​
Installation

Get Algoritmos de Encriptamiento running on your local machine in just a few steps.

​
Prerequisites

Before you begin, ensure you have the following installed:
  • Python 3.6 or higher (Python 3.13 recommended)
  • Git for cloning the repository
  • pip (usually comes with Python)
You can check your Python version by running python --version in your terminal.

​
Installation steps

1

Clone the repository

Clone the project repository to your local machine:
git clone https://github.com/RennfahrerU/Algoritmos-de-Encriptamiento.git
cd Algoritmos-de-Encriptamiento
2

Install pipenv

Install pipenv to manage the project dependencies:
pip install pipenv
Pipenv creates isolated virtual environments and manages package versions automatically.
3

Install dependencies

Use pipenv to install the required packages:
pipenv install
This command reads the Pipfile and installs Flask and other dependencies in a virtual environment.
[packages]
flask = "*"

[requires]
python_version = "3.13"
4

Verify installation

Verify that everything is installed correctly by checking the pipenv environment:
pipenv --venv
This should print the path to your virtual environment.

​
Project structure

Once installed, you’ll find the following structure: 
Algoritmos-de-Encriptamiento/
├── app.py              # Flask web application
├── main.py             # CLI version
├── sustitucion.py      # Caesar cipher implementation
├── transposicion.py    # Transposition cipher implementation
├── RSA.py              # RSA encryption implementation
├── util.py             # Utility functions
├── static/             # CSS and web resources
├── templates/          # HTML templates for web interface
├── Pipfile             # Dependencies
└── Pipfile.lock        # Locked dependency versions

​
Running the application

You can run the application in two ways:

​
Web interface

pipenv run python app.py
Once running, open your browser and navigate to http://localhost:5000.

​
Command-line interface

pipenv run python main.py
The CLI will prompt you for a message and automatically apply all three encryption algorithms.
The web interface runs on Flask’s development server. It’s perfect for learning but not suitable for production deployment.

​
Troubleshooting

​
Python version mismatch

If you encounter a Python version error, you can modify the Pipfile to match your installed Python version:
Pipfile
[requires]
python_version = "3.11"  # Change to your version
Then run pipenv install again.

​
Port already in use

If port 5000 is already in use, you can modify app.py to use a different port:
app.py
if __name__ == '__main__':
    app.run(debug=True, port=5001)  # Change port here

Now that you have everything installed, head over to the quick start guide to encrypt your first message!
