算法 HmacPBESHA256 不可用

因此，我编写了一些代码来获取 PEM，通过 bouncycastle 将其添加到 PKCS 密钥库，然后使用 java 加密将 PKCS 密钥库值导入 JKS 密钥库。

我发誓，昨天我成功地执行了这些步骤的单元测试通过，但今天早上我开始点击这个

Caused by: java.security.NoSuchAlgorithmException: Algorithm HmacPBESHA256 not available
    at javax.crypto.Mac.getInstance(Mac.java:181) ~[na:1.8.0_60]
    at sun.security.pkcs12.PKCS12KeyStore.engineLoad(PKCS12KeyStore.java:2039) ~[na:1.8.0_65]

现在，总是有可能在我下面有变化，但我不知道它是什么。似乎我用于该算法的任何提供程序都消失了。

这是我的java.security文件片段：

security.provider.1=sun.security.provider.Sun
security.provider.2=sun.security.rsa.SunRsaSign
security.provider.3=sun.security.ec.SunEC
security.provider.4=com.sun.net.ssl.internal.ssl.Provider
security.provider.5=com.sun.crypto.provider.SunJCE
security.provider.6=sun.security.jgss.SunProvider
security.provider.7=com.sun.security.sasl.Provider
security.provider.8=org.jcp.xml.dsig.internal.dom.XMLDSigRI
security.provider.9=sun.security.smartcardio.SunPCSC
security.provider.10=apple.security.AppleProvider

代码中没有很多内容。首先，我通过弹跳城堡创建一个PKCS密钥库，添加一个pem并作为PKCS12保存到磁盘。然后通过java加密导入，保存回JKS。

   public KeystoreBuilder createJksFromPem(String pemPrivate, String pemPublic, String alias) throws Exception
    {
        Preconditions.checkState(StringUtils.isNotEmpty(pemPrivate), "pemPrivate must not be empty");
        Preconditions.checkState(StringUtils.isNotEmpty(pemPublic), "pemPublic must not be empty");
        Preconditions.checkState(StringUtils.isNotEmpty(alias), "alias must not be empty");

        String pkcsFilename = filename + ".pkcs";
        convertPemToPkcs(pemPrivate, pemPublic, pkcsFilename);

        importPkcsIntoJks(pkcsFilename);

        return this;
    }

    private void importPkcsIntoJks(String pkcsFilename) throws Exception
    {
        KeyStore pkcs = KeyStore.getInstance("PKCS12");
        File pkcsFile = new File(pkcsFilename);
        try (FileInputStream fis = new FileInputStream(pkcsFile))
        {
            pkcs.load(fis, password.toCharArray());
        }
        pkcsFile.delete();

        KeyStore jks = KeyStore.getInstance("JKS");
        jks.load(null);

        Enumeration<String> aliases = pkcs.aliases();
        while (aliases.hasMoreElements())
        {
            String alias = aliases.nextElement();
            if (!pkcs.isKeyEntry(alias))
            {
                continue;
            }
            Key key = pkcs.getKey(alias, password.toCharArray());
            Certificate[] chain = pkcs.getCertificateChain(alias);

            jks.setKeyEntry(alias, key, password.toCharArray(), chain);
        }

        persist(jks);
    }

    private void convertPemToPkcs(String pemPrivate, String pemPublic, String pkcsFilename) throws IOException, NoSuchAlgorithmException, OperatorCreationException, PKCSException, FileNotFoundException
    {
        Security.addProvider(new BouncyCastleProvider());

        X509CertificateHolder cert = (X509CertificateHolder) readObject(pemPublic);
        PEMKeyPair keyPair = (PEMKeyPair) readObject(pemPrivate);

        JcaX509ExtensionUtils extUtils = new JcaX509ExtensionUtils();
        PKCS12SafeBagBuilder pkcs12BagBuilder = new PKCS12SafeBagBuilder(cert);
        pkcs12BagBuilder.addBagAttribute(PKCSObjectIdentifiers.pkcs_9_at_friendlyName, new DERBMPString("Kafka SSL Certificate"));
        pkcs12BagBuilder.addBagAttribute(PKCSObjectIdentifiers.pkcs_9_at_localKeyId, extUtils.createSubjectKeyIdentifier(keyPair.getPublicKeyInfo()));

        PKCS12PfxPduBuilder builder = new PKCS12PfxPduBuilder();

        builder.addData(pkcs12BagBuilder.build());

        builder.addEncryptedData(new JcePKCSPBEOutputEncryptorBuilder(PKCSObjectIdentifiers.pbeWithSHAAnd128BitRC2_CBC).setProvider("BC").build(password.toCharArray()), pkcs12BagBuilder.build());

        PKCS12PfxPdu pfx = builder.build(new JcePKCS12MacCalculatorBuilder(NISTObjectIdentifiers.id_sha256), password.toCharArray());

        try (FileOutputStream fos = new FileOutputStream(new File(pkcsFilename)))
        {
            fos.write(pfx.getEncoded(ASN1Encoding.DL));
        }
    }

和繁荣它爆炸

pkcs.load(fis, password.toCharArray());

如您所见，BouncyCastleProvider已明确添加。有什么建议吗？

更新：感谢dave_thompson_085的建议。不敢相信我没有看到那个重载的方法，但解决方案是在调用get Keystore.getInstance（“PKCS12”，“BC”）中指定提供程序。
