Class CMSSignedData
java.lang.Object
org.bouncycastle.cms.CMSSignedData
public class CMSSignedData
extends java.lang.Object
general class for handling a pkcs7-signature message.
A simple example of usage - note, in the example below the validity of
the certificate isn't verified, just the fact that one of the certs
matches the given signer...
CertStore certs = s.getCertificatesAndCRLs("Collection", "BC");
SignerInformationStore signers = s.getSignerInfos();
Collection c = signers.getSigners();
Iterator it = c.iterator();
while (it.hasNext())
{
SignerInformation signer = (SignerInformation)it.next();
Collection certCollection = certs.getCertificates(signer.getSID());
Iterator certIt = certCollection.iterator();
X509Certificate cert = (X509Certificate)certIt.next();
if (signer.verify(cert.getPublicKey()))
{
verified++;
}
}

public CMSSignedData(ContentInfo sigData)
CMSSignedData
public CMSSignedData(InputStream sigData)
throws CMSException
base constructor - with encapsulated content
CMSSignedData
public CMSSignedData(byte[] sigBlock)
throws CMSException
CMSSignedData
public CMSSignedData(CMSProcessable signedContent,
ContentInfo sigData)
CMSSignedData
public CMSSignedData(CMSProcessable signedContent,
InputStream sigData)
throws CMSException
base constructor
signedContent
- the content that was signed.sigData
- the signature object.
getCertificatesAndCRLs
public CertStore getCertificatesAndCRLs(String type,
String provider)
throws NoSuchAlgorithmException,
NoSuchProviderException,
CMSException
return a CertStore containing the certificates and CRLs associated with
this message.
getEncoded
public byte[] getEncoded()
throws IOException
return the ASN.1 encoded representation of this object.
getSignedContentTypeOID
public String getSignedContentTypeOID()
Return the a string representation of the OID associated with the
encapsulated content info structure carried in the signed data.
- the OID for the content type.
getSignerInfos
public SignerInformationStore getSignerInfos()
return the collection of signers that are associated with the
signatures for the message.
replaceCertificatesAndCRLs
public static CMSSignedData replaceCertificatesAndCRLs(CMSSignedData signedData,
CertStore certsAndCrls)
throws CMSException
Replace the certificate and CRL information associated with this
CMSSignedData object with the new one passed in.
signedData
- the signed data object to be used as a base.certsAndCrls
- the new certificates and CRLs to be used.
- a new signed data object.
CMSException
- if there is an error processing the CertStore
replaceSigners
public static CMSSignedData replaceSigners(CMSSignedData signedData,
SignerInformationStore signerInformationStore)
Replace the signerinformation store associated with this
CMSSignedData object with the new one passed in. You would
probably only want to do this if you wanted to change the unsigned
attributes associated with a signer, or perhaps delete one.
signedData
- the signed data object to be used as a base.signerInformationStore
- the new signer information store to use.
- a new signed data object.
