使用：
string IPassword = MD5Help.MD5Encrypt(password, ConfigurationManager.AppSettings["sKey"].ToString()); //加密 後面的參數是密鑰
string JPassword = MD5Help.MD5Decrypt(Password, ConfigurationManager.AppSettings["sKey"].ToString()); //解密 後面的參數是密鑰
webConfig配置：
<!--Md5加密key-->
<add key="sKey" value="JUNDAOXT"/>
