    To do this, you can use the following PowerShell cmdlets:

    $pfx_cert = get-content '<path_to_cert>' -Encoding Byte

    [System.Convert]::ToBase64String($pfx_cert) | Out-File '<path_to_file>'

    where:

    For example:

    $pfx_cert = get-content 'C:\cert.pfx' -Encoding Byte

    [System.Convert]::ToBase64String($pfx_cert) | Out-File 'C:\base64.txt'
