- All Implemented Interfaces:
- org.bouncycastle.asn1.ASN1Encodable, org.bouncycastle.util.Encodable
- public class AuthenticatedData
- extends org.bouncycastle.asn1.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

getInstance
public static AuthenticatedData getInstance(org.bouncycastle.asn1.ASN1TaggedObject obj,
boolean explicit)
- 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.- Returns:
- a reference that can be assigned to AuthenticatedData (may be null)
- Throws:
java.lang.IllegalArgumentException
- if the object held by the
tagged object cannot be converted.
getInstance
public static AuthenticatedData getInstance(java.lang.Object obj)
- Return an AuthenticatedData object from the given object.
Accepted inputs:
null → null

- a reference that can be assigned to AuthenticatedData (may be null)
- Throws:
