Business Source License 1.1 Parameters Licensor: Shankar Kambam Licensed Work: certctl The Licensed Work is © 2026 Shankar Kambam. Additional Use Grant: You may make use of the Licensed Work, including in production for your internal business operations and for operations that provide products or services to your own customers, provided that you may not offer the Licensed Work as a Commercial Certificate Service. A "Commercial Certificate Service" is any product or service that provides third parties with access to or control of any substantial set of the certificate management functionality of the Licensed Work — including but not limited to lifecycle management, discovery, monitoring, alerting, renewal automation, deployment, revocation, certificate authority operation, certificate issuance, certificate signing, or any combination thereof — where compensation, in any form, is received in connection with such access or control. This restriction applies irrespective of whether such functionality is the principal, ancillary, supporting, or one of several values provided by the product or service, and irrespective of whether the Licensed Work is presented under its original name, a modified name, or no name at all. For the avoidance of doubt: (a) you may run the Licensed Work in production to manage certificates for products or services that you offer to your customers, where the principal value of those products or services is something other than the Licensed Work's certificate management functionality (for example, you operate a banking application and use the Licensed Work internally to manage TLS certificates for that application); (b) for the purposes of this Additional Use Grant, "third party" excludes (i) your employees, (ii) your contractors acting on your behalf, and (iii) your Affiliates. "Affiliate" means any entity that (1) directly or indirectly controls you, (2) is directly or indirectly controlled by you, or (3) is directly or indirectly under common control with you, where "control" means either (A) ownership of more than fifty percent (50%) of the voting interests of the entity, or (B) the power to direct the management and policies of the entity, whether through voting securities, contract, or otherwise; (c) the restriction on offering a Commercial Certificate Service applies regardless of whether the Licensed Work is hosted, managed, embedded, bundled, or integrated with another product or service.

This covenant terminates with respect to any person who initiates a patent infringement action against the Licensor or against any contributor to the Licensed Work. Termination and reinstatement.

Your rights are reinstated automatically if you cease the violation and provide written notice to the Licensor at the contact address above within thirty (30) days of becoming aware of the violation. If you violate this License a second time after such reinstatement, your rights are not subject to further reinstatement. Contributions. The Licensor does not accept third-party contributions to the Licensed Work. Any code, documentation, or other material submitted to the Licensor or to any repository hosting the Licensed Work is provided at the submitter's sole risk, confers no rights or obligations on the Licensor, and is not incorporated into the Licensed Work. Trademark and naming. This License does not grant you any right in any trademark, service mark, trade name, or logo of the Licensor or its Affiliates. Forks, derivative works, and modifications of the Licensed Work must not use the name "certctl," any name confusingly similar to "certctl," or any Licensor trademark in their distributed form, marketing materials, package metadata, or service offerings.

Severability. If any provision of this License is held to be invalid, illegal, or unenforceable in any jurisdiction, that holding does not affect the validity, legality, or enforceability of any other provision of this License, which remains in full force and effect. Survival. The disclaimers of warranty, the patent non-assertion provisions (with respect to acts occurring before termination), the governing-law and venue provisions, and this survival provision survive any termination of this License.
