What's a good way to document Hydra configs?

Asked 2021-Jun-11 at 16:50

In argparse you provide help alongside the definition of the argument. This helps keep the doc up-to-date with the args.

Is there an option to do something similar in Hydra? Or some other preferred way for documenting the options, without having to list them manually within the hydra/help message?

Edit: this becomes an even greater problem when using call/instantiate and the config options depend on the code.

Music Bot discord.js issue, Cannot read property 'voice' of undefined

I'm trying to create a hydra-style bot discord with an embed that automatically gets assigned control reactions with which I can pause, resume, stop the music etc ...

I have a problem, if I try to start the command to pause typing '*psres' everything works fine, however, if I try to start the pause command via the reaction it gives me the following error:

ANSWER

Answered 2021-Apr-17 at 03:55

In your setup.js file the command handler is client.commands.get('psres').execute(message, client, args) with message, client and args as parameters. But in the pause/resume command file, you are executing execute (client, message, args) with client, message and args as param. The objects are not what you think it is because if you compare both of them, the parameters are not matching/placed in wrong order. So matching the parameters either according to the setup commands param or the way you are executing in the pause/resume command.

You are missing windres, so you need the package that contains it.

Is your question related to this feature request and in particular to this comment?

FYI: In Hydra 1.1, instantiate fully supports positional arguments so I think you should be able to call functools.partial directly without redefining it.

QUESTION

Centralized identity management with different providers

Asked 2021-Apr-22 at 15:06

I am going to build a web application that allows users to sign in with their Google or Twitter account. I think OpenID Connect(OAuth2) is the standard today to verify the identity. I also want to provide several API services that can be only accessed with a valid access token from either Google or Twitter.

For example, all the four API's above are going to be public and so I have to protect from unauthorized users. For NodeJS based API services I can use http://www.passportjs.org/ to protect all APIs.

Assume, in the future the number of API's will be grow for example up to 20 API's and sign in with Facebook account will be also allowed. Again, all the API's have to be protected and I have to do it 16 times with http://www.passportjs.org/. In addition add the new provider Facebook, I have to do the changes on all 20 APIs.

The question is, is their a way to keep centralized, which means in the future when I will provide more the providers for example GITHUB for sign in I would like to do changes in one place not in 20 places. Is the tool https://www.ory.sh/hydra what I need?

...

ANSWER

Answered 2021-Apr-22 at 15:06

These are perhaps the two primary features of OAuth 2.0 and Open ID Connect:

Federated sign in to your UIs via multiple identity providers and the ability to easily add new options such as GitHub in a centralised manner
Full control over claims included in access tokens, so that your APIs can authorize requests however you'd like

FOREIGN ACCESS TOKENS

You should aim to avoid ever using these in your apps. Your UIs and APIs should only use tokens issued by your own Authorization Server (Ory Hydra), which manages the connection to the Identity Provider. Adding a new sign in method will then just involve centralised configuration changes, with zero code changes in either UIs or APIs.

IF YOU DON'T HAVE AN AUTHORIZATION SERVER YET

Maybe have a look at the Curity Identity Server and its free community edition - use sign in with GitHub, which has strong support for both of these areas:

EXTERNAL RESOURCES

One exception to the above is that your APIs may occasionally need to access a user's Google resources after login, by calling Google APIs. This would require the token issued by Google. It can be managed via an embedded token approach - though it doesn't sounds like you need that right now.

Vulnerabilities

CVE-2020-5300 MEDIUM

In Hydra (an OAuth2 Server and OpenID Certified™ OpenID Connect Provider written in Go), before version 1.4.0+oryOS.17, when using client authentication method 'private_key_jwt' [1], OpenId specification says the following about assertion `jti`: "A unique identifier for the token, which can be used to prevent reuse of the token. These tokens MUST only be used once, unless conditions for reuse were negotiated between the parties". Hydra does not check the uniqueness of this `jti` value. Exploiting this vulnerability is somewhat difficult because: - TLS protects against MITM which makes it difficult to intercept valid tokens for replay attacks - The expiry time of the JWT gives only a short window of opportunity where it could be replayed This has been patched in version v1.4.0+oryOS.17

CVE-2019-17502 HIGH

Hydra through 0.1.8 has a NULL pointer dereference and daemon crash when processing POST requests that lack a Content-Length header. read.c, request.c, and util.c contribute to this. The process_header_end() function calls boa_atoi(), which ultimately calls atoi() on a NULL pointer.
