Protect Your Google Cloud API Keys

Q: How do I protect my Google Cloud API key?

ShieldKey wraps your Google Cloud API key in a proxy token. Your real key stays encrypted — team members use revocable shield tokens that can be disabled in one click, without rotating the underlying key.

Q: Can I use ShieldKey with the google-auth-library SDK?

Yes. ShieldKey works as a drop-in proxy. Point your google-auth-library SDK at proxy.shieldkey.io and use a shield token instead of your real API key. No code changes beyond the base URL and key.

Q: What happens to my Google Cloud key if a team member leaves?

Revoke their shield token instantly from the ShieldKey dashboard. Your real Google Cloud key stays active — no rotation, no downtime, no re-deploying secrets across services.

Before & After

See how ShieldKey protects your Google Cloud integration with minimal code changes.

Before — raw Google Cloud key

import { GoogleAuth } from "google-auth-library";

const auth = new GoogleAuth({
  keyFile: "./service-account.json",  // ← sitting in repo
  scopes: ["https://www.googleapis.com/auth/cloud-platform"]
});

const client = await auth.getClient();
const res = await client.request({ url: "..." });

After — ShieldKey proxy token

// ShieldKey proxies the request — no service account file needed

const res = await fetch("https://proxy.shieldkey.io/gcp/...", {
  headers: {
    "Authorization": "Bearer sk_shield_t_2d7b...",  // ← revocable
    "X-Shield-Destination": "https://googleapis.com/..."
  }
});

What ShieldKey Does for Your Google Cloud Keys

Instant Revocation

Disable any team member's access to your Google Cloud key in one click. No key rotation. No downtime. No re-deploying environment variables.

Spend Limits

Set per-token spend caps so a compromised token can't run up your Google Cloud bill. Get alerts before limits are hit.

IP Allowlisting

Restrict each shield token to specific IPs or CIDR ranges. Even if a token leaks, it's useless from unauthorized networks.

Full Audit Trail

See every API call made through your Google Cloud key — who made it, when, from where, and what they accessed.

Zero-Knowledge Encryption

Your Google Cloud key is encrypted with AES-256-GCM. It's only decrypted in memory during request proxying — never stored in plaintext.

Team Access Control

Issue individual shield tokens to each team member. When someone leaves, revoke their token — everyone else keeps working.

FAQ

How do I protect my Google Cloud API key?

Add your Google Cloud key to ShieldKey's encrypted vault. ShieldKey generates a proxy token (starting with sk_shield_t_) that your team uses instead. Your real AIza key stays encrypted and is never exposed to team members.

Can I use ShieldKey with the google-auth-library SDK?

Yes. Point your google-auth-library SDK at proxy.shieldkey.io and use a shield token instead of your real API key. The SDK works identically — ShieldKey transparently proxies every request.

What happens to my Google Cloud key if a team member leaves?

Revoke their shield token from the dashboard. Your real Google Cloud key stays active — no rotation, no downtime, no re-deploying secrets across services. Everyone else keeps working without interruption.

Does ShieldKey add latency to Google Cloud API calls?

ShieldKey's proxy adds less than 25ms at the p50. The proxy decrypts your key in memory, forwards the request, and streams the response back. For most Google Cloud API calls, this overhead is negligible.
