It would be ideal to generate the test certificates dynamically by running this script prior to executing other tasks, rather than committing them to version control. This could also be implemented in Go and we have in Flipt repo similar code. The fixture certificates are valid for one year, after which the tests will start failing unless they are renewed.

i bumped them to expire in 10 years. id rather not introduce more potential for flakey tests by generating the certs on each run tbh
