I guess today is PowerShell day. I needed to create a quick self signed certificate on a Windows Server and didn’t care to go through the normal process. Here’s the snippets you need.
New-SelfSignedCertificate -DnsName server.domain.tld -CertStoreLocation cert:\LocalMachine\My
This command will spit out the Thumbprint of that certificate which we will need in the next command. Note, that this is a 1 year certificate.
Now let’s export the certificate.
$CertPassword = ConvertTo-SecureString -String “SomeStrongPassword” -Force –AsPlainText
Export-PfxCertificate -Cert cert:\LocalMachine\My\3579B7928D895B21CAECfe2F6BE1A6BCCA92C31 -FilePath C:\server.domain.tld.pfx -Password $CertPassword
Then we just need to export the public key.
Export-Certificate -Cert Cert:\LocalMachine\My\3579B7928D895B21CAECfe2F6BE1A6BCCA92C31-FilePath C:\server.domain.tld.cer
