End-to-End Encrypted File Sharing Web App
Approx. component budget: Rs. 0 - 2,000
Objective
Let two people share files so that the server never sees the content or the key.
What you will build
A website to share files using a link and a key, where files are encrypted in the browser before upload and expire after a set time or download count.
Results you can expect
- Correct decryption on large files up to 100 MB
- Key never sent to the server (verified by network logs)
- Expiry working
- And upload speed vs file size
What you will learn
Hybrid encryption, key sharing through the URL fragment, streaming large files, and secure deletion rules.
Tools and notes
Web Crypto API, Node.js, free object storage tier, browser developer tools for verification.
Resume points from this project
- Built and tested End-to-End Encrypted File Sharing Web App; objective: let two people share files so that the server never sees the content or the key.
- Measured and analysed correct decryption on large files up to 100 MB and key never sent to the server (verified by network logs); wrote the report and presented the results in a viva. Add your own numbers: [x].
Replace [x] with your own measured results. Write only what you really did.
