Introduction

VirgilCrypto is a stack of security libraries (ECIES with Crypto Agility wrapped in Virgil Cryptogram) and an
open-source high-level cryptographic library that allows you to
perform all necessary operations for securely storing and transferring data in your digital solutions. Crypto Library
is written in C++ and is suitable for mobile and server platforms.

Virgil Security, Inc., guides software developers into the forthcoming security world in which everything will be
encrypted (and passwords will be eliminated). In this world, the days of developers having to raise millions of
dollars to build a secure chat, secure email, secure file-sharing, or a secure anything have come to an end. Now
developers can instead focus on building features that give them a competitive market advantage while end-users can
enjoy the privacy and security they increasingly demand.

Library purposes

• Asymmetric Key Generation
• Encryption/Decryption of data
• Generation/Verification of digital signatures

Getting started

First, you need to install the package from npm:

npm install virgil-crypto

If you are not using npm, follow our UMD guide to get started.

Second, you need to decide which approach to use in your application. We provide 2 options here:

• WebAssembly. This is our recommended approach. List of supported browsers.
• asm.js. Use it only in case you need to support old web browsers.

Third, you will need to setup you development environment (skip this step if you are using Node.js):

• Webpack
• Create React App
• React Native

Not found your environment? Create an issue on GitHub and we will try our best to help you. Make sure to describe your environment as much as possible.

Last, you need to get familiar with usage examples of the library.
