MysteryBox is now called SecretStash. The Nebius AI Cloud CLI, API and Terraform provider still use the mysterybox service identifier. Keep using mysterybox in scripts and manifests.
SecretStash enables you to store sensitive data in an encrypted form. For example, you can save API keys, tokens or certificates. After that, you can reuse them in your scripts, configuration files or applications, and thus avoid hardcoding sensitive data. The service is in preview, and available in all Nebius AI Cloud regions.
