Node.js | crypto.getCurves() Method
  • Last Updated : 16 Mar, 2020

The crypto.getCurves() method is an inbuilt application programming interface of the crypto module which is used to display an array with the names of all the supported elliptic curves.

Syntax:

crypto.getCurves()

Parameters: This method doesn’t accept any parameters.

Return Value: This method returns the name of all the supported elliptic curves.

Below example illustrates the use of crypto.getCurves() method in Node.js:



Example:




// Node.js program to demonstrate the 
// crypto.getCurves() method
  
// Including crypto module
const crypto = require('crypto');
  
// Calling getCurves method
const curve = crypto.getCurves();
  
// Prints all the supported elliptic curves
console.log("The list of all the elliptic curves are : ", curve);

Output:

The list of all the elliptic curves are :  [ 'Oakley-EC2N-3',
