Python Cryptography Algorithms - Data Encryption

This project demonstrates the implementation of various cryptographic algorithms, including AES, DES, ECC, and Blowfish, using Python. A sample dataset (amazon.csv) is encrypted using each algorithm, and the encryption performance, including average time per row and total encryption time, is recorded.

The encrypted data is stored in a binary file (encrypted_data.bin). Additionally, the public and private keys for the ECC algorithm are generated and stored as public_key.pem and private_key.pem.

Project Structure

• Dataset: amazon.csv (Sample dataset used for encryption)
• Encrypted Data: encrypted_data.bin (Stores the encrypted data in binary format)
• Keys:
  • public_key.pem (ECC public key)
  • private_key.pem (ECC private key)

Cryptographic Algorithms Implemented:

• AES (Advanced Encryption Standard)
• DES (Data Encryption Standard)
• ECC (Elliptic Curve Cryptography)
• Blowfish

Features

• Implements encryption using AES, DES, ECC, and Blowfish algorithms.
• Measures and calculates:
  • Average encryption time per row.
  • Total time taken to encrypt the dataset.
• Encrypted data is saved in a binary file for secure storage.

How to Run the Algorithms

Each algorithm has its own Python file. You can run an algorithm by using the following command in your terminal:

python <algorithm_file.py>

Example (Running ECC Encryption):

python ecc.py

Files

• aes.py: AES encryption implementation.
• des.py: DES encryption implementation.
• ecc.py: ECC encryption implementation.
• blowfish.py: Blowfish encryption implementation.

Prerequisites

To run the project, you need to have Python installed on your system along with the following libraries:

pip install pycryptodome cryptography

Sample Dataset

The sample dataset used in this project is amazon.csv. You can replace this file with any CSV dataset of your choice to test encryption on different data.

Performance Metrics

For each algorithm, the project calculates and displays:

• Average Time per Row: The average time taken to encrypt each row of the dataset.
• Total Encryption Time: The total time taken to encrypt the entire dataset.

Usage Notes

• The encrypted data is stored in the encrypted_data.bin file. This file is in binary format for secure data handling.
• Public and private keys generated during ECC encryption are saved in public_key.pem and private_key.pem, respectively.
