License snapshot: Sekura JS Proprietary Software License, copyright © 2026 Jupiter Soft.
Sekura JS (sekura-js, sekura-sjv, and the sekura-sjs Visual Studio Code extension) is proprietary software. This page is a short guide; it does not replace or change the full license.
Using and redistributing binaries
A person or organization that lawfully obtains a compiled Sekura JS distribution may install and use it for lawful purposes under the license. Unmodified binary copies may be redistributed if the full license and applicable notices are kept with them and the redistribution does not imply that the distributor is affiliated with, endorsed by, or acting for Jupiter Soft.
Modification of Sekura JS binaries and source code is not granted by this license. Source code is not licensed for copying, modification, publication, or distribution unless Jupiter Soft expressly provides a separate written license or agreement. The full license also describes verification of binary authenticity, reverse-engineering restrictions subject to applicable law, warranty disclaimers, and liability limits.

Third-party components
Third-party libraries and tools remain governed by their own license terms; the Sekura JS proprietary license does not replace those terms. The source distribution records ZLIB, libsodium, Z3, optional CVC5, and VS Code extension development/test components separately in Third-Party Notices. The exact components and notices in a binary package may depend on how that package is built and distributed. Redistributors must preserve the applicable notices for components they include.
User-created SJP artifacts
An SJP does not become Jupiter Soft’s property or proprietary Sekura JS software merely because Sekura JS tools created, signed, processed, or verified it. The full license does not claim ownership of user-created SJP artifacts. Rights in a particular artifact depend on the applicable agreements and relationships among its creator, user, customer, employer, and other rights holders.
