Access public key string programmaticaly

[scaytrase]

In order to build extensible communications I want to publish my public key from signing key-pair as a separate controller file.

If I try to use the following code

    public function pubkeyAction()
    {
        $key = $this->get('lexik_jwt_authentication.key_loader')->loadKey('public');
        dump($key);

        return new Response(
            stream_get_contents($key),
            200,
            ['Content-Type' => 'text/plain']
        );
    }

it shows me

Warning: stream_get_contents(): supplied resource is not a valid stream resource

Is there any convenient way to export public key without knowing the nature of underlying library that reads the key from the filesystem?

I have an option to manually fetch the key from the container parameters, but I think this is not a good choice

Sounds legit to me.
What do you think about adding an interface like e.g. KeyReaderInterface::readKey() and make the existing key loaders implement it?
Would you mind submit a PR?

Interface idea looks OK, maybe KeyDumper ? current Loader actually Reads keys already
not sure if I'm fully familiar with openssl and other libs to implement it properly

No problem, I'll do.

maybe KeyDumper ?
