Clortho Engine

The open-source licensing backend that powers Keyva.

Keyva is built on top of Clortho, a high-performance, open-source licensing engine written in Go. While Keyva provides a beautiful management dashboard and hosted service, Clortho handles the core logic of key generation, signing, and cryptographic validation.

Clortho is designed to be:

  • Fast: Built with Go for high-throughput validation.
  • Secure: Uses modern cryptography (Ed25519) for signing keys.
  • Portable: Can be run as a standalone single binary or container.

Open Source

We believe in transparency and community-driven development. The core engine is available on GitHub under the MIT license. You can inspect the code, contribute features, or even self-host it and build your own UI or reach out to us about self-hosted Clortho support in Keyva.
