OpenKCM (Open Key Chain Manager) vs Oracle Cloud Infrastructure Secret Management

OpenKCM (Open Key Chain Manager) is a free, open-source key management service for governing encryption keys and protecting data at rest. It supports BYOK key import and HYOK, which keeps master keys in a customer’s infrastructure. Its recursive L1–L4 hierarchy makes data keys dependent on higher-level keys. Governance and policy control are handled by CMK, while Krypton performs cryptographic execution; applications request key operations through the KMIP API.

The Gateway is designed to run near applications, such as in Kubernetes or a cloud VPC, and the same software can operate across AWS, Azure and on-premise environments. Customer root keys can remain in AWS, Azure or GCP key services, or on-premise HSMs, while OpenKCM holds a reference to the L1 key. A kill switch can halt downstream key use by removing that reference or revoking the root key. CMK connects to a corporate identity provider and sends audit logs to SIEM systems. The project’s CMK and Krypton components are actively being developed; encryption and decryption operations are in progress, while audit export, high availability and disaster recovery are planned for 2027.

Oracle Cloud Infrastructure Secret Management stores, retrieves, rotates, and manages credentials used by applications and cloud environments. It supports database passwords, access tokens, third-party API keys, SSH private keys, application configuration secrets, and OAuth2 or JWT signing credentials. Administrators and applications can access secrets through APIs, SDKs, the CLI, and OCI Console. OCI Vault keys encrypt secrets, while OCI manages encryption, decryption, access control, and audit logging; OCI IAM policies provide granular permissions. Automatic rotation can run at intervals from one to 12 months and integrates with Autonomous AI Database and OCI Functions. Secrets can be replicated to as many as three destination regions, where replicas are read-only and inherit changes from the source. A tenancy can contain up to 5,000 secrets, with up to 30 active versions and 30 versions pending deletion per secret. The service is aimed at applications and cloud environments that need centrally managed secrets rather than credentials embedded in source code or configuration files. It is listed as free, though no price is provided.
