Implement http signatures support for the API #17565

42wim · 2021-11-06T00:26:33Z

This allows use to talk to the API with our ssh certificate (and/or ssh-agent) without needing to fetch an API key or tokens.
It will just automatically work when users have added their ssh principal in gitea.

This needs client code in tea
Update: also support normal pubkeys

I've made PRs against go-sdk and tea:

lunny · 2021-11-07T03:03:20Z

Did Git supports the standard?

42wim · 2021-11-07T09:36:32Z

Did Git supports the standard?

no

42wim · 2021-11-11T20:32:05Z

Is this something that could still get in 1.16 ?

I think we have feature freezed for v1.16 before this PR sent. I would like to put it into v1.17 .

I'm afraid this may result in a performance problem like we encountered in token ?

42wim · 2022-02-13T13:55:07Z

I'm afraid this may result in a performance problem like we encountered in token ?

Can you give some more context ?
If the signature header doesn't exist there is no performance impact on the API, no further checks or verification is done.

lunny · 2022-06-03T03:44:23Z

@42wim Good work for that. But just like @6543 said, I think tests are needed. I think it's not difficult to add some tests in integrations test.

42wim · 2022-06-03T22:34:49Z

@lunny remarks fixed and integration tests added

CI failure is related.

42wim · 2022-06-04T15:24:40Z

latest CI failure seems to be a CI issue

zeripath · 2022-06-04T16:00:21Z

I'm gonna ignore this CI failure pass but if we see it a few times in other PRs and this one again I think we need to go hunt if there is a potential deadlock...

Hmm... it also happened on

https://drone.gitea.io/go-gitea/gitea/55674/2/15 - here was in code.gitea.io/gitea/modules/markup.render
https://drone.gitea.io/go-gitea/gitea/55672/2/15 - here was in github.com/go-testfixtures/testfixtures/v3.(*mySQL).resetSequences

I guess I can still ignore...

lunny · 2022-06-04T16:15:48Z

But yesterday, it's right https://drone.gitea.io/go-gitea/gitea/55639 for the same PR

42wim · 2022-06-04T18:21:01Z

Failed again, but seems to happen in other recent drone builds too.
