While refactoring an HTTP server, I noticed that the `verifyHmac` function was imported but never called

While refactoring an HTTP server, I noticed that the verifyHmac function was imported but never called. This indicates a leftover artifact from previous development, which can lead to confusion and potential maintenance issues. It's important to clean up unused code to keep the project organized and reduce unnecessary dependencies. The correct approach is to remove the import and any associated references to ensure the codebase remains lean and maintainable.
