# Fake Certificate Authority for ACME testing
|
|
|
|
This will set up a test node running [pebble](https://github.com/letsencrypt/pebble)
|
|
to serve ACME certificate requests.

## "Snake oil" certs
|
|
|
|
The snake oil certs are hard coded into the repo for reasons explained [here](https://github.com/NixOS/nixpkgs/pull/91121#discussion_r505410235).
|
|
The root of the issue is that Nix will hash the derivation based on the arguments
|
|
to mkDerivation, not the output. [Minica](https://github.com/jsha/minica) will
|
|
always generate a random certificate even if the arguments are unchanged. As a
|
|
result, it's possible to end up in a situation where the cached and local
|
|
generated certs mismatch and cause issues with testing.
|
|
|
|
To generate new certificates, run the following commands:
|
|
|
|
```bash
|
|
nix-build generate-certs.nix
|
|
cp result/* .
|
|
rm result
|
|
```
