May 01, 2020 · Using the Web Crypto API in Node.js A small number of third-party implementations of the Web Cryptography API for Node.js exists, and the Node.js team is in the process of assessing the potential of the Web Crypto API for Node.js applications, including a prototype implementation written in JavaScript. Sep 12, 2015 · Since WebCrypto API is already widely adopted by browsers, there is zero chance of going in the opposite direction and pushing Node's native crypto interface into that world.

Crypto has a method called createHash which allows you to calculate a hash. Its only argument is a string representing the hash.

Some algorithms need extra parameters: in these cases the algorithm argument is a dictionary object that includes the extra parameters. The Crypto module was added to Node.js before there was the concept of a unified Stream API, and before there were Buffer objects for handling binary data. As such, the many of the crypto defined classes have methods not typically found on other Node.js classes that implement the streams API (e.g. update() , final() , or digest() ).
