Show HN: Encrypter.site – Browser-based E2E encryption for text and files

[zealer]

I built a simple tool for encrypting text and files entirely in the browser.

- AES-256-GCM encryption with PBKDF2 key derivation (600k iterations by default) - Supports text and file encryption (up to 256MB) - Data never leaves your device - Share encrypted content via QR code or link - No account, no server storage, no tracking

The crypto is handled by the Web Crypto API, and the source is straightforward if anyone wants to take a look. Would love feedback on the UX and any edge cases I might have missed.

I've played with/built a few browser based encryption tools. What always bothers me is that it boils down to "trust me, I won't send your data anywhere" in a tool with the primary function of sending and receiving data to/from remote servers

That's a valid concern and the classic 'chicken and egg' problem of web-based cryptography. You effectively have to trust the delivery mechanism (the server) every time you load the page. My goal wasn't to replace GPG or Signal for high-stakes whistleblowing, but to lower the friction for ad-hoc sharing. Sometimes you just need to send a password or API key to a coworker, and the alternative is often sending it in plaintext via Slack/Email because setting up PGP is too much friction for the other party. To mitigate the trust issue as much as possible, I've kept the source minimal and readable so it can be easily audited in the 'View Source' or DevTools.

Nice work on the implementation! The client-side-only approach is solid for trust.

Thanks! By the way, I just launched a Time Capsule feature. Would love to have you try it out!
