public class AuthenticatedData
extends ASN1Object

RFC 5652 section 9.1: The AuthenticatedData carries AuthAttributes and other data which define what really is being signed.

 AuthenticatedData ::= SEQUENCE {
       version CMSVersion,
       originatorInfo [0] IMPLICIT OriginatorInfo OPTIONAL,
       recipientInfos RecipientInfos,
       macAlgorithm MessageAuthenticationCodeAlgorithm,
       digestAlgorithm [1] DigestAlgorithmIdentifier OPTIONAL,
       encapContentInfo EncapsulatedContentInfo,
       authAttrs [2] IMPLICIT AuthAttributes OPTIONAL,
       mac MessageAuthenticationCode,
       unauthAttrs [3] IMPLICIT UnauthAttributes OPTIONAL }

 AuthAttributes ::= SET SIZE (1..MAX) OF Attribute

 UnauthAttributes ::= SET SIZE (1..MAX) OF Attribute

 MessageAuthenticationCode ::= OCTET STRING

Return an AuthenticatedData object from a tagged object.

Parameters:

obj - the tagged object holding the object we want.

explicit - true if the object is meant to be explicitly tagged false otherwise.

Throws:

Parameters:

obj - the object we want converted.

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.
