This project demonstrates the implementation of encryption and decryption mechanisms using parallel processing techniques in C++. By leveraging both multiprocessing and multithreading, the project aims to enhance the efficiency and performance of cryptographic operations.
The repository contains two primary branches, each focusing on a distinct parallel processing approach:
Description: This branch showcases the use of parallel multiprocessing by creating child processes to handle encryption and decryption tasks. It utilizes the fork() system call to spawn child processes, enabling concurrent execution of tasks.
Key Features:
- Process Management: Implements process creation and management using
fork(). - Task Queue: Manages encryption and decryption tasks using a queue structure.
- Task Execution: Child processes execute tasks independently, allowing parallel processing.
Description: This branch focuses on multithreading combined with shared memory to perform encryption and decryption. It employs POSIX threads (pthread) and utilizes shared memory segments for efficient inter-thread communication.
Key Features:
- Multithreading: Implements concurrent execution using POSIX threads.
- Shared Memory: Utilizes shared memory for communication between threads.
- Semaphores: Employs semaphores to manage synchronization and ensure data consistency.
To explore the implementations in each branch:
git clone <repo-url>
cd encrypty
git checkout <branch>
# Now make a virtual env and activate
python -m venv /myvenv
source myvenv/bin/activate
python makeDirs.py
make
./encrypty
# type directory name which is created from makeDirs.py
test
ENCRYPT # after giving directory name, give ENCRYPT or DECRYPT to tell what to do
