Iberbox Secret

Share passwords & secrets via self-destructing one-time link

What it does

Stop sharing passwords over email or chat — they stay in logs forever. Iberbox Secret lets you share passwords, API keys, and confidential notes via a unique link that self-destructs after being read once. Key features: • One-time links: secret deleted after first view • End-to-end AES-256-GCM encryption • Optional passphrase protection (max 5 attempts) • Configurable expiry: 30 minutes to 7 days • Zero-knowledge architecture • No account required. Free. No limits.

    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…

    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.…

    With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
