无法从 KeyStore 读取密钥

Question

我在使用 KeyStore 时遇到了一些问题。我将密钥添加到 KeyStore，但无法从那里获取。我的代码：

        try 
        {
            KeyGenerator keygen = KeyGenerator.getInstance("AES");
            SecureRandom random = new SecureRandom();
            keygen.init(128, random);
            SecretKey key = keygen.generateKey();
            KeyStore ks = KeyStore.getInstance("UBER", "BC");
            ks.load(null, pass);
            ks.store(new FileOutputStream(path), pass);
            ks.setKeyEntry(keyName, key, pass, null);
            System.out.println(ks.containsAlias(keyName));
            key = null;
            KeyStore ks1 = KeyStore.getInstance("UBER", "BC");
            ks1.load(new FileInputStream(path), pass);
            System.out.println(ks1.containsAlias(keyName));
        }

输出是：

true
false

似乎是密钥丢失或者我无法正确加载 KeyStore。你看到这里有什么错误吗？

Answer 1

您正在保存密钥库，然后再向其添加密钥。交换这两行：

        ks.store(new FileOutputStream(path), pass);
        ks.setKeyEntry(keyName, key, pass, null);

所以他们是：

        ks.setKeyEntry(keyName, key, pass, null);
        ks.store(new FileOutputStream(path), pass);
