C2PA Node.js library

The c2pa-node-v2 repository implements a Node.js API that can:

• Read and validate C2PA data from media files in supported formats.
• Add signed manifests to media files in supported formats.

WARNING: This is an early version of this library, and there may be bugs and unimplemented features.

Prerequisites

To use the C2PA Node library, you must install:

• A supported version of Node.
• Rust.

If you need to manage multiple versions of Node on your machine, use a tool such as nvm.

Installation

Installing for use in an app

Using npm:

$ npm install @contentauth/c2pa-node

Using Yarn:

$ yarn add @contentauth/c2pa-node

Using pnpm:

$ pnpm add @contentauth/c2pa-node

This command will download precompiled binaries for the following systems:

• Linux x86_64
• Linux aarch64 (ARM)
• macOS aarch64 (Apple Silicon)
• macOS x86_64 (Intel Mac)
• Windows x86
• Windows ARM

All other platforms require building a custom binary as described below, since the postinstall step builds the Rust library into a native Node.js module on your machine.
