# VaultSecret

Metadata for one stored secret. The secret value is never returned. `fingerprint` is a keyed SHA-256 digest of the value: equal fingerprints within one scope mean equal values, but a workspace secret and its intern copy carry different fingerprints. `hosts` and `fingerprint` are `null` only for legacy rows written before host binding was required; storing the secret again assigns hosts.

## Example Usage

```typescript theme={null}
import { VaultSecret } from "@openrouter/sdk/models";

let value: VaultSecret = {
  createdAt: new Date("2026-09-15T17:44:00.000Z"),
  fingerprint:
    "sha256:9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08",
  hosts: [
    "api.github.com",
  ],
  name: "github_token",
};
```
