数据加密解密工具类

操作简单，提供加密解密 Api  
直接参考sample的代码
 
    switch (view.getId()) {
        case R.id.btn1://加密
            try {
                String encrypt = DES3.encrypt(KEY2, get());
                mTemp = encrypt;
                mTextView2.append("\r\n加密:"+encrypt);
            } catch (Exception e) {
                e.printStackTrace();
            }
            break;
        case R.id.btn2://解密

            try {
                String decrypt = DES3.decrypt(KEY2, mTemp);
                mTextView2.append("\r\n解密:"+decrypt);
            } catch (Exception e) {
                e.printStackTrace();
            }
            break;
    }
