今天再来更新一篇博客，同样也是关于PowerShell的应用，熟练使用PowerShell对于平时的工作很多时候能够起到意想不到的效果，很多事情换个思路往往会发现能够少走很多弯路，今天介绍的其实主要是PowerShell在证书方面的一些简单应用，对应的也是平时工作中用到的一个场景，在我们的生产环境中有很多很多张证书，有一些自签名的，也有很多从第三方公司申请的公网证书，这些证书平时我们都备份在一个公共的文件夹中，以备不时之需，久而久之，文件夹里存放的证书就已经不下百张了，而且各种文件夹穿插着放一下让整个文件夹的结构变得更加复杂。平时想把证书找出来要花不少时间，还要查看证书的属性一一验证。因此前段时间写了这个PowerShell的脚本来方便查询，这个脚本可以根据输入的文件夹路径以及证书的指纹信息，便利文件夹下所有证书的属性，来查询特定指纹的证书的详细信息以及路径，脚本内容如下
#Get-Pfxdata is only supported by PowerShell 4.0 or Higher
[cmdletbinding()]
param(
[parameter(Mandatory = $true, Position = 0)]
[string]$Thumbprint,
[parameter(Mandatory = $true, Position = 1)]
[string]$FolderPath,
[parameter(Mandatory = $false, Position = 2)]
$Password
)
if ($PSVersionTable.PSVersion.Major -lt 4)
{
Write-Warning "You need run the script on PowerShell 4.0 or Higher"
exit
}

#其实用FUllName就可以直接实现了
foreach ($scp in $ShortCertPath) {

}
#====================================================================
#密码是个可选参数，这里设置了默认密码的值，如果有统一密码可以在脚本里***那个位置将密码填上

{
$Password = ConvertTo-SecureString -AsPlainText $Password -Force

$Password = ConvertTo-SecureString -AsPlainText "***" -Force

}总体来说脚本很简单，实现的功能也不复杂，主要是来看一下PowerShell在证书这方面的一些基本应用，有需要的话可以将各种语句自由组合在一起，实现想要的功能
