I guess that after some APDU exchange you have stream message digest encrypted with smart card private key (which length is size of RSA key). Saving this to file (in binary format - which means that hex dump is converted to real byte code) gives you file which may be verified (decrypted with public key) with openssl command. Or i didn't understand your mail correctly :-)
