Request-Certificate

Requests a certificates with the specified subject name from am Windows CA and saves the resulting certificate with the private key in the local computer store.

You must specify at least the CN for the subject name.

With the SAN parameter you can also specify values for subject alternative name to request a SAN certificate.
The CA must support this type of certificate otherwise the request will fail.

With the Export parameter it's also possible to export the requested certificate (with private key) directly to a .pfx file instead of storing it in the local computer store.

You can also use the Import-CSV cmdlet with Request-Certificate.ps1 to request multiple certificates.
To do this, use the Import-CSV cmdlet to create custom objects from a comma-separated value (CSV) file that contains a list of object properties (such as CN, SAN etc. ). Then pass these objects through the pipeline to Request-Certificate.ps1 to request the certificates.
