BlindLock
The invisible password vault, hidden in an ordinary image
BlindLock keeps passwords, notes & 2FA encrypted in an ordinary PNG on your device. Traditional cloud vaults are giant targets. Your vault is cryptographically bound to your hardware (TPM 2.0/Secure Enclave) with strict process isolation—the main app has zero network libraries. 7-day trial, no account required. Grab one of 1,000 lifetime licenses before subscriptions start!
Hi Product Hunt!
I'm David, the solo developer behind BlindLock.
I built BlindLock because I was tired of centralized cloud password managers acting like giant, obvious targets for data breaches. I wanted something genuinely local, so I spent my hyperfocus building an alternative based on steganography.
BlindLock hides your encrypted vault inside an ordinary PNG photo. But my real focus is the security architecture under the hood:
* Hardware-Bound: The keys are tied directly to your physical hardware (TPM 2.0 / Secure Enclave). It intentionally fails in VMs.
* Strict Process Isolation: The main app has absolutely zero network libraries. All mandatory update, license, and kill-switch checks route through a heavily restricted helper process.
* Your Data Stays Put: Vault contents never leave your machine. There is no central vault database — nothing to breach on my end.
One thing I want to be upfront about: "local" describes where your data always stays — on your machine, and nowhere else. It does not describe whether the app ever goes online. BlindLock does connect before unlocking — for the license and mandatory update check, and for the kill switch that lets you revoke a stolen device. Your vault contents are never part of that.
As a solo dev with Asperger's, I want to remain 100% independent from investors so I can focus purely on the software. That's why I'm offering a limited run of 1,000 lifetime licenses to fund the development before strictly transitioning to a subscription model.
I'd love to hear your thoughts on the isolation architecture, the hardware-binding, or the steganography approach. I'll be here all day to answer your questions!
