Caesar Cipher

Hey everyone,

Today, I’m excited to introduce my latest creation for my computer science class – a Caesar Cipher Web Application. It’s a simple yet effective tool for anyone fascinated by the world of cryptography.

What’s the Caesar Cipher Web App?

The Caesar Cipher is a classic method of encryption that shifts the letters of the alphabet by a set value. My web app brings this ancient technique into the digital age, allowing users to easily encrypt or decrypt text.


  • Encryption and Decryption: Input text and apply the Caesar Cipher to encrypt or decrypt it.
  • Customizable Shift Value: Use a slider to select how many letters to shift.
  • Instant Results: See the encrypted or decrypted text immediately.
  • User-friendly Interface: Intuitive design for hassle-free usage.
  • Export Options: Save your results as a text file for later reference.

Getting Started:

  1. Clone the repository from GitHub.
  2. Open the folder and launch the web app in your browser.
  3. Start encrypting or decrypting text right away!

How to Use:

  1. Visit the Caesar Cipher Web App.
  2. Enter text for encryption or decryption.
  3. Adjust the shift value using the slider.
  4. Choose “Encrypt” or “Decrypt” to see the magic happen.
  5. Export your result as a text file if needed.

Join the Project:

I welcome contributions! If you’re interested in improving or adding new features to the app, here’s how you can get involved:

  1. Fork the GitHub repo.
  2. Create a new feature branch.
  3. Commit your enhancements.
  4. Push the branch and create a pull request.

I hope you find this tool both fun and educational. Cryptography has always been a fascinating area for me, and I’m glad to share this passion through my web app.

Happy encrypting!
