CPKCS7SignedObject Class Reference

class CPKCS7SignedObject : public CSignedObject

A representation of a PKCS7 (signed data) entity This class is only used for update notifications and so does not provide full functionality. In particular, there is no means for creating a new PKCS7 object (other than from binary data),there is no means to modify it and revokation lists are not supported. The optional fields in signerinfo are not supported and are ignored.
