| 13 | * Runtime binding for `kms:GenerateMac`. |
| 14 | * |
| 15 | * Bind this operation to an HMAC KMS {@link Key} (or the `alias/...` name of |
| 16 | * a pre-existing key) to get a callable that automatically injects the |
| 17 | * `KeyId`. Computes an HMAC inside KMS — the MAC key never leaves the HSM, |
| 18 | * so any party with `kms:VerifyMac` can validate tokens without ever |
| 19 | * holding the shared secret. |
| 20 | * |
| 21 | * ### Message Authentication |
| 22 | * **Example:** Compute an HMAC |
| 23 | * ```typescript |
| 24 | * const generateMac = yield* AWS.KMS.GenerateMac(hmacKey); |
| 25 | * |
| 26 | * const { Mac } = yield* generateMac({ |
| 27 | * Message: new TextEncoder().encode("session-token-payload"), |
| 28 | * MacAlgorithm: "HMAC_SHA_256", |
| 29 | * }); |
