获取证书的指纹

Question

我想将证书的指纹存储在如下变量中:

$thumbprint = 0F273F77B77E8F60A8B5B7AACD032FFECEF4776D

但我的命令输出是:

Get-ChildItem -Path Cert:\LocalMachine\My | Where-Object {$_.Subject -match "XXXXXXX"} 

Thumbprint                                Subject                                                                                                                     
----------                                -------                                                                                                                     
0F273F77B77E8F60A8B5B7AACD032FFECEF4776D  CN=XXXXXXX, OU=YYYYYYY 

我需要删除除输出的指纹之外的所有内容

任何的想法？

Answer 1

您所要做的就是将命令包装在括号中,然后使用点符号来访问该Thumbprint属性.

试试这个:

$Thumbprint = (Get-ChildItem -Path Cert:\LocalMachine\My | Where-Object {$_.Subject -match "XXXXXXX"}).Thumbprint;
Write-Host -Object "My thumbprint is: $Thumbprint";

如果从命令中获得多个证书,则必须使用-joinPowerShell运算符将指纹连接成单个字符串.

$Thumbprint = (Get-ChildItem -Path Cert:\LocalMachine\My | Where-Object {$_.Subject -match "XXXXXXX"}).Thumbprint -join ';';
Write-Host -Object "My thumbprints are: $Thumbprint";

Answer 2

您可以使用Select-Object仅获取Thumbprint- 属性：

Get-ChildItem -Path Cert:\LocalMachine\My | 
    Where-Object {$_.Subject -match "XXXXXXX"} | 
    Select-Object -ExpandProperty Thumbprint
