java.lang.Objectorg.bouncycastle.asn1.ASN1Object
org.bouncycastle.asn1.cms.SignedData
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
