The code above is not reliable unless one understand the underlying
JCA/JCE provider behavior exactly this way. For a certain provider, an
RSA key may be not an instance of RSAKey. I would use
key.getAlgorithm() instead.
You mean that some providers do not always adhere even to RSAPublicKey (which
extends RSAKey)?
Well, then there's a lot of broken stuff out there.
