Add signature validation into the SDK

[soranoo]

Is your feature request related to a problem? Please describe.
Currently, to verify an outpost request, a manual implementation of the validation helper method is needed. (I didn't find a related method in the SDK codebase so far.) Which may lead to validation outdated or incorrect manual implementation.

Additional context

I am facing a problem that the request sign is always different from the sign created in my server (my validation method is based on the https://github.com/hookdeck/outpost/blob/main/examples/demos/nodejs/src/verify-signature.ts demo). I have no idea why the result is different while they are sharing the same AES key (they used to the same). If an official helper method is available, maybe I will be able to debug it more efficiently.

Thank you for your considerations

Hi there, thanks for the suggestion, I think it does make sense for us to include signature verification in the SDK. The SDKs are currently autogenerated by SpeakEasy, so we'll need to look into how we can extend it with custom logic.

In the meantime, if you require further assistance with the signature verification, feel free to create a Discussion or reach out on Slack and I'd be happy to help investigate the issue.
