The high level S/MIME routines have only been tested where the inner content is of type 'data'. Their behaviour for other types is undefined and it is quite likely they wont work. The ASN1 PKCS7 structure should correctly encode other types: its just that they will largely need to be processed manually. The syntax of the inner content is one area where S/MIME v2 and S/MIME v3 differ. The V2 syntax is to include the ASN1 structure inside the PKCS#7 structure the V3 syntax encodes the data inside an OCTET STRING in the CMS structure. V3 is the more sensible thing to do because it avoids possible ASN1 reencoding problems. Doesn't help with OpenSSL though because it only supports V2. Steve. -- Dr Stephen N. Henson.
