            $assoc = $this->getAssociation($assoc_handle, false, false);
            if (!$assoc || ($assoc->getExpiresIn() <= 0)) {
                // fall back to dumb mode
                $signed_response->fields->setArg(Auth_OpenID_OPENID_NS,
                             'invalidate_handle', $assoc_handle);
                $assoc_type = ($assoc ? $assoc->assoc_type : 'HMAC-SHA1');

                if ($assoc && ($assoc->getExpiresIn() <= 0)) {
                    $this->invalidate($assoc_handle, false);
                }

                $assoc = $this->createAssociation(true, $assoc_type);
            }
        } else {
            // dumb mode.
            $assoc = $this->createAssociation(true);
        }

        $signed_response->fields = $assoc->signMessage(
                                      $signed_response->fields);
        return $signed_response;
    }

verify	(	$	assoc_handle,
		$	message
	)

Verify, using a given association handle, a signature with signed key-value pairs from an HTTP request.

Definiert in Zeile 1323 der Datei Server.php.

    {
        $assoc = $this->getAssociation($assoc_handle, true);
        if (!$assoc) {

            //             % (assoc_handle, sig))
            return false;
        }

        return $assoc->checkMessageSignature($message);
