Create self-signed certificates for local and private testing

This self-signed SSL certificate generator creates private keys and certificates for development, internal services, labs, and local HTTPS testing. You can adjust validity and certificate details for the environment you are simulating.

Use self-signed certificates for non-public testing only; public websites should use certificates from a trusted certificate authority.
