If you are self signing your certificates, I believe that the Common Name (CN) is what’s used for Vendor Name there in the Ignition gateway in 8.3

> 
> Write-Host "Setting up keystore directory..."
> # Create keystore directory if it doesn't exist
> if (-not (Test-Path -Path $keystoreDir)) {
> New-Item -ItemType Directory -Path $keystoreDir | Out-Null
> Write-Host "C:\Code\keystore directory created."
> }
> 
> # Change to keystore directory
> Set-Location $keystoreDir
> 
> Write-Host "Generating self-signed certificate..."
> # Generate keystore with self-signed certificate
> keytool -genkeypair -alias myalias1 -keyalg RSA -keysize 2048 -validity 3650 -keystore mykeystore1.jks -storepass PASSWORD -keypass PASSWORD -dname "CN=Amentum, OU=Advanced Solutions, O=Amentum, L=Tullahoma, S=TN, C=US"
> 
> # Export certificate chain to PKCS#7 (.p7b)
> Write-Host "Exporting certificate to .p7b format..."
> keytool -exportcert -rfc -alias myalias1 -keystore mykeystore1.jks -storepass PASSWORD -file myalias1.p7b
> Write-Host "Certificate exported successfully to myalias1.p7b"
> } catch {
> Write-Host "Failed to generate or export certificate. Error: $_"
> }
>
