About The Project

This web app makes use of cryptographic methods with the help of the OpenSSL command line program. For this purpose, the web app implements the functions from the command line program in two different ways: in a GUI and as a command line interface.

It brings the OpenSSL toolkit into the browser as WebAssembly bytecode. The new web standard WebAssembly serves as a compilation target for languages like C/C++ and allows client-side execution in the browser. Compared to an interpreted language such as JavaScript, WebAssembly bytecode benefits from, among other things, near-native execution speed.

Built With

• Emscripten
• React.js
• RxJs
• Bootstrap

Getting Started

Prerequisites

• Emscripten SDK (if using locally installed emsdk)

  # Activate PATH and other environment variables in the current terminal
  source /path/to/emsdk_env.sh

Installation

1. Clone the repository

   git clone https://github.com/janeumnn/openssl-webapp.git

2. Install NPM packages

   npm install

Usage

• Run the app in development mode

  npm start

• Build the app to the build folder. It bundles the app with an individual webpack config, so that it outputs only single files for the use in CrypTool Online.

  npm run build:cto-app

• Run build script in order to compile OpenSSL with Emscripten

  • With locally installed emsdk

    npm run build:openssl

  • With emscripten/emsdk docker image

    npm run build:openssl:docker
