SecureCrypt: A Hybrid Encryption System for Secure Data Transmission, In an era of increasing data breaches and cyber threats, traditional cryptographic methods often fall short against modern attacks., “SecureCrypt” is a cutting-edge cybersecurity project led by Aditya Shrivastava that focuses on building a hybrid encryption system combining both symmetric (AES) and asymmetric (RSA) encryption techniques to provide confidential, authenticated, and efficient data communication., This project implements a secure platform where:, 1. The message is encrypted using AES-256 for fast encryption of large data., 2. The AES key is then encrypted using RSA-4096, ensuring secure key exchange., 3. The system also includes digital signatures to verify sender authenticity and hashing (SHA-256) to ensure data integrity., 4. SecureCrypt provides a GUI interface for users to encrypt/decrypt files or text, and securely share them over untrusted networks., Key Features:, 1. AES-256 encryption for data confidentiality, 2. RSA-4096 encryption for secure key exchange, 3. Digital signature for sender verification, 4. File encryption support, 5. SHA-256 integrity check, 6. User-friendly GUI using Python & Tkinter / PyQt, 7. Optional integration with cloud services for secure file sharing, Cybersecurity Project – SecureCrypt, Role: Project Lead | Name: Aditya Shrivastava, 1. Designed and led the development of SecureCrypt, a hybrid encryption system combining AES-256 (symmetric encryption) and RSA-4096 (asymmetric encryption) for secure data transmission., 2. Integrated digital signatures and SHA-256 hashing to ensure authentication and integrity of files and messages., 3. Developed a user-friendly GUI application in Python enabling encryption, decryption, key generation, and secure file sharing., 4. Oversaw the complete system architecture, security logic, and deployment, ensuring high performance and adherence to modern cryptographic standards., 5. Demonstrated strong leadership in cryptographic application design, secure software development, and practical implementation of cybersecurity principles.
