Question

我的应用程序的一些代码在android中创建了一个密钥库，创建一些默认密钥然后保存密钥库。

稍后代码尝试在模拟器上重新加载密钥库运行正常但是当在手机上运行时我得到EOFException。任何关于我哪里出错的建议？

下面是代码：

在课堂上，我有以下变量

static KeyStore keyStore; 
String filenameKeyStore = "KeyStore.kstore";

然后是以下两个函数

    public KeyHandler(Context context) { 
                if(keyStore == null) { 
                        Log.d("KeyStore", "Keystore is null so loading"); 
                        if(initialiseKeyStore(context) == false) { 
                                // KeyStore failed to initialise 
                                Log.e("ERROR", "Store failed to initialise"); 
                        } 
                } 
        } 
private boolean initialiseKeyStore(Context context) { 
                FileInputStream input = null; 
                try { 
                        // Get an instance of KeyStore 
                        keyStore = KeyStore.getInstance("BKS"); 
                        // Load the KeyStore file 
                        try { 
                                // Try and open the private key store 
                                input = context.openFileInput(filenameKeyStore); 
                        } catch (FileNotFoundException e) { 
                                // If  the file doesn't exist then create the file, a ECDH key and 
store the key 
                                Log.w("Warning","File does not exist, creating new file"); 
                                try { 
                                        // Load the default Key Store 
                                        keyStore.load(null, null); 
                                        // Create the file 
                                        FileOutputStream output = 
context.openFileOutput(filenameKeyStore, 0); 
                                        // Reset private key 
                                        resetPrivateKey(context); 
                                        // Save the key 
                                        keyStore.store(output, "password".toCharArray()); 
                                        // Close the keystore and set the input stream 
                                        output.close(); 
                                        input = context.openFileInput(filenameKeyStore); 
                                        // Reset the keyStore

这通常在密钥库文件损坏时发生。我们刚刚（再次）有一个外部开发人员发送的密钥库这样的问题，他无法回想起他是如何创建密钥库文件的。

创建一个新的密钥库文件并导入证书 - 这将解决问题。

KeyStore加载导致Android上出现EOFException错误
