Zenroom crypto VM

Zenroom is a secure language interpreter of the domain-specific Zencode, making it easy to execute fast cryptographic operations on any data structure.

The Zenroom VM is very small, has no external dependency, is fully deterministic and is ready to run end-to-end encryption on any platform: desktop, embedded mobile, cloud micro-services, and web browsers. Zenroom works inside applications written in Javascript, Python3, Rust or Golang.

Zencode has a no-code approach. It is a domain-specific language (DSL) similar to human language. One can process large data structures through complex cryptographic and logical transformations.

Zencode helps developers to empower people who know what to do with data: one can write and review business logic and data-sensitive operations without learning to code.

This software has zero dependencies. If you chose to use it in your project be assured that we intend to support the same code to still run in 20 years from now on any target platform.

Applications

Many applications already include Zenroom and use the Zencode language.

Getting Started

To quickly try out Zenroom using the Zencode language with some examples navigate to ApiRoom and start typing into the browser.

The Zenroom VM runs locally in your browser (needs WASM) and ApiRoom provides various examples to show operational crypto flows.

ApiRoom is also an IDE (Integrated Development Environment) and by signing in with a username and password you can save your contracts and download them as a Dockerfile micro-service ready to deploy.
