That's an interesting question. The tokens were replaced because of
the potential for private key extraction due to PKCS padding
(http://blog.cryptographyengineering.com/2012/06/bad-couple-of-years-for-cryptographic.html).

I'm not sure its possible to check for an updated token, unless the
token API includes a version number and the version was incremented.
Perhaps you could try the attack and see if the token leaks timing
information due to padding oracles. And I'm not sure what you would do
remotely, either.
