PKCS7: what can be the content type (part of Content info ) other than simple data in Signed data

[Konark]

Hello Steve,   Once again Thanks for your last solution ( Digest info ).   I have small doubt about ...     what can be the content type (part of Content info ) other than simple data in Signed data.     Structure description ................     SignedData ::= SEQUENCE {   version Version,     digestAlgorithms DigestAlgorithmIdentifiers,   contentInfo ContentInfo,   certificates       [0] IMPLICIT ExtendedCertificatesAndCertificates        OPTIONAL,   crls     [1] IMPLICIT CertificateRevocationLists OPTIONAL, signerInfos SignerInfos }   ContentInfo ::= SEQUENCE {   contentType ContentType,   content     [0] EXPLICIT ANY DEFINED BY contentType OPTIONAL } ->It seems to be content type can only be Simple data ( after looking in to the code ) -> Is it possible to put content type other than simple data like enveloped data when authenticated attributes are present . -> I also found that it is checking for other type ( always Octet string ) when simple data ( data type ) is not present    1. can i assume if simple data is not the type of content info it should go into other type ?    2. if simple data is not the type of content info i need to encode and save the encoded content . is it so ?     Regards, konark
