Class SignedData

  • All Implemented Interfaces:
    ASN1Encodable, Encodable
    public class SignedData
extends ASN1Object
    RFC 5652:

    A signed data object containing multitude of SignerInfos. 

     SignedData ::= SEQUENCE {
     version CMSVersion,
     digestAlgorithms DigestAlgorithmIdentifiers,
     encapContentInfo EncapsulatedContentInfo,
     certificates [0] IMPLICIT CertificateSet OPTIONAL,
     crls [1] IMPLICIT CertificateRevocationLists OPTIONAL,
     signerInfos SignerInfos
   }
 
 DigestAlgorithmIdentifiers ::= SET OF DigestAlgorithmIdentifier
 
 SignerInfos ::= SET OF SignerInfo

    The version calculation uses following ruleset from RFC 5652 section 5.1: 

     IF ((certificates is present) AND
    (any certificates with a type of other are present)) OR
    ((crls is present) AND
    (any crls with a type of other are present))
 THEN version MUST be 5
 ELSE
    IF (certificates is present) AND
       (any version 2 attribute certificates are present)
    THEN version MUST be 4
    ELSE
       IF ((certificates is present) AND
          (any version 1 attribute certificates are present)) OR
          (any SignerInfo structures are version 3) OR
          (encapContentInfo eContentType is other than id-data)
       THEN version MUST be 3
       ELSE version MUST be 1

      • getInstance

        public static SignedData getInstance​(java.lang.Object o)
        Return a SignedData object from the given object.

        Accepted inputs:

        Parameters:
        o - the object we want converted.
        Returns:
        a reference that can be assigned to SignedData (may be null)
        Throws:
        java.lang.IllegalArgumentException - if the object cannot be converted.
