请尝试（添加适当的检查并尝试省略的块以使代码更具可读性）这样的保存
public static void AESObjectEncoder(Serializable object, String password, String path) {
try {
Cipher cipher = null;
cipher = Cipher.getInstance("AES/CBC/PKCS7Padding");
cipher.init(Cipher.ENCRYPT_MODE, fromStringToAESkey(password));
SealedObject sealedObject = null;
sealedObject = new SealedObject(object, cipher);
CipherOutputStream cipherOutputStream = null;
cipherOutputStream = new CipherOutputStream(new bufferedoutputstream(new FileOutputStream(path)), cipher);
ObjectOutputStream outputStream = null;
outputStream = new ObjectOutputStream(cipherOutputStream);
outputStream.writeObject(sealedObject);
outputStream.close();
}
这要加载
public static Serializable AESObjectDedcoder(String password, String path) {
Cipher cipher = null;
Serializable userList = null;
cipher = Cipher.getInstance("AES/CBC/PKCS7Pdding");
//Code to write your object to file
cipher.init(Cipher.DECRYPT_MODE, fromStringToAESkey(password));
CipherInputStream cipherInputStream = null;
cipherInputStream = new CipherInputStream(new BufferedInputStream(new FileInputStream(path)), cipher);
ObjectInputStream inputStream = null;
inputStream = new ObjectInputStream(cipherInputStream);
SealedObject sealedObject = null;
sealedObject = (SealedObject) inputStream.readObject();
userList = (Serializable) sealedObject.getObject(ciper);
return userList;
}
public static SecretKey fromStringToAESkey(String s) {
//256bit key need 32 byte
byte[] rawKey = new byte[32];
// if you don't specify the encoding you might get weird results
byte[] keyBytes = new byte[0];
try {
keyBytes = s.getBytes("ASCII");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
System.arraycopy(keyBytes, 0, rawKey, 0, keyBytes.length);
SecretKey key = new SecretKeySpec(rawKey, "AES");
return key;
}
