I lost access to a SealedSecrets key once , not because I deleted it, but because I didn't know where it was stored. The cluster kept running, the apps kept deploying, but the moment I tried to rotate the key or redeploy a sealed secret, I hit a wall. The controller couldn't decrypt anything. The only way out was to find the original key, and I had to dig through old manifests and cluster logs to get it back. That’s when I learned the hard way: SealedSecrets keys aren’t magical. They’re just Kubernetes secrets, and they can be lost if you don’t back them up. The SealedSecrets controller uses a single key to encrypt and decrypt secrets. If that key is lost, all your sealed secrets become unusable. You can’t just regenerate it , the encryption is tied to that specific key. The key is stored as a Kubernetes secret in the sealed-secrets namespace. If you don’t back it up, and it gets deleted or corrupted, you're out of luck. Here’s the command I use to back it up.…
