XOR Cipher加密与我的GUI搞混了？

Question

我已经设置了一个简单的GUI系统来使用这个XOR加密系统。当我通过GUI解密时，解密出错是错误的，但是当我对字符串进行硬编码以解密时，它就出来了。例如：

例如，这会打印＆＃34; this_is_to_test_if_the_program_in_the_gui_is_working_which_it_wont＆＃34;：

System.out.println(Skeleton.xorDecrypt("BX_Dg_CgLVkCVKLfQUfC^SgHFWSFY^oP]iBPShSC]g^KgO[D\\Q]Qg@PQTPk^MiA_VD", "638460047789894"));

但是，如果我通过GUI进行操作，它就会显示为＆＃34; this_is_to_test_if_the_program_in_the_gui_is_workdiia_xdglf \ g {Qykns＆＃34;

Skeleton.java

public class Skeleton {

    public static String xorEncrypt(String data, String key) {

        data = data.replaceAll(" ", "_");

        byte m_cData[] = data.getBytes();
        byte m_cKey[] = key.getBytes();

        int keyPointer = 0;
        for (int i = 0; i < m_cData.length; i++) {
            m_cData[i] ^= m_cKey[keyPointer];
            keyPointer += m_cData[i];
            keyPointer %= m_cKey.length;
        }

        return new String(m_cData).replaceAll("\\\\", "\\\\\\\\");
    }

    public static String xorDecrypt(String data, String key) {
        byte m_cData[] = data.getBytes();
        byte m_cKey[] = key.getBytes();

        int keyPointer = 0;
        byte keyPointerAdd = 0;
        for (int i = 0; i < m_cData.length; i++) {
            keyPointerAdd = m_cData[i];
            m_cData[i] ^= m_cKey[keyPointer];
            keyPointer += keyPointerAdd;
            keyPointer %= m_cKey.length;
        }

        return new String(m_cData);
    }

    public static long generateRandom(int length) {
        Random random = new Random();
        char[] digits = new char[length];
        digits[0] = (char) (random.nextInt(9) + '1');
        for (int i = 1; i < length; i++) {
            digits[i] = (char) (random.nextInt(10) + '0');
        }
        return Long.parseLong(new String(digits));
    }

}
