   $cert = New-SelfSignedCertificate -Type Custom -KeySpec Signature `
   -Subject "CN=P2SRootCert" -KeyExportPolicy Exportable `  -HashAlgorithm sha256 -KeyLength 2048 `
  -CertStoreLocation "Cert:\CurrentUser\My" -KeyUsageProperty Sign -KeyUsage CertSign

• Export the Key run certmgr.msc
• Navigate to 'Certificates - Current User\Personal\Certificates', and right-click. Click All Tasks, and then click Export.
• Export format as Base-64 encoded X.509 (.CER)

Find your Root Cert and copy the {Thumbprint} $cert = Get-ChildItem -Path "Cert:\CurrentUser\My\{THUMBPRINT}"

New-SelfSignedCertificate -Type Custom -KeySpec Signature ` -Subject "CN=P2SChildCert" -KeyExportPolicy Exportable ` -HashAlgorithm sha256 -KeyLength 2048 ` -CertStoreLocation "Cert:\CurrentUser\My" ` -Signer $cert -TextExtension @("2.5.29.37={text}1.3.6.1.5.5.7.3.2")
