IBM Cloud Secrets Manager vs OpenBao

IBM Cloud Secrets Manager has no write-up on Specifiction yet; its figures are above.

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.
