CMS_verify_receipt() verifies a CMS signed receipt. rcms is the signed receipt to verify. ocms is the
       original SignedData structure containing the receipt request. certs is a set of certificates in which to
       search for the signing certificate. store is a trusted certificate store (used for chain verification).

       flags is an optional set of flags, which can be used to modify the verify operation.

       CMS_verify_receipt - verify a CMS signed receipt

       This functions behaves in a similar way to CMS_verify() except the flag values CMS_DETACHED, CMS_BINARY,
       CMS_TEXT and CMS_STREAM are not supported since they do not make sense in the context of signed receipts.

CMS_verify_receipt() returns 1 for a successful verification and zero if an error occurred.

       The error can be obtained from ERR_get_error(3)

ERR_get_error(3), CMS_sign_receipt(3), CMS_verify(3),
