No, reason 101 is RSA_R_BAD_E_VALUE, assuming you're sure this was the return value from ERR_GET_REASON. This can only come from RSA_F_RSA_GENERATE_KEY. So either you're not giving the correct reason code or you're getting an error from a previous function. > I'm using OpenSSL 0.9.8e and WinXP/Visual Studio 2005. > The modulus and exponent values I set to the structure are read > from a smartcard. Are you sure you want RSA_public_decrypt? This is normally only used for cust signature processing. (Normally decryption requires the private key.)
