Password Generator

Beginner-friendly

After attending a cybersecurity seminar, you learned about the risks of reusing the same or similar-looking passwords across multiple platforms. To address this issue, you decided that using a password generator would be the best solution. However, because you don't completely trust online password generators, you chose to create your own software.

Features​

After careful consideration and research you come up with a list of requirements for your application:

  • It should prompt the user whether or not he wants to include/exclude uppercase characters, lowercase characters, special characters and/or digits in his password.
  • It should prompt the user for the length of the password.
  • It should be equipped with basic error handling. What happens if the user does not input what was expected?

In this demo example, a Python application was run, but this project is programming language independent. Feel free to use whichever programming language you prefer.

Supporting Resources​

If you are experiencing some difficulties, don't worry. Take a peek into the supporting resources and reorganize your ideas, good luck!

Language-independent hints

  • Think about constructing a character set with all character groups selected by the user. For example, if the user only wants numbers and special characters your program would dynamically create a character set only with numbers and special characters.

  • Try to find a library of the programming language you are using that lets you generate random numbers. Then, based on that random number select a character from the character set. Do this as many times as the length requested by the user.

Python-specific hints/resources (including sample solution)

  • Take a look at the string page of Python's standard library. More specifically, at the String constants section.

  • Consider taking a look at the random page of Python's standard library, it contains various methods for generating random numbers and retrieving random values from strings/lists. In particular, consider the random.choices() method.

If you are experiencing some difficulties, consider taking a look at the sample solution.
