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

Method Details
-
getInstance
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:
IllegalArgumentException
- if the object held by the tagged object cannot be converted.
-
getInstance
Return an AuthenticatedData object from the given object.Accepted inputs:
- null → null
