SecureIT - Data Security using Cryptography and Steganography

Run in GitPod

This is a Python based tool to encrypt files and important data into a very secure form.
It uses Cryptography (RSA, AES and TripleDES) and Steganography (Image Steganography and Video Steganography)

Requirements (installable via pip)

What I used?

pycrypto - for Cryptography based encryption - It is used to encrypt and decrypt data into secured unreadable form.
opencv2 - for Steganography - It is used for image and video manipulation. We used it for embedding encrypted data into images/videos.
rsa - for RSA based encryption - RSA is a asymmetric encryption method, used for encrypting data.

How to run the program?

Download this GitHub repository
- Either Clone the repository
```
 git clone https://github.com/Kunal-Attri/Data-Security-using-Cryptography-and-Steganography.git
```
- Or download and extract the zip archive of the repository.
Download & Install requirements
- Ensure that you have Python 3 installed.
- Open terminal in the Repository folder on your local machine.
- Run the following command to install requirements.
```
 pip install -r requirements.txt
```
Run the Program
```
python main.py
```
Expected Interface:
Generate RSA Keys
- If running first time, you need to generate RSA Keys.
- Generate it using option no 5.
Ready to Secure data
- Now, you can secure your data files into either images or videos.
