To achieve this with vanilla JS requires a deep dive into several modern browser APIs. Firstly, the File and FileReader APIs allow the browser to read large files from the user's system. However, transferring these files securely requires more than just reading data; it requires encryption. This is where the Web Crypto API becomes essential. A developer utilizing vanilla JavaScript can implement client-side encryption (such as AES-GCM) before a file ever leaves the user's computer. This ensures that even if the transfer medium is compromised, the data remains secure—a concept known as "end-to-end encryption."
