Zenroom - crypto language VM
Zenroom is a brand new virtual machine for fast cryptographic operations on Elliptic Curves. The Zenroom VM has no external dependencies, includes a cutting edge selection of C99 libraries and builds a small executable ready to run on: desktop, embedded, mobile, cloud and browsers (webassembly). It also compiles unikernel (without Linux).
Zencode is the name of the language executed by Zenroom: it is simple to understand and can process large data structures while operating cryptographic transformations on them.
Zencode is a Domain Specific Language whose design is informed by pilot use-cases in the DECODE Project.

Latest stable release is 0.9:
- Javscript (nodeJS and WASM)
- Linux (ARM and x86)
- Windows (EXE and DLL)
- Apple (OSX and iOS)
- Source Code
- Git repository
- Releases archive
Zenroom is designed to be embedded inside host applications and used from its very simple interface to execute code on an input and return an output of the transformation. The embedding API is:
This API can be called in similar ways from a variety of languages and in particular four wrappers already facilitate its usage:
- Python language bindings
- Go language bindings
- Java (JNI) and SWIG (universal) bindings inside source
Zenroom is software in BETA stage and is part of the DECODE project about data commons and technological sovereignty. Our effort is that of improving people's awareness of how their data is processed by algorithms, as well facilitate the work of developers to create along privacy by design principles.
This software aims to make it easy and less error-prone to write portable scripts using end-to-end encryption inside isolated environments that can be easily made interoperable. Basic crypto functions provided include primitives to manage a/symmetric keys, key derivation, hashing and signing functionalities.
Zenroom is software inspired by the language-theoretical security research, it allows to expresses cryptographic operations in a readable scripting language that has no access to the calling process, underlying operating system or filesystem.
Zenroom's restricted execution environment is a sort of sandbox whose parser is based on LUA's syntax-direct translation and has coarse-grained control of computations and memory. The Zenroom VM is designed to "brittle" and exit execution returning a meaningful message on any error.
Zenroom's documentation and examples are being written to encourage a declarative approach to scripting, providing functional tools to manipulate efficiently even complex data structures.
The main use case for Zenroom is that of distributed computing of untrusted code where advanced cryptographic functions are required, for instance it can be used as a distributed ledger implementation (also known as blockchain smart contracts).
This project is receiving funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement nr. 732546 (DECODE).
