- Load the file on the server.
- Dividing the uploaded file into N parts.
- Encrypting all the parts of the file using any one of the selected algorithms (Algorithm is changed with every part in round robin fashion).
- The keys for cryptography algorithms is then secured using a different algorithm and the key for this algorithm is provided to the user as public key.
After the above 4 steps you will have a N files which are in encrypted form which are stored on the server and a key which is downloaded as public key for decrypting the file and downloading it.
To restore the file, follow the following steps:
- Load the key on the server.
- Decrypt the keys of the algorithms.
- Decrypt all the N parts of the file using the same algorithms which were used to encrypt them.
- Combine all the N parts to form the original file and provide it to the user for downloading.
NOTE: The project is based on Python 2.7.15 plateform running it on any other plateform might create some issues.
Create a python3 virtual environment to run the file that helps in uploading and downloading file from the google drive.
Step 1: Install Requirements
pip install -r requirements.txt
Step 2: Run the application
python app.py
Step 3: Visit the localhost from your browser
Step 4: Enjoy :)
