Password Generator

Description

A web app to generate password(s) or passphrase(s) based on user preferences. The strength of the generated passwords is evaluated by calculating their entropy based on the formula $E = \log_2(C^L)$ [1].

• Front-end: Client side UI
• Back-end: Server side APIs have the format of /api/v1/character_type/password_length/amount_to_be_generated. Note that character_type and password_length are required, whereas amount_to_be_generated is optional and defaults to 1.
• Tech Stack: HTML, CSS, Bootstrap, JavaScript, Python, Flask

Demo

Local Installation & How to Use

One time set up for virtual environment:

$ python3.10 -m venv .venv
$ source .venv/bin/activate
$ python -m pip install -U pip
$ python -m pip install -r utilities/requirements.txt
$ deactivate

Start the server:

$ cd server
$ flask run

Start the client:

$ cd client
$ python -m http.server
