Password Generator.

npm i bruteforce-password-generator

• Import PasswordGenerator Class.

• Instantiate PasswordGenerator class.

• Use .nextPassword method on the Instantiated Class Variable to obtain:

  • Each time an unique password.

• Use .hasNextPassword method on the Instantiated Class Variable to obtain:

  • If or not ".nextPassword" has a next one in store.

• Example:

  import {
    PasswordGenerator,
    azAZ09_Combination,
  } from "bruteforce-password-generator";
  
  const passwordLength = 10;
  
  const passwordGenerator = new PasswordGenerator(
    azAZ09_Combination,
    passwordLength
  );
  
  const generatedPassword = passwordGenerator.nextPassword;
  
  console.log(generatedPassword);
  console.log(passwordGenerator.hasNextPassword);

  • This class remembers previously generated combinations and returns each time a new one of the requested length.
  • As the JavaScript heapspace is 4GB by default. Your application will encounter an "FATAL ERROR: Reached heap limit. Allocation failed - JavaScript heap out of memory." bottleneck.
  • I haven't added a clear method for the previously remembered combinations as this was not the purpose of this package.
  • I suggest you to enlarge the heap allocation or reinstantiate the class itself.

  How to enlarge the heap space:

  • Use the --max-old-space-size flag when running a Node. js application to increase the available memory heap.

  NODE_OPTIONS=--max-old-space-size=8192 npm start

  • Note that the flag needs to come before calling the file with the node command.

Tip:

• Use worker threads on the .nextPassword getter to increase the output speed.
