Class SignedData

org.bouncycastle.asn1.ASN1Object
org.bouncycastle.asn1.cms.SignedData
- All Implemented Interfaces:
ASN1Encodable
,Encodable
RFC 5652:
A signed data object containing multitude of SignerInfo
s.
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
