Question

使用Java和BouncyCastle，我可以解密许多S / MIME封装消息。

但是当密钥加密算法为1.2.840.113549.1.1.7（id-RSAES-OAEP）时，解密失败（此问题末尾的堆栈跟踪）。

发生的行：

content = messageRecipientInfo.getContent(new JceKeyTransEnvelopedRecipient(pc).setProvider("BC"));

以前我用这行来解密：

content = messageRecipientInfo.getContent(givenCertRecipient);

一切都一样。

有什么猜测吗？

编辑*

我现在尝试使用OAEP加密数据。因此，我在文件cms / test / NewEnvelopedDataTest.java中直接在BouncyCastle中找到了代码即便这样也行不通！同样的错误：

String BC = BouncyCastleProvider.PROVIDER_NAME;

KeyPair _reciKP = CMSTestUtil.makeKeyPair();
String _reciDN = "CN=Doug, OU=Sales, O=Bouncy Castle, C=AU";
KeyPair _signKP = CMSTestUtil.makeKeyPair();
String _signDN = "O=Bouncy Castle, C=AU";
X509Certificate _reciCertOaep = CMSTestUtil.makeOaepCertificate(_reciKP, _reciDN, _signKP, _signDN);

byte[] data = "WallaWallaWashington".getBytes();

CMSEnvelopedDataGenerator edGen = new CMSEnvelopedDataGenerator();

JcaAlgorithmParametersConverter paramsConverter = new JcaAlgorithmParametersConverter();

edGen.addRecipientInfoGenerator(new JceKeyTransRecipientInfoGenerator(_reciCertOaep).setProvider(BC));

edGen.addRecipientInfoGenerator(new JceKeyTransRecipientInfoGenerator(ASN1OctetString.getInstance(ASN1OctetString.getInstance(_reciCertOaep.getExtensionValue(Extension.subjectKeyIdentifier.getId())).getOctets()).getOctets(), _reciCertOaep.getPublicKey()).setProvider(BC));

在最后一步中崩溃：＆＃34;无法初始化算法参数：操作不受支持＆＃34;

CMSEnvelopedData edd = edGen.generate(
                new CMSProcessableByteArray(data),
                new JceCMSContentEncryptorBuilder(CMSAlgorithm.DES_EDE3_CBC).setProvider(BC).build());

有什么问题？我看不到......

使用OAEP密钥加密对S / MIME封装消息进行解密失败？
