算法HmacPBESHA256不可用

Question

因此，我编写了一些代码来获取PEM，通过bouncycastle将其添加到PKCS密钥库中，然后使用Java crypto将PKCS密钥库值导入到JKS密钥库中。

[我发誓昨天我已经成功执行了这些步骤，并且通过了单元测试，但是今天早上我开始尝试了此步骤

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，总有可能在我下面改变某些东西，但我无法弄清楚那是什么。看来，我过去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

代码没有很多。首先，我通过Bouncycastle创建PKCS密钥库，添加一个pem并将其另存为PKCS12。然后通过java crypto导入，另存为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));
        }
    }

和它爆炸的繁荣

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

如您所见，BouncyCastleProvider已显式添加。有什么建议么？

更新：谢谢dave_thompson_085的建议。不敢相信我没有看到该重载方法，但是解决方案是在调用get Keystore.getInstance（“ PKCS12”，“ BC”）中指定提供程序。

Answer 1

正如dave_thompson_085指出的那样，我可以指定要用于密钥库的提供程序。我最初没有意识到这一点，因为我错过了getInstance（）重载。

因此，总结起来，这解决了我的问题：

KeyStore.getInstance("PKCS12","BC")

太容易了。

Answer 2

或者，标准Java（SunJCE Provider）HmacPBESHA256支持starting from Java 12算法。
