# Using a web server certificate Once you go to production – especially public production – you will need an 'official' certificate signed by an internal certificate authority (CA) or one of the global certificate authorities. If you have an internal certificate authority, and have the ability to request a certificate, follow these steps to [Request a web server certificate](/stifler/configuration/securing-stifler-operations-with-ssl/using-a-full-iis-certificate/requesting-a-web-server-certificate.md). Self-signed certificates are great for testing under SSL to make sure your application works, but they aren't practical for production apps as the certificate would have to be installed on every machine you'd expect to trust this certificate. If you must use a self-signed certificate, see [Using a self-signed certificate](/stifler/configuration/securing-stifler-operations-with-ssl/using-iis-to-create-a-self-signed-certificate.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
