Java function for Encrypt/Decrypt like Mysql's AES_ENCRYPT and AES_DECRYPT

Is there any way to get the same result as doing in MySQL

SELECT AES_ENCRYPT("text", "key") 

using a Java fu开发者_JS百科nction?

And if possible, what's the other function to simulate the AES_DECRYPT.

If you need the code to decrypt the algorithm is here 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;
}

It received a standard hex format string but variable and returns the password. Test with those in main method

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

firstable test only with encrypt, then just with decrypt. By the way you must install 'commons-codec-1.6.jar' so you can use the Hex class http://commons.apache.org/proper/commons-codec/download_codec.cgi

Greetings from Ecuador, Ibarra

Ok, I've managed to get it working like this.

MySQL Query:

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

Java function:

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;
}

in my case i just code like this

 private static final char[] HEX_ARRAY = "0123456789ABCDEF".toCharArray();
    public static String bytesToHex(byte[] bytes) {
    char[] hexChars = new char[bytes.length * 2];
    for (int j = 0; j < bytes.length; j++) {
        int v = bytes[j] & 0xFF;
        hexChars[j * 2] = HEX_ARRAY[v >>> 4];
        hexChars[j * 2 + 1] = HEX_ARRAY[v & 0x0F];
    }
    return new String(hexChars);
 }

and than create method aes 128

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(bytesToHex(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;
}

example : mysql code

SELECT HEX(aes_encrypt("text", "0123456889812345"))

java code

System.out.println(aes_encrypt("text", "0123456889812345"));
