I have created a login flow that authenticates a front end application (written in Vue.js) to retrieve the user_api_key of a Discourse user, following the guidelines written by @sam here . The authentification works, however the concern I have is with storing the private key safely. At the moment th…

As in an Electron/Tauri app? I have no idea what you would choose, I assume they have some mechanism for secure storage, maybe if you are lucky you can use keychain on mac and something similar on windows.

It’s a web application, hosted on a server. The concern is that somehow the payload could be intercepted if the private key is exposed. I’m aware this is a more general concern with javascript encryption, but asking in case there is a more secure practice for authenticating a web app from Discourse. …

The user api key system is not designed for this use case, if you go through the dance of generating a private key and then go ahead and store it on the server on behalf of the user, why bother with all this dancing, just generate the keys server side. Super hard for me to provide any guidance with…

It rather is a standalone web application that uses the Discourse API, so in a way Discourse is the server. …

I’m also curious about this, as I’ve started to use the software developed by @owengot . Based on what @tanius , do you think this is a safe way to do it @sam ?

[图片] tanius: Then he discovered the hack that the same private key can be used for multiple users, so he stored it in a file on the web host that also serves the other static files of the web application (JS, CSS etc.). That makes it fast … but now that private key is (1) a shared one and (2) st…

是的，千万不要这样做。私钥本应为每个客户端单独生成并保密。

生成密钥所需的 10 秒时间是必须付出的代价。不过，有一些 JavaScript 加密 API 可以加快这一过程。
