Java BouncyCastle属性messageDigest验证失败

我在使用BouncyCastle1.59签名/veryfing CADES签名时遇到问题。 我必须添加messageDigest属性，但当我添加它时，我的程序失败了

这是我的密码：

Signature signature = Signature.getInstance("SHA256withRSA", new BouncyCastleProvider());
byte[] test_data = "test".getBytes();
MessageDigest dig = MessageDigest.getInstance("SHA256", new BouncyCastleProvider());
byte[] digest = dig.digest(test_data);

byte[] privateKeyContent = archivePrivateKey.getBytes();
BufferedReader br = new BufferedReader(new InputStreamReader(new ByteArrayInputStream(privateKeyContent)));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();

signature.initSign(kp.getPrivate());
signature.update(test_data);

byte[] certContent = archiveCertificateContent.getBytes();
PemFile pemFile = new PemFile(certContent);
X509CertificateHolder cert = new X509CertificateHolder(pemFile.getPemObject().getContent());
X509Certificate certificate = new JcaX509CertificateConverter().getCertificate(cert);

// Build CMS
List certList = new ArrayList();
CMSTypedData data = new CMSProcessableByteArray(signature.sign());
certList.add(certificate);
Store certs = new JcaCertStore(certList);


byte[] certHash = dig.digest(certificate.getEncoded());
AlgorithmIdentifier algId = new AlgorithmIdentifier(NISTObjectIdentifiers.id_sha256);
ESSCertIDv2 essCert = new ESSCertIDv2(algId, certHash);
SigningCertificateV2 scv2 = new SigningCertificateV2(new ESSCertIDv2[] { essCert });

ASN1EncodableVector signedAttributes = new ASN1EncodableVector();
signedAttributes.add(new Attribute(PKCSObjectIdentifiers.id_aa_signingCertificateV2, new DERSet(scv2)));
//signedAttributes.add(new Attribute(CMSAttributes.messageDigest, new DERSet(new DEROctetString(digest))));
signedAttributes.add(new Attribute(CMSAttributes.contentType, new DERSet(PKCSObjectIdentifiers.data)));

AttributeTable signedAttributesTable = new AttributeTable(signedAttributes);
signedAttributesTable.toASN1EncodableVector();

CMSSignedDataGenerator gen = new CMSSignedDataGenerator();
JcaContentSignerBuilder contentSigner = new JcaContentSignerBuilder("SHA256withRSA");
contentSigner.setProvider(BC_PROVIDER);
SignerInfoGeneratorBuilder signerInfoBuilder = new SignerInfoGeneratorBuilder(new JcaDigestCalculatorProviderBuilder().setProvider(BC_PROVIDER).build());
signerInfoBuilder.setSignedAttributeGenerator(new DefaultSignedAttributeTableGenerator(signedAttributesTable));

gen.addSignerInfoGenerator(signerInfoBuilder.build(contentSigner.build(kp.getPrivate()), cert));
gen.addCertificates(certs);
CMSSignedData signedData = gen.generate(data, true);

// Verify signature
Store store = signedData.getCertificates();
SignerInformationStore signers = signedData.getSignerInfos();
Collection c = signers.getSigners();
Iterator it = c.iterator();
while (it.hasNext()) {
  SignerInformation signer = (SignerInformation) it.next();
  Collection certCollection = store.getMatches(signer.getSID());
  Iterator certIt = certCollection.iterator();
  X509CertificateHolder certHolder = (X509CertificateHolder) certIt.next();
  X509Certificate certFromSignedData = new JcaX509CertificateConverter().setProvider(BC_PROVIDER).getCertificate(certHolder);
  if (signer.verify(new JcaSimpleSignerInfoVerifierBuilder().setProvider(BC_PROVIDER).build(certFromSignedData))) {
    System.out.println("Signature verified");
  } else {
    System.out.println("Signature verification failed");
  }
}

当我取消注释第35行时：

signedAttributes.add（新属性（CMSAttributes.messageDigest，新DERSet（新DEROctetString（digest）））然后我得到错误：

org.bouncycastle.cms.CMSSignerDigestMismatchException:消息摘要属性值与计算值不匹配

我尝试了很多选项和配置，但问题仍然存在。任何帮助都是非常有用的。
谢谢
我自己还没有尝试过你的代码，但我认为问题在于你添加的消息摘要作为MessageDigest属性并不是你真正在SignedData中添加的内容。我看到您首先使用JCA对数据进行签名

Signature signature = Signature.getInstance("SHA256withRSA", new BouncyCastleProvider());
byte[] test_data = "test".getBytes();
    signature.initSign(kp.getPrivate());
signature.update(test_data);
CMSTypedData data = new CMSProcessableByteArray(signature.sign());
...
CMSSignedData signedData = gen.generate(data, true);

在这里，您要放置签名（而不是数据，这很奇怪）来生成CMSSignedData。因此，对于contentSigner，您的签名就是要签名的实际数据。但是，在MessageDigest属性中，您要放置实际数据的摘要。这很可能是造成问题的原因

现在来谈谈更重要的问题。首先，为什么要使用上述代码对数据进行签名？这在我看来是错误的，可能不是你想要的。如果您的目的是为“测试”数据生成CMS signedData，则应直接在signedData Generator中使用该数据，这将处理签名部分

如果您还没有这样做，请检查

希望这有帮助。
我删除了签名。initSign。。。part并允许signedDataGenerator对数据进行签名。然后它开始工作了。谢谢
