Node.js crypto.getHashes() Method

The crypto.getHashes() method is an inbuilt application programming interface of crypto module which is used to display the names of all the supported hash algorithms in an array.

Syntax:

crypto.getHashes()

Parameters: This method doesn’t accept any parameters.

Return Value: It returns the name of all the supported hash algorithms.

Below example illustrate the use of crypto.getHashes() method in Node.js:

Example:

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

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

// Calling getHashes method
const hash = crypto.getHashes();

// Prints all the supported hash algorithms
console.log("The list of all the hash "
        + "algorithms are : ", hash);

Output:

The list of all the hash algorithms are :  [ 'RSA-MD4',
  'RSA-MD5',
