Export a Base-64 x.509 Cert using PowerShell on Windows 7

Exporting a Base-64 Encoded x.509 certificate using PowerShell is trivial if you have the Export-Certificate cmdlet available. However, many of the nodes I work with are Windows 7 which unfortunately doesn’t include these cmdlets. Therefore I needed an alternate method of exporting these Base-64 encoded x.509 certificates from these nodes.

So I came up with this little snippet of code:

	$certificate = Get-ChildItem -Path Get-ChildItem -path Cert:\CurrentUser\My\D675AE3AE9F7B56348C17EE527F261CFCEA0FD13
	$base64certificate = @"
	-----BEGIN CERTIFICATE-----
	$([Convert]::ToBase64String($certificate.Export('Cert'), [System.Base64FormattingOptions]::InsertLineBreaks)))
	-----END CERTIFICATE-----
	"@
	Set-Content -Path "$ENV:USERPROFILE\Documents\MyCert.cer" -Value $base64certificate
