Node.js – diffieHellman.getGenerator() Method
The diffieHellman.getGenerator() method returns the Diffie-Hellman generator in the specified encoding. A string is returned in case an encoding is passed, else a buffer is returned.
Syntax
diffieHellman.getGenerator([encoding])
Parameters
encoding - This parameter specifies the encoding of the return value.
Example 1
Create a file with the name "generator.js" and copy the following code. After creating the file, use the command "node generator.js" to run this code as shown in the example below:
// diffieHellman.getPrime() Demo Example // Importing cryptoDiffieHellman from the crypto module const { createDiffieHellman } = require('crypto'); // Initializing the diffieHellman object const dh = createDiffieHellman(512); // Generate DiffieHellman's Generator // Defining generator let dhGenerator = dh.getGenerator() console.log('Buffer (when encoding is not specified) : ', dhGenerator) // Encoding specified // Return String dhGenerator = dh.getGenerator('base64') console.log('String (when encoding is specified) : ', dhGenerator)
Output
Buffer (when encoding is not specified) : <Buffer 02> String (when encoding is specified) : Ag==
Example 2
Let's take a look at one more example.
// diffieHellman.getGenerator() Demo Example // Importing cryptoDiffieHellman from the crypto module const { createDiffieHellman } = require('crypto'); // Generating keys for 'a' const a = createDiffieHellman(512); // Generating prime for 'a' const primeA = a.getPrime(); // Generating a's generator const generatorA = a.getGenerator() // Generating a's generatorKeys const keyA = a.generateKeys(); // Generating keys for b const b = createDiffieHellman( primeA, generatorA ); // Generating prime for b const primeB = b.getPrime(); // Generating b's generator const generatorB = b.getGenerator() // Generating b's generatorKeys const keyB = b.generateKeys(); // Exchanging the secret const secretA = a.computeSecret(keyB); const secretB = b.computeSecret(keyA); let isSymmetric = secretA.toString('hex') == secretB.toString('hex') console.log('Are keys Symmetric : ${ isSymmetric }')
Output
Are keys Symmetric : ${ isSymmetric }
