If you’re deploying this script in an enterprise, here’s a robust template: If you’re deploying this script in an enterprise,

for /l %%i in (1,1,100) do ( keyfilegenerator.cmd --output "key_%%i.vck" --size 1024 --format raw ) Many on-premise software vendors use a keyfilegenerator.cmd on an internal activation server. The script generates a machine-specific keyfile based on a hardware ID hash, which customers drop into their installation directory. 3. Automated CI/CD Pipelines In DevOps, you might need ephemeral keyfiles for encryption between build stages. Calling keyfilegenerator.cmd from a Jenkins or GitHub Actions Windows runner ensures each build uses fresh, non-reused keys.
