Contributions
(1)
Developed a web-based file encryption/decryption app using React.js and AES (Rijndael) with 128/192/256-bit key support.
(2)
Implemented AES-CBC mode encryption with random IV generation and PKCS7 padding.
(3)
Integrated SHA-256 checksum verification to detect file corruption or invalid decryption keys.
(4)
Supported multiple file formats — documents, images, audio, and video.
(5)
Implemented PBKDF2 key derivation with random salt and 10,000 iterations.
(6)
Added file size validation to prevent browser memory overflow.
CONTEXT
AES (Advanced Encryption Standard), originally known as the Rijndael algorithm designed by Vincent Rijmen and Joan Daemen of Belgium, was adopted by NIST in 2001 as the new cryptographic standard, replacing DES. CipherFile is a web-based file encryption and decryption tool that allows users to securely encrypt and decrypt files directly in the browser using AES, without transmitting or storing any data on a server.
