我正在开发一个安卓应用程序。不幸的是我有一个兼容性问题。我的源代码适用于固件 4.1,但使用固件 2.2 的设备会崩溃。该错误似乎是由 ObjectInputStream 引起的“ClassNotFoundException”。
我的加密和解密源代码:
private Key getPublicKey() {
try {
InputStream fis = activity.getResources().openRawResource(R.raw.publick);
ObjectInputStream ois = new ObjectInputStream(fis);
Key RSApublicKey = (Key) ois.readObject();
return RSApublicKey;
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
catch (ClassNotFoundException e) {
e.printStackTrace();
}
return null;
}
private Key getPrivateKey() {
try {
InputStream fis = activity.getResources().openRawResource(R.raw.privatek);
ObjectInputStream ois = new ObjectInputStream(fis);
Key RSAprivateKey = (Key) ois.readObject();
return RSAprivateKey;
}
catch (FileNotFoundException e) {
e.printStackTrace();
}
catch (IOException e) {
e.printStackTrace();
}
catch (ClassNotFoundException e) {
Log.e("error", "Error: " + e);
e.printStackTrace();
}
return null;
}
public byte[] encrypt(String data) {
byte[] encrypted = null;
try {
Cipher cipher = Cipher.getInstance("RSA");
cipher.init(Cipher.ENCRYPT_MODE, getPublicKey());
encrypted = cipher.doFinal(data.getBytes());
}
catch (IllegalBlockSizeException e) {
e.printStackTrace();
}
catch (BadPaddingException e) {
e.printStackTrace();
}
catch (InvalidKeyException e) {
e.printStackTrace();
}
catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
catch (NoSuchPaddingException e) {
e.printStackTrace();
}
catch (NoSuchProviderException e) {
e.printStackTrace();
}
return encrypted;
}
public String decrypt(byte[] encrypted) {
byte[] decrypted = null;
try {
Cipher cipher;
cipher = Cipher.getInstance("RSA");
cipher.init(Cipher.DECRYPT_MODE, getPrivateKey());
decrypted = cipher.doFinal(encrypted);
}
catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
catch (NoSuchPaddingException e) {
e.printStackTrace();
}
catch (InvalidKeyException e) {
e.printStackTrace();
}
catch (IllegalBlockSizeException e) {
e.printStackTrace();
}
catch (BadPaddingException e) {
e.printStackTrace();
}
catch (NoSuchProviderException e) {
e.printStackTrace();
}
return new String(decrypted);
}
logcat中的错误:
03-23 10:13:19.706: E/Error(427): Error: java.lang.ClassNotFoundException: com.android.org.bouncycastle.jce.provider.JCERSAPrivateCrtKey
你有什么想法,我怎样才能让它与 android 2.2 一起工作?
