Vault is a secure storage for your organization's identities.
All identity key material in the vault is split into data chunks. Each chunk is AES-256 encrypted with a unique key.
The unique keys protecting the chunks are also AES-256 encrypted with key encryption keys.
The key encryption keys are stored in a key management service—a service built specifically for storing keys. No keys can be exported from the key management service—all encryption and decryption is done in the service.
