| 10 | * Runtime binding for `kms:Verify`. |
| 11 | * |
| 12 | * Bind this operation to an asymmetric SIGN_VERIFY KMS {@link Key} (or the |
| 13 | * `alias/...` name of a pre-existing key) to get a callable that |
| 14 | * automatically injects the `KeyId`. Verifying inside KMS (rather than with |
| 15 | * a downloaded public key) means the result is authorized and auditable by |
| 16 | * IAM/CloudTrail. |
| 17 | * |
| 18 | * A mismatched signature surfaces as the typed |
| 19 | * `KMSInvalidSignatureException` — a valid signature returns |
| 20 | * `SignatureValid: true`. |
| 21 | * |
| 22 | * ### Signing |
| 23 | * **Example:** Verify a Signature |
| 24 | * ```typescript |
| 25 | * const verify = yield* AWS.KMS.Verify(signingKey); |
| 26 | * |
| 27 | * const { SignatureValid } = yield* verify({ |
| 28 | * Message: new TextEncoder().encode("release-manifest-v1"), |
| 29 | * Signature: signature, |
| 30 | * SigningAlgorithm: "ECDSA_SHA_256", |
| 31 | * }); |
| 32 | * ``` |
| 33 | * |
| 34 | * **Example:** Treat a Bad Signature as a Value |
| 35 | * ```typescript |
| 36 | * const valid = yield* verify({ Message, Signature, SigningAlgorithm }).pipe( |
| 37 | * Effect.map(() => true), |
| 38 | * Effect.catchTag("KMSInvalidSignatureException", () => |
| 39 | * Effect.succeed(false), |
| 40 | * ), |
| 41 | * ); |
| 42 | * ``` |
