Sign

Signs data specified KMS key.

TypeScript

import { cloudApi, serviceClients, Session } from "@yandex-cloud/nodejs-sdk";

const AsymmetricSignRequest =
  cloudApi.kms.asymmetricsignature_asymmetric_signature_crypto_service
    .AsymmetricSignRequest;

(async () => {
  const authToken = process.env["YC_OAUTH_TOKEN"];

    AsymmetricSignRequest.fromPartial({
      keyId: "keyId",
      message: Buffer.from([]),
    })
  );
  console.log(result);
})();

AsymmetricSignRequest

keyId : string

ID of the asymmetric KMS key to use for signature.

message : bytes

Message to sign. Should be encoded with base64.

AsymmetricSignResponse

keyId : string

ID of the asymmetric KMS key that was used for signature.

signature : bytes

Value of signature. Signature value is produced in accordance with RFC 8017 for RSA and is a DER-encoded object as defined by ANSI X9.62-2005 and RFC 3279 Section 2.2.3 for ECDSA.
