Key Management Service (KMS) is a Nebius AI Cloud service that enables you to issue and store cryptographic keys, so you can protect and secure your applications. By using KMS symmetric and asymmetric keys, you can encrypt and decrypt data, sign hashes or apply envelope encryption. The service is in preview, and available in all Nebius AI Cloud regions.
