Processing SMIME messages by a receiving agent

Hi

This is the signed message part:

--boundary
Content-Type: application/x-pkcs7-signature; name="smime.p7s"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="smime.p7s"
Content-Description: S/MIME Cryptographic Signature

--boundary--

I am processing this message as follows:
1) Decode the base64 encoded signed data
2) BER decode the signeddata value
3) Repeat this process recursively till I get all the elements of the
signed data structure completely decode

I want to know whether i am in the right direction. Thanks

Regards
