Once we get the SSH public key, I have to create linux VM with this SSH public key(Ready this script from myend without add SSH key).

Answer 1

Based on my understanding, your certificate should be DER encoded X.509 certificate with .cer extension.

You can get the public key from your certificate using the PowerShell script below:

$certPath = "testcert.cer"
$x509Cert = [System.Security.Cryptography.X509Certificates.X509Certificate2]::CreateFromCertFile($certPath)
$pk = $x509Cert.GetPublicKeyString()

Hope this helps!
