Question

有没有办法获得与MySQL相同的结果

SELECT AES_ENCRYPT("text", "key")

使用Java函数？

如果可能的话，模拟AES_DECRYPT的另一个功能是什么。

Answer 1

好的，我已经设法让它像这样工作。

MySQL查询：

SELECT HEX(aes_encrypt("password", "0123456789012345"));

Java函数：

public static String aes_encrypt(String password, String strKey) {
    try {
        byte[] keyBytes = Arrays.copyOf(strKey.getBytes("ASCII"), 16);

        SecretKey key = new SecretKeySpec(keyBytes, "AES");
        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.ENCRYPT_MODE, key);

        byte[] cleartext = password.getBytes("UTF-8");
        byte[] ciphertextBytes = cipher.doFinal(cleartext);

        return new String(Hex.encodeHex(ciphertextBytes));

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } 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();
    } return null;
}

如果你需要解密算法的代码就在这里JAVA

 public static String aes_decrypt(String passwordhex, String strKey) throws Exception {
    try {
        byte[] keyBytes = Arrays.copyOf(strKey.getBytes("ASCII"), 16);

        SecretKey key = new SecretKeySpec(keyBytes, "AES");
        Cipher decipher = Cipher.getInstance("AES");

        decipher.init(Cipher.DECRYPT_MODE, key);

        char[] cleartext = passwordhex.toCharArray();

        byte[] decodeHex = Hex.decodeHex(cleartext);

        byte[] ciphertextBytes = decipher.doFinal(decodeHex);

        return new String(ciphertextBytes);

    } catch (Exception e) {
        e.getMessage();
    }
    return null;
}

它收到一个标准的十六进制格式字符串但是变量并返回密码。用主方法

进行测试

    System.out.println(aes_encrypt("your_string_password", "your_string_key"));
    System.out.println(aes_decrypt("standard_hex_format_string ", "your_string_key"));

仅用加密进行第一次测试，然后只用解密。顺便说一下，你必须安装＆＃39; commons-codec-1.6.jar＆＃39;所以你可以使用Hex类 http://commons.apache.org/proper/commons-codec/download_codec.cgi
