以下代码：

//used Bouncy Castle provider for keyStore
keyStore.setKeyEntry(alias, (Key)keyPair.getPrivate(), pwd, certChain);

其中 certChain 持有最终证书和颁发者证书（即两个证书），
如果 keyStore 是PKCS12.

如果密钥库类型为 ，它会保存两个证书PKCS12-3DES-3DES。为什么是这样？PKCS12 不认为两个证书都是链的一部分吗？

编辑：这是一个SSCCE。这适用于"JKS"，失败"PKCS12"： 只有链中的第一个证书可以通过getCertificateChain(String). 保存的文件可以在openssl pkcs12显示两个证书的情况下打开。

    public void testKeyStore() {
    try {
        KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
        keyPairGenerator.initialize(1024);
        KeyPair keyPair = keyPairGenerator.generateKeyPair();
        PublicKey publicKey = keyPair.getPublic();
        PrivateKey privateKey = keyPair.getPrivate();
        Certificate[] outChain = { createCertificate("CN=CA", publicKey, privateKey), createCertificate("CN=Client", publicKey, privateKey) };

        KeyStore outStore = KeyStore.getInstance("PKCS12");
        outStore.load(null, "secret".toCharArray());
        outStore.setKeyEntry("mykey", privateKey, "secret".toCharArray(), outChain);            
        OutputStream outputStream = new FileOutputStream("c:/outstore.pkcs12");
        outStore.store(outputStream, "secret".toCharArray());
        outputStream.flush();
        outputStream.close();

        KeyStore inStore = KeyStore.getInstance("PKCS12");      
        inStore.load(new FileInputStream("c:/outstore.pkcs12"), "secret".toCharArray());
        Key key = outStore.getKey("myKey", "secret".toCharArray());
        assertEquals(privateKey, key);

        Certificate[] inChain = outStore.getCertificateChain("mykey");
        assertNotNull(inChain);
        assertEquals(outChain.length, inChain.length);
    } catch (Exception e) {
        e.printStackTrace();
        fail(e.getMessage());
    }
}

private static X509Certificate createCertificate(String dn, PublicKey publicKey, PrivateKey privateKey) throws Exception {
    X509V3CertificateGenerator certGenerator = new X509V3CertificateGenerator();
    certGenerator.setSerialNumber(new BigInteger("1"));
    certGenerator.setIssuerDN(new X509Name(dn));
    certGenerator.setSubjectDN(new X509Name(dn));
    certGenerator.setNotBefore(Calendar.getInstance().getTime());
    certGenerator.setNotAfter(Calendar.getInstance().getTime());
    certGenerator.setPublicKey(publicKey);
    certGenerator.setSignatureAlgorithm("SHA1withRSA");
    X509Certificate certificate = (X509Certificate)certGenerator.generate(privateKey, "BC");
    return certificate;
}

您的代码有 2 个错误：

首先：您没有为证书设置颁发者（客户端证书应由 CA 颁发以建立有效的链）。

第二：创建证书链时使用错误的顺序（应该是客户端证书，最后是CA）

这里是重新设计的 SSCCE，它可以正常工作。

@Test
public void testKeyStore() throws Exception{
        try {
        String storeName =  "/home/grigory/outstore.pkcs12";

        PrivateKey privateKey = keyPair.getPrivate();
        Certificate trustCert =  createCertificate("CN=CA", "CN=CA", publicKey, privateKey);
        Certificate[] outChain = { createCertificate("CN=Client", "CN=CA", publicKey, privateKey), trustCert };

        KeyStore outStore = KeyStore.getInstance("PKCS12");
        outStore.load(null, "secret".toCharArray());
        outStore.setKeyEntry("mykey", privateKey, "secret".toCharArray(), outChain);

根据您使用的 JDK，有不同的方式来打包您的应用程序。当一些人使用 Linux 和 OpenJDK 以及其他一些人在 Windows 上使用 SunJDK (Oracle) 进行开发时，就会发生这种情况。

最新的有一些额外的配置，以便能够使用最强的算法。如果您的问题与 JCE 政策有关，本文可以为您提供帮助。
