Ilias, Patrick,
thanks a lot for your help ...
as a matter of fact I am getting the public key from the associated X509
certificate
(and I saw it comes out reversed form the card file), it does work now by
feeding
the RSA signature command with the reversed MD5 digest, damned little-big
endian !
Best regards,
Antonio

CryptoFlex cards. I suppose you are using the capability of the card to
generate RSA keys and then you are reading the public module. One reason
the signature verification might not be working is the little-big endian
issue. In plain english try reversing the bytes of the key you just read.
