I am using openai api key, is there a way to restrict that key so that requests from only a particular IP is served, I have a backend in render.com, and I want to restrict that key to serve requests only from that backend server.
So that I don’t have to worry even if the key is leaked.
Is that option available in the dashboard, and if not, what are other ways to protect your key from being used despite it getting leaked.
Hey there!
So, you have a few different options for managing multiple API keys, and certain permissions for those keys. I’ve provided a screenshot below. You can reach this info at platform.openai.com
You could assign your backend a service account and use the api key specifically for that. If something happens, just reset the key.
In terms of “can I limit my key to specific IPs?” The short answer is no, although that’s not typically an API key’s job in the first place.
That’s not to say you can’t protect your key; quite the opposite. Things could get complicated quick though. I would consider looking up things like a Bastion network architecture, and see if that structure applies to your use case. Bringing up and reading about bastions should also get you thinking less about restricting key access, and more about restricting and tunneling traffic. I think that paradigm is closer to what you’re intending here.
If you can restrict your server’s traffic to one location, passing through one single port (the only open port in the machine), logging and tracing becomes relatively straightforward. If you begin to notice traffic is being sent to a different IP than the one you’re targeting, That’s when you know to cut off the machine because it could potentially be compromised.
Start getting comfy with things like iptables. The trick to all this isn’t about the keys themselves, but the connections passing the keys, and the ways in which you pass those keys.
It’s also possible to combine a setup like this with your own api keys for your own service. You would have to hard-code all of that yourself, and ensure both the server and client would only work when they give the handshake showing their keys.
This should give you more than enough to start with, and help you grasp 99.99% of all threat vulnerabilities.
welcome to the basics of cybersecurity and site reliability

Just be careful not to get too lost in the sauce; security is important, but it can quickly turn into a rabbit hole where you end up spending your entire time fortifying an empty system that doesn’t really need enterprise bank-grade security lol.
That is a feature that is available on Microsoft Azure
IP allowlist is a potential feature if having an Enterprise API account - a service level when your company is big enough that “OpenAI comes marketing to you”.
