Every other SDK already requires this key for record creation. This change makes Ruby consistent with the other SDKs. The SDK sets this key only during binding. An already-bound configuration cannot get this key later. Re-bind with a fresh one-time token, or set the `KSM_APPOWNERPUBLICKEY` environment variable if you use the read-only `EnvironmentStorage`. ### Security * **KSM-1193:** Resolved an encryption issue with `create_secret` commands, affected by versions 17.0.3, 17.0.4, 17.1.0, and 17.2.0. This fix affects only records created after the SDK upgrade. To fix any existing records, the records must be deleted and re-created. ### **Resources** * [RubyGems package](https://rubygems.org/gems/keeper_secrets_manager/versions/17.2.1) * [Ruby SDK Documentation](https://app.gitbook.com/s/-MJXOXEifAmpyvNVL1to/secrets-manager/developer-sdk-library/ruby-sdk) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.keeper.io/release-notes/enterprise/keeper-secrets-manager/2026/ruby-sdk-17.2.1.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
