OpenBao vs Oracle Cloud Infrastructure Secret Management

OpenBao is a free, open-source system for storing and controlling access to secrets such as API tokens, encryption keys, passwords, and certificates. Management is available through a web UI, CLI, or HTTP API. Key/value secrets are encrypted before persistent storage, while dynamic credentials can be generated for Kubernetes and SQL databases and revoked when leases expire. Leases can be renewed, and individual secrets or groups can be revoked. OpenBao also encrypts and decrypts data without retaining it. Authentication methods include GitHub, LDAP, and AppRole, with token-based policies. Its storage barrier uses AES-256-GCM and verifies authentication tags during decryption. High-availability configurations are supported. Deployment options include packages, containers, binaries, source builds, and Helm; documentation covers Linux, macOS, FreeBSD, and Windows. Releases provide GPG signatures and SBOMs. Integrated Storage defaults to a 1 MiB maximum entry size, configurable with max_entry_size.

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.
