Well, i want to put the "signingTime" attribute first.
Where can i find a complete list of available attributes, with their OID and meaning?

Thanks,
Massimo Gaddini

You will have to create a CRYPT_ATTRIBUTE structure with oid as
szOID_RSA_signingTime and set its reference as the value of rgAuthAttr.
Its a single valued attribute with CRYPT_ATTR_BLOB containing the asn
encoded UTC time (You can use CryptEncodedObject with the same Oid to obtain
the encoded data).

Depending on the attribute you want and if its a known attribute, you should
find it in the help for CryptEncodeObject or in Wincrypt.h

Thanks,
Vishal [MSFT]
