## org.bouncycastle.asn1.cms
Class SignedData

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

All Implemented Interfaces:
  ASN1Encodable, Encodable

public class SignedData
extends ASN1Object

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

Constructor Summary
`SignedData(ASN1Set digestAlgorithms, ContentInfo contentInfo, ASN1Set certificates, ASN1Set crls, ASN1Set signerInfos)`

Constructor Detail

### SignedData

    public SignedData(ASN1Set digestAlgorithms,
                      ContentInfo contentInfo,
                      ASN1Set certificates,
                      ASN1Set crls,
                      ASN1Set signerInfos)

Method Detail

### getInstance

    public static SignedData getInstance(java.lang.Object o)

  Return a SignedData object from the given object.

  Accepted inputs: null → null `SignedData` object `ASN1Sequence` input formats with SignedData structure inside

  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.

### getVersion

    public ASN1Integer getVersion()

### getDigestAlgorithms

    public ASN1Set getDigestAlgorithms()

### getEncapContentInfo

    public ContentInfo getEncapContentInfo()

### getCertificates

    public ASN1Set getCertificates()

### getCRLs

    public ASN1Set getCRLs()

### getSignerInfos

    public ASN1Set getSignerInfos()

### toASN1Primitive

    public ASN1Primitive toASN1Primitive()

  Produce an object suitable for an ASN1OutputStream.

  Specified by:
    `toASN1Primitive` in interface `ASN1Encodable`
  Specified by:
    `toASN1Primitive` in class `ASN1Object`
  Returns:
    a primitive representation of this object.
