我已经尝试了几天，我无可救药地被困住了。为了完全理解 java 密钥库的工作原理，我一直在尝试创建自己的密钥库，在其中放入一些东西，然后从另一个程序中检索它们。

这是我的密钥库生成器：

{

    //generate a X509 certificate
    Security.addProvider(new BouncyCastleProvider());
    CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509", "BC");
    X509Certificate certificate = (X509Certificate) certificateFactory.generateCertificate(new FileInputStream("certificate.cer"));

    LOGGER.debug("BouncyCastle provider & X509 certificate added.");

    //generate a private & a public key
    KeyPair keyPair = generateRSAKeyPair();
    RSAPrivateKey priv = (RSAPrivateKey) keyPair.getPrivate();
    RSAPublicKey pub = (RSAPublicKey) keyPair.getPublic();

    //generate a keystore
    KeyStore ks = KeyStore.getInstance("PKCS12");
    char[] keyStorePassword = "keystore_password".toCharArray();
    ks.load(null, keyStorePassword);
    try (FileOutputStream fos = new FileOutputStream("TestKeyStore.jks")) {
        ks.store(fos, keyStorePassword);
    }

    ks.load(new FileInputStream("TestKeyStore.jks"), keyStorePassword);

    //Symmetric key
    SecretKey secretKey = …
