Qrkey – Offline private key backup on paper

In plain words

Qrkey is a tool for backing up private cryptographic keys on paper using QR codes. It converts private keys into QR code format that can be printed and stored offline, providing a physical backup method for users who need to secure sensitive cryptographic material. The tool is designed for developers and cryptocurrency users who want an air-gapped storage solution independent of digital storage devices.

qrkey is a command-line tool for generating and recovering QR codes from files for offline private key backup. It allows you to convert files into QR codes that can be printed or stored, and later recovered from those QR codes. It supports large files by splitting them into multiple QR codes, and includes metadata for easy recovery and validation. docker run -v " $( pwd ) " :/mnt ghcr.io/techwolf12/qrkey:latest generate --in /mnt/testfile.txt --out /mnt/test.pdf For other systems, see the releases page . qrkey generate --in < file > --out file.pdf To recover a file from QR codes, use the following command: qrkey recover --in < file.txt > Or to recover interactively: qrkey is a command-line…from github.com

  Paranoid Qrypto2025 · paranoidqrypto.com · ▲7

  Built an offline encryption tool for people who don't trust cloud services or hardware wallets. Paranoid Qrypto runs completely offline (air-gapped). You type your seed phrase on an offline device, and it encrypts it using Argon2id + AES-256-GCM. The encrypted file can be stored anywhere USB, cloud, printed as QR code without exposing your keys. Why this was build: Hardware wallets cost $100-200 and are single points of failure * Cloud solutions require trusting a third party * Paper backups have no protection if found Technical details: * Runs in browser with no server calls * All…

  I made a privacy-first minimalist Backblaze2022 · blobbackup.com · ▲236

  Creator here. I was looking for something as simple as Backblaze Personal [1] but privacy focused and open source. This is my attempt to build that. Uses PyQt6 [2] for the GUI and Pyinstaller [3] for creating the platform specific binaries. The backup engine under the hood is Restic [4]. The server code is written in Laravel [5]. All the code is on GitHub [6]. I actually really like Backblaze (even use B2 for this offering behind the scenes) so this isn't meant to throw shade their way. Just wanted a private open source alternative. Something like Bitwarden but for backups. [1]…

  I'm an airline pilot – I built interactive graphs/globes of my flights▲1,539

  Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https:&#x2F;&#x2F;jameshard.ing&#x2F;pilot&#x2F;globes&#x2F;all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  Workout.cool – Open-source fitness coaching platform▲827

  I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits&#x2F;month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
