PowerShell从Cer文件中复制证书内容

Cer文件是一段包含base64证书内容的字符串，用记事本打开，可能是这样：

-----BEGIN CERTIFICATE-----
MIIGPTCCBCWgAwIBAgITWgACJS12PP6tbgIWkQABAAIlLTANBgkqhkiG9w0BAQsF
.....
V4i3CeXHNPjD9orej/BVT2TcD9zfMckjpxDMZ+Pk1N73IpVgsgZEPJWss5Ck2z94
Bom9cGbG1oO92bnaZRbcUm4=
-----END CERTIFICATE-----

今天写一个函数，可以将有效的

#
# 
# Example: Get-DataFromCerFile D:\data\cert\pstips.net.cer
#
Function Get-DataFromCerFile
{
    param($CerFile)

    if( -not (Test-Path $CerFile)) {
        Write-Error "$CerFile 文件不存在."
    }
    elseif($CerFile -notlike '*.cer') {
        Write-Error "只支持Cert文件."
    }

    $rawFile = New-Object System.IO.FileInfo (Resolve-Path $CerFile).Path
    $certValueFile = "$rawFile.data.txt"

    $rawData = Get-Content $CerFile | Where-Object {
        ($_ -notmatch '-') -and (-not ([string]::IsNullOrWhiteSpace($_.ToString().Trim())))
    }
    $rawData -join '' | clip.exe
     Write-Host "证书内容以保存到剪贴板." -ForegroundColor Green
}
