使用证书签名PowerShell脚本

1.创建自签名证书（如需要）

PS C:\Windows\system32> New-SelfSignedCertificate -DnsName www.mycard.com -CertStoreLocation Cert:\CurrentUser\My


    目录: Microsoft.PowerShell.Security\Certificate::CurrentUser\My


Thumbprint                                Subject
----------                                -------
313C6D95807E577BBD62D3F0A31077C911B72EB6  CN=www.mycard.com

2.获取证书

    a).查找证书存储位置

PS C:\Windows\system32> Get-PSDrive

Name           Used (GB)     Free (GB) Provider      Root
----           ---------     --------- --------      ----
Alias                                  Alias
C                  44.32         16.86 FileSystem    C:Cert                                   Certificate   \

PS C:\Windows\system32> dir Cert:\CurrentUser\My -OutVariable x


    目录: Microsoft.PowerShell.Security\Certificate::CurrentUser\My


Thumbprint                                Subject
----------                                -------
C744543541A7B9E5E0085F38351727765A716415  CN=domain\user
313C6D95807E577BBD62D3F0A31077C911B72EB6  CN=www.mycard.com

PS C:\Windows\system32> $x[0]


    目录: Microsoft.PowerShell.Security\Certificate::CurrentUser\My


Thumbprint                                Subject
----------                                -------
C744543541A7B9E5E0085F38351727765A716415  CN=domain\user

3.脚本签名前后

PS C:\Windows\system32> cat E:\1.ps1
Get-Variable

PS C:\Windows\system32> Set-AuthenticodeSignature -Certificate $x[0] -FilePath ‘E:\1.ps1‘


    目录: E:

SignerCertificate                         Status                                 Path

FBD0E44E1011C4C992CD5004D73137A3EC0E5AE4  Valid                                  1.ps1

PS C:\Windows\system32> cat E:\1.ps1
