Design and Educational Implementation of a Web-Based Hybrid Encryption System Using Django
Year: 2026
Type: article
Abstract: The increasing reliance on web applications for handling sensitive user data has made application-level security a critical requirement. Although cryptographic algorithms are well established, their practical integration into web frameworks is often limited to theoretical demonstrations or isolated scripts. This paper presents the design and implementation of a web-based encryption system developed using the Django framework to demonstrate the practical application of cryptographic techniques in a real-time web environment. The system allows authenticated users to perform secure text encryption and decryption using symmetric algorithms such as Advanced Encryption Standard (AES) and Triple Data Encryption Standard (3DES), while RSA is employed for secure symmetric key protection. Additionally, SHA-256 hashing is used to ensure secure password storage and user authentication. Experimental observations conducted on varying input sizes indicate that AES provides lower computational overhead compared to 3DES, while hybrid encryption introduces additional processing cost due to asymmetric key operations. The primary objective of this work is to provide an educational and practical reference for implementing cryptography within web applications. The results confirm that established encryption algorithms can be effectively combined with modern web frameworks to achieve secure and user-accessible data protection. This work is intended primarily as an educational and practical implementation reference rather than a proposal of new cryptographic algorithms.
