The other parts of the certificate are shown correctly. Used openssl version
is 1.0.1g. Not sure if this is our mistake or not supported by openssl. But
it works with certificates created with standard RSA keys.
Eventually we want to use libeay32.dll directly. We already did this
successfully in the past but found now X509_get_pubkey() returning NULL
using such certificates. - Maybe there exists an alternative way to read out
the public key to get a pointer to an EVP_PKEY structure?
