Obtaining CA signature from the CRL...

I have been trying to obtain the signature of the CA from the CRL (so
that I can verify the signature by calling
CryptVerifyCerificateSignatureEx). As far as I can tell, there doesn't
seem to be an obvious way of doing it.

The CRL_INFO structure only contains the signing algorithm, but not
the signature itself. Calling CryptoDecodeObject with
X509_CERT_CRL_TO_BE_SIGNED with the raw CRL bytes returns success, but
what's the type of structure that's returned?

Can someone shed light on the matter?

Thanks,
Atul
