我正在尝试加密和解密密码,到目前为止,这些生成 key 都很好。现在我需要将此 key 存储在属性文件中,但是当我添加 key 时,它看起来像这样:

#Tue Nov 01 08:22:52 EET 2016
KEY=\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000

所以我怀疑我的代码可能有问题吗?!?!

我的代码中有一部分=
private byte[] key = new byte[16];

public void addProperties(String x, String z) {
    Properties properties = new Properties();
    String propertiesFileName = "config.properties";
    try {
        OutputStream out = new FileOutputStream(propertiesFileName);
        properties.setProperty(x, z);
        properties.store(out, null);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public void generateKey() {
    KeyGenerator keygen;
    SecretKey secretKey;
    byte[] keybyte = new byte[64];
    try {
        keygen = KeyGenerator.getInstance("AES");
        keygen.init(128);
        secretKey = keygen.generateKey();
        keybyte = secretKey.getEncoded();
        key = keybyte;

 //THIS METHOD ADDING PROP TO PROPERTIES FILE
        addProperties("KEY", new String(key));

    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }

}

感谢您的帮助。所有答案都可以接受。

最佳答案

KeyGenerator#generateKey()从Javadocs返回的类型为 SecretKey



So you need to convert them and there is already asked question on this
String encodedKey = Base64.getEncoder().encodeToString(secretKey.getEncoded());SecretKey originalKey = new SecretKeySpec(decodedKey, 0, decodedKey.length, "AES");
