SECURE FILE TRANSFER USING AES & RSA ALGORITHMS

Abstract

The project titled "Secure File Transfer Using RSA and AES Algorithms" aims to develop a secure, efficient, and user-friendly system for transferring files over a network. It uses a hybrid cryptographic approach by integrating AES, a symmetric encryption algorithm, and RSA, an asymmetric encryption algorithm, to ensure both the confidentiality of the file and the secure transmission of the encryption key. In this system, the file content is encrypted using AES for fast and strong encryption, while the AES key is securely encrypted using RSA before being shared with the receiver. The receiver then decrypts the AES key using their private RSA key and uses it to decrypt the actual file. This dual-layered encryption model ensures that the file can be transferred safely even over an insecure or public network.
