Hi all, I have a question about adding the pkcs7 signed attributes to the PKCS7_SIGNER_INFO. I tried to add the transaction-id, messageType and senderNonce attributes using the function PKCS7_add_signed_attribute(PKCS7_SIGNER_INFO *p7si, int nid, int atrtype, void *value). I need them to implement the SCEP protocol.. I couldnt figure out the 2nd parameter ie., nid. I couldnt find the corresponding nids in objects.h file. How to define new object identifiers and their nids. If some one can help me with a small example it will be highly appreciated.
