java.lang.Object org.bouncycastle.cms.CMSContentInfoParser org.bouncycastle.cms.CMSSignedDataParser
public class CMSSignedDataParser
Parsing class for an CMS Signed Data object from an input stream.
Note: that because we are in a streaming mode only one signer can be tried and it is important that the methods on the parser are called in the appropriate order.
A simple example of usage for an encapsulated signature.
Two notes: first, in the example below the validity of the certificate isn't verified, just the fact that one of the certs matches the given signer, and, second, because we are in a streaming mode the order of the operations is important.
CMSSignedDataParser sp = new CMSSignedDataParser(encapSigData); sp.getSignedContent().drain(); CertStore certs = sp.getCertificatesAndCRLs("Collection", "BC"); SignerInformationStore signers = sp.getSignerInfos(); Collection c = signers.getSigners(); Iterator it = c.iterator(); while (it.hasNext()) { SignerInformation signer = (SignerInformation)it.next(); Collection certCollection = certStore.getMatches(signer.getSID()); Iterator certIt = certCollection.iterator(); X509CertificateHolder cert = (X509CertificateHolder)certIt.next(); System.out.println("verify returns: " + signer.verify(new JcaSimpleSignerInfoVerifierBuilder().setProvider("BC").build(cert))); }Note also: this class does not introduce buffering - if you are processing large files you should create the parser with:
CMSSignedDataParser ep = new CMSSignedDataParser(new BufferedInputStream(encapSigData, bufSize));where bufSize is a suitably large buffer size.
