Powershell export local store certificate to pfx without password enters password

powershell

using certutil is pretty straight forward:

certutil -exportpfx -p "" my serialnr path\to\hostname.pfx noroot

I need to convert it from pfx to pem, so I need to do some scripting. This is what I have so far:

   $output = ( certutil -store my | findstr /i seri )
   $separator = ":"
   $serialstring = $output.split( $separator )
   $serialnr = $serialstring[1]
   $exportpfx = "certutil -exportpfx -p `"`" my" + $serialnr + " path\to\"+$env:computername+".pfx noroot" 
   invoke-expression $exportpfx

This nearly works, but the resulting pfx file has a password. So apparently my $exportpfx var is saving more info than it should, but I cannot see what.

Any tips? Thanks!

since I my goal was to convert the pfx to pem, I used the openssl tools for windows to remove the key after the creation of the pfx

Powershell Export-Clixml object manipulation

You're not missing anything. export-clixml/import-clixml only exports properties (i.e. no methods), and the imported object has a slightly different type.

Here's some code that illustrates the issue:

$a=dir c:\temp\blogs.html
$a.PSObject.TypeNames
$a | Export-Clixml C:\temp\file.xml

$b=import-clixml c:\temp\file.xml
$b.PSObject.TypeNames

Note that $a is a System.IO.FileInfo, but $b is a Deserialized.System.IO.FileInfo.

Powershell – How to Handle Null Objects in Foreach Loop

This is a "feature" of Powershell. Your $backups may contain multiple $null values, as well as non-null, so Powershell must iterate the object to process the foreach. The fact the we both see $backup as a single-value scalar ($null in this case) doesn't matter, to MS at least... :)

See this Microsoft Connect Bug Report for more details -- It is "fixed" in Powershell v3.

On v2:

PS H:\> foreach ( $i in $null ) { "Hi" }
Hi

On v3:

PS H:\> foreach ( $i in $null ) { "Hi" }

(No output)
