Products that do what Hidetext.sh – encrypted pastebin where the server never sees the key does
Hi HN! I built hidetext.sh — a way to share text, code, and files through links the server can't read. How it works: your browser generates a random key and encrypts everything locally (NaCl secretbox, XSalsa20-Poly1305). Only ciphertext is uploaded. The key goes into the URL fragment — the part after # — which browsers never send to servers. The link carries the key, my server stores the locked box, and the two only meet in a browser. A design detail I'm fairly happy with: burn-after-read doesn't destroy the paste on the first HTTP request. The naive version means a Slack or iMessage link…

I thought it would be great to share code snippets without saving them on a server, so I created http://mem.pe It allows you to paste code and save it in your browser's local storage. When you share the URL of the pasted code, other people will connect to it via web sockets. For example, this http://mem.pe/#sge/5 you will be pulling from my browser. I'll keep it open for a while. If you close the web app, your code paste will not be available for anyone to see, until you open the web app again. This is obviously, not suitable for using at forums and other places…

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.…

I've had issues saving bookmarks on my computer since my girlfriend always uses it. I'm talking about engagement ring related bookmarks, birthday plans related bookmarks, etc. My buddy and I built an extension called Hush that allows you to save them behind a password of your choosing. They're encrypted using SHA-256/AES, and you can export/import them to your liking (in case someone accidentally uninstalls the extension). It only operates in private browsing for security reasons. Check it out and let us know what you think! Chrome link:…

Hey HN, We're building ncrypt, an open-source encrypted file manager that allows you to store, manage, and privately query your files using fully homomorphic encryption (FHE). This project originally started as a simple SFTP-like CLI for my personal S3 buckets which I used to send and retrieve encrypted files and have more granular control over key rotation. As the number of files that I was storing grew, file discovery started to become a problem, and I found myself frequently having to download and decrypt files to inspect their contents. Rather than leaving them unencrypted in S3 and…

I've created a quick application that stores data in IPFS (http://ipfs.io) which is a distributed web implementation. It's working as expected, paste some content, get a hash in the url and send to a friend. The content will be there forever and distributed to peers that asks for it. Demo: http://ipfsbin.xyz/#QmXdMvJaRrSTCAcDFMZLUFfm9uGK6Wq7qEVcwbvaQRxq8x This have a couple of advantages, mainly that the same content would have the same hash, meaning that things wouldn't be duplicated. Source is available for people interested in that here:…
