Privsen – Zero-knowledge encrypted sharing without signup or trust

Summary: Privsen is a privacy-focused toolkit that encrypts data client-side using AES-256-GCM before upload, ensuring the service cannot access user files. It supports encrypted file sharing up to 15GB, self-destructing messages, anonymous polls, and encrypted chat rooms without requiring accounts.

What it does

Privsen encrypts files and messages in the browser, with decryption keys stored only in the URL fragment, preventing server access. It enables sharing encrypted files, self-destructing secrets, anonymous polls with fraud detection, encrypted group chats, and metadata stripping from images and PDFs.

Who it's for

It is designed for users seeking secure, zero-knowledge data sharing without trusting cloud providers or creating accounts.

Why it matters

Privsen eliminates the need to trust service providers by ensuring they cannot access or decrypt user data, addressing privacy and security concerns inherent in traditional cloud services.
