Secure File Transfer Using Hybrid Cryptography-Based Web App

Abstract

Secure file management has become a key concern in the current digital landscape, where sensitive information is exchanged and stored regularly for personal, academic and sprofessional activities. In addition to holding such sensitive information as business contracts, health records, legal documents and financial information, the potential for confidentiality of these types of information is increasing due to cyber threats from unauthorized access, phishing attacks, ransomware and insider leaks. The above-mentioned data risks demand effective systems to protect files from being tampered with, stolen or misused, while at the same time allowing users to continue access and control of the files they create or manage.

Typical file storage solutions have restrictions on how securely they can provide file storage and may use proprietary methods of encryption/security that lack transparency and strong encryption/protective controls, thus exposing confidential information  to potential data breaches. The mentioned  problems can be solved through cryptography by using systematic methods to convert human-readable information  into  unreadable but secure formats to ensure the confidentiality, integrity, and authenticity of the information stored.
