Service Overview
Secrets Manager is a service that encrypts customers’ sensitive information as Secrets (secure data) and stores and manages it safely. Remove hard-coded sensitive information from the application source code and retrieve it by invoking Secrets stored securely in a Key-Value format. A secret is encrypted with a user‑managed key in conjunction with the Key Management Service and stored securely.

Provided features
Secrets Manager provides the following features.
- Secret creation/deletion: Secrets Manager can create, delete, and manage Secrets. * The user stores security (sensitive) information in key/value format in the generated Secret.
- Secret lookup: You can retrieve Secret values based on custom policies and permission settings.
- Label-based version control: When a Secret is modified, you can set a label on the version, which is a snapshot of the uniquely generated data, allowing you to manage Secrets more efficiently.
Component
Secret
It stores sensitive (critical) information as a logical unit, encrypting security information values in Key/Value format with a KMS key.
- A Secret is an object created through the creation of a Secrets Manager product service in the Samsung Cloud Platform Console.
Version
It is a snapshot of unique data that is newly created each time a Secret is modified (the unit that stores the actual value of the Secret).
Label
It is a label or tag attached to a specific version of a Secret (a pointer for referencing a specific version).
Constraints
The limitations of the Secrets Manager service are as follows. Before use, be sure to review the following constraints and incorporate them into your service usage plan.
- Secrets Manager is a regional service, and a created secret can be used only within that region.
- When rotating a customer-managed key, the key version is changed internally. * By using the newly generated version of the key, you can decrypt data that was encrypted with the previous version of the key. * (maintain compatibility)
- Versions through key rotation are compatible up to the 100th version, regardless of the encryption algorithm.
