使用Power shell生成机器密钥

Question

我想生成机器关键的几个机之间共享,快速谷歌搜索后,我发现这个文章KB 2915218,附录A.

1. 我复制了代码并保存为.ps1扩展名,我相信是power shell扩展名.
2. 打开电源外壳
3. 移动到文件的位置
4. 运行脚本.

PS E:./Generate-MachineKey -validation sha1

它运行正常,但它不输出密钥.有什么理由吗？我在Powershell做错了吗？

谢谢,

Answer 1

该脚本包含一个函数,因此您必须首先加载脚本,然后运行该函数才能使其工作.

首先我们必须加载文件,我打电话给我的ps1"MachineKey"所以这就是我加载它的方式

PS E:\> . .\MachineKey.ps1

一旦我加载了文件,如果我想运行名为"Generate-MachineKey"的函数,我必须在之后输入

PS E:\> Generate-MachineKey -validationAlgorithm SHA1

Answer 2

它的方式比我想象的要容易：不需要保存 .ps1 文件，只需粘贴脚本并运行它。我在本地 PC 上，以管理员身份使用 Win 8.1。

以管理员身份打开 PowerShell。

在下一行输入此命令

PS C:\Users\JM> Generate-MachineKey
<machineKey decryption="AES" decryptionKey="xxxxxxxxxxxxxxxxxxxx" validation="HMACSHA256" validationKey="xxxxxxxxxxxxxxxxx" />
