Burner Note▲222In 2021 after getting thoroughly sick of Privnote, i built "Burner Note". Even though i didn't promote it in anyway other than a post here and a post on reddit, it ended up getting about 7000(ish) unique users per month. I kinda let it die about 18 months ago but i've resurrected it with some big upgrades. Most botable the app is now truly end to end encrypted (previously was just server side), and I've added dark mode as well as a few other bells and whistles. Feedback welcomed.

Hey HN, I'm so happy to finally show you all this release after years of hard work. I posted the first version of EnvKey to HN back in 2017 (https://news.ycombinator.com/item?id=15330757), then went through YC in W18 (https://news.ycombinator.com/item?id=16569534). EnvKey is an end-to-end encrypted configuration and secrets manager. It protects your organization's API keys, encryption keys, credentials, and other secrets, and makes it easy to run servers, scripts, tests, and everything else with the latest config. It also helps you avoid duplication in your…

Stasher is a tiny CLI tool that lets you share encrypted secrets that burn after reading — no accounts, no logins, no servers to trust. I built it because I just wanted to share a password. Not spin up infra. Not register for some "secure" web app. Not trust Slack threads. Just send a secret. Secrets are encrypted client-side with AES-256-GCM. You get a `uuid:key` token to share. Once someone reads it, it's gone. If they don't read it in 10 minutes, it expires and deleted. Everything is verifiable. Every release is signed, SLSA-attested, SBOM-included, and logged in the Rekor transparency…

iKrypt▲5Hi HN I built iKrypt after realizing how often passwords, API keys, and other sensitive info still get shared over Slack DMs or email with “I’ll delete it later”. iKrypt is a zero-knowledge, one-time secret sharing tool: - Secrets are encrypted in the browser - The server stores only ciphertext - The decryption key lives only in the URL fragment (never sent to the server) - Links expire by time or view count - Optional email notification when a link is first opened This is intentionally not a password manager or vault — it’s for quick, one-off handoffs where you don’t want sensitive data…

I built a tool called *Kekkai* for file integrity monitoring in production environments. It records file hashes during deployment and later verifies them to detect unauthorized modifications (e.g. from OS command injection or tampering). Why it matters: * Many web apps (PHP, Ruby, Python, etc.) on AWS EC2 need a lightweight way to confirm their code hasn’t been changed. * Traditional approaches that rely on metadata often create false positives. * Kekkai checks only file content, so it reliably detects real changes. * I’ve deployed it to an EC2 PHP application in production, and it’s working…

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.…
