经常用到的数字钱包很容易被病毒进行攻击,我们可以将钱包安装到外置U盘或者电脑SD卡，通过对U盘或SD卡进行Bitlocker加密，来达到加密数字钱包的功能，我们还可以将一些密钥放入bitlocker加密盘中。
1.加密U盘和SD卡

4.添加加密盘右键加密菜单
打开注册表新建项HKEY_CLASSES_ROOT\Drive\shell\runas，默认值改为LOCK
新建项HKEY_CLASSES_ROOT\Drive\shell\runas\command，默认值为c:\windows\System32\manage-bde.exe k: -lock
然后关闭注册表，选择k盘符将看到Lock快捷菜单，选择Lock，则K盘就会加密，重新打开则需要再次输入密码
