SecretVoid

What it does

Stop sharing credentials in plain text. SecretVoid turns any secret into a self-destructing link - opened once, then gone forever. Your secret is encrypted in your browser before it reaches us. Not even SecretVoid can read what you share. Burn after reading and time-based expiry, password protection, read receipts, no account required. Built for anyone sharing API keys, passwords, or credentials that should only reach the intended recipient.

Share passwords, API keys and credentials via self-destructing links. SecretVoid uses two independent layers of AES-256-GCM encryption — your browser encrypts first, our server encrypts again. Neither layer alone is sufficient to decrypt. No account required.

Your browser encrypted this. The server never sees plaintext. Your secret is encrypted in your browser using AES-256-GCM. The decryption key stays in the URL fragment (#) and never reaches our servers. We encrypt your already-encrypted secret again with our own server key. Two layers protect against different attack vectors. Secrets self-destruct after reading or when the timer expires. Once gone, they're gone forever - even we can't recover them. Not even we can read your secrets. Your secret is encrypted in your browser before reaching us. We then encrypt it again with our own server key. We mathematically cannot decrypt what you share - we only ever see encrypted data. If our servers…from secretvoid.com

  Instantly pass your passwords securely2019 · ▲31

  Hey HN! I made a service to share passwords easy and secure but never promoted it. It's called instapass.io I noticed that people besides my friends and clients actually started to use, so maybe it will be helpful for you too! You share one-time self-destruct message using one time links and I won't even be able to see what you wrote. How does it work? When you generate a message the client-side makes a random password and use that to encrypt the message. The password is appended as an anchor tag which all modern browsers never send to the server. This way, I don't even know what you shared.…

  Flashpaper – Self-destructing secret sharing with no databaseJul 2026 · flashpaper.app · ▲25

  Hi everyone! This is my first HN and I’m very new to the scene. My name is Min from Bangkok. At first, I just want to create a dead man's switch for personal use and for fun. then, I think about information that self destruct like a spy movie. after that, I try to come up with the better version of Privnote or Bitwarden with self-destruct and some kind of censoring or blocking download ability. Somehow, end up with this product. :O Flashpaper is for sending any information that would be burned after reading (with counting down timer like Mission Impossible movie ! or after 24 hrs max if not…

  Talanoa▲343

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
