crypto.getCurves() Method in Node.js


The crypto.getCurves() method will return an array that contains names of all the supported elliptic curves. The crypto package has a huge list of elliptic curves that can be used for creating Elliptic Curve Diffie-Hellman (ECDH) key exchange object

Syntax

crypto.getCurves()

Parameters

Since it returns a list of all the elliptic curves. It does not need any arguments.

Example

Create a file with name – curves.js and copy the below code snippet. After creating file, use the following command to run this code as shown in the example below −

node curves.js

curves.js

 Live Demo

// A node demo program for getting all elliptic curves

// Importing the crypto module
const crypto = require('crypto');

// Calling the getCurves() method
const curves = crypto.getCurves();

// Printing the list of all the algorithms there is
console.log("The list of all elliptic curves are as follows: ", curves);

Output

C:\home
ode>> node curves.js The list of all elliptic curves are as follows: [ 'Oakley-EC2N-3', 'Oakley-EC2N-4', 'SM2', 'brainpoolP160r1', 'brainpoolP160t1', 'brainpoolP192r1', 'brainpoolP192t1', 'brainpoolP224r1', 'brainpoolP224t1', 'brainpoolP256r1', 'brainpoolP256t1', 'brainpoolP320r1', 'brainpoolP320t1', 'brainpoolP384r1', 'brainpoolP384t1', 'brainpoolP512r1', 'brainpoolP512t1', 'c2pnb163v1', 'c2pnb163v2', 'c2pnb163v3', 'c2pnb176v1', 'c2pnb208w1', 'c2pnb272w1', 'c2pnb304w1', 'c2pnb368w1', 'c2tnb191v1', 'c2tnb191v2', 'c2tnb191v3', 'c2tnb239v1', 'c2tnb239v2', 'c2tnb239v3', 'c2tnb359v1', 'c2tnb431r1', 'prime192v1', 'prime192v2', 'prime192v3', 'prime239v1', 'prime239v2', 'prime239v3', 'prime256v1', 'secp112r1', 'secp112r2', 'secp128r1', 'secp128r2', 'secp160k1', 'secp160r1', 'secp160r2', 'secp192k1', 'secp224k1', 'secp224r1', 'secp256k1', 'secp384r1', 'secp521r1', 'sect113r1', 'sect113r2', 'sect131r1', 'sect131r2', 'sect163k1', 'sect163r1', 'sect163r2', 'sect193r1', 'sect193r2', 'sect233k1', 'sect233r1', 'sect239k1', 'sect283k1', 'sect283r1', 'sect409k1', 'sect409r1', 'sect571k1', 'sect571r1', 'wap-wsg-idm-ecid-wtls1', 'wap-wsg-idm-ecid-wtls10', 'wap-wsg-idm-ecid-wtls11', 'wap-wsg-idm-ecid-wtls12', 'wap-wsg-idm-ecid-wtls3', 'wap-wsg-idm-ecid-wtls4', 'wap-wsg-idm-ecid-wtls5', 'wap-wsg-idm-ecid-wtls6', 'wap-wsg-idm-ecid-wtls7', 'wap-wsg-idm-ecid-wtls8', 'wap-wsg-idm-ecid-wtls9' ]
