W3C Web Cryptography API (@trust/webcrypto)
W3C Web Cryptography API for Node.js
W3C's Web Cryptography API defines a standard interface for performing cryptographic operations in JavaScript, such as key generation, hashing, signing, and encryption. This package implements the API for Node.js, in order to support universal crypto-dependent code required by protocols such as JOSE and OpenID Connect.
Table of Contents
Security
TBD
Background
The purpose of this package is to enable development of universal JavaScript libraries that depend on the availability of cryptographic primitives in order to implement cryptographic protocols. The long term goal of the project is to encourage or provide a native, if not core Web Cryptography module.
Install
@trust/webcrypto requires recent versions of node and npm to run. For key generation operations, it also requires OpenSSL to be installed on the system.
$ npm install @trust/webcrypto --save
Not for use in Webpack
This library is not for use in Webpack.
The whole point of this library is that it's an exact duplicate of the browser's WebCrypto API, for the server side.
For Webpacked web applications,
you don't need it (and can't use it).
If this module is transitively included by another dependency,
you have to exclude it by adding it to the externals section in the Webpack config,
such as this:
externals: {
'@trust/webcrypto': 'crypto'
}
Usage
const crypto = require('@trust/webcrypto')
Develop
Install
$ git clone [email protected]:anvilresearch/webcrypto.git
$ cd webcrypto
$ npm install
Test
$ npm test
