Node.js crypto.createVerify() Method

crypto.createVerify( algorithm, options )

• algorithm: It is a string type value. A Sign instance can be created by applying the name of a signature algorithms, like 'RSA-SHA256', in place of a digest algorithms.
• options: It is an optional parameter that is used to control stream behavior. It returns an object.

// Node.js program to demonstrate the 
// crypto.createVerify() method

// Including crypto module
const crypto = require('crypto');

// Creating verify object with its algo
const verify = crypto.createVerify('SHA256');

// Returns the 'Verify' object
console.log(verify);
