They contain the following requirement:\n\n\u003e The CA SHALL host test Web pages that allow Application Software Suppliers to\n\u003e test their software with Subscriber Certificates that chain up to each\n\u003e publicly trusted Root Certificate. At a minimum, the CA SHALL host separate\n\u003e Web pages using Subscriber Certificates that are valid, revoked, and expired.\n \nIt uses the ACME protocol to obtain certificates. It serves a simple website\nwith some information explaining what the test site is for.\n\n\nFrom the CA/Browser Forum TLS Baseline Requirements: \n\nWhile this was built for Let's Encrypt, it should be usable by other ACME CAs.\n\n## Running test-certs-site\n\nThis is a standalone Go program. Once a 1.0 release is available, we will begin\npublishing releases.\n\n```shell\ngo run ./cmd/ -config config/test.json\n```\n\n## Avoiding Incidents\n\nThis software was inspired by several incidents we observed from other CAs, as\nwell as the complexity of our existing solution using off-the-shelf tools.\n\nSome categories of incidents we've observed include:\n \n* Allowing certificates to expire incorrectly, for the valid and revoked .\n* Serving unrevoked certificates on the revoked demonstration sites.\n\nA server with ACME integration is the most reliable way to ensure certificates\nare kept up-to-date, but the unusual requirements of serving revoked and expired\ncertificates is not a typical feature of other systems. Monitoring systems also\ndon't typically support ensuring that certificates are revoked or expired.\n\n## ACME challenges\n\nCurrently, test-certs-site only supports the TLS-ALPN-01 validation method.\nTo fulfil this challenge, and to serve the test sites, this program listens\non a configurable port, which should be exposed as the TLS port, :443.\n\nNote that in the test configuration listens on :5001 by default, which matches\n[Pebble's](https://github.com/letsencrypt/pebble) default validation port. \n\n## Key and Certificate Storage\n\nCurrently, test-certs-site stores all key material as paths on disk.\nTo ease running cert-test-program in cloud or ephemeral environments, we will\nwant to support some mechanism for persisting keys to secrets management.\n\nOther than the key and certificate storage, this program is stateless.\n\n## Observability\n\nThere is a configurable debug listener which exposes /debug/pprof and /metrics.\nLogs are printed in JSON to stderr.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fletsencrypt%2Ftest-certs-site","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fletsencrypt%2Ftest-certs-site","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fletsencrypt%2Ftest-certs-site/lists"}
