    Decimen Optical Transfer

    Decimen Optical Transfer

    Fountain-coded QR file transfer

    Decimen Optical Transfer is a browser-based proof of concept for moving files between devices through animated QR codes. A sending screen continuously displays encoded frames while a receiving camera captures enough of them to reconstruct the original payload. The system requires no direct network path, pairing process, native application, or permission beyond camera access. Fountain coding makes the stream tolerant of missed, blurred, duplicated, and out-of-order frames without requesting retransmission. Each QR frame includes session and file metadata, allowing a receiver to join an active stream or reset when a new session begins. QR decoding runs through zxing-cpp compiled to WebAssembly and uses workers to process camera frames efficiently. Configurable settings control payload size, transmission speed, QR density, capture resolution, and worker count, while a final hash verifies the recovered file.

    QRCoder

It hasn't any dependencies on other libraries and is available as .NET Framework and .NET Core PCL version on NuGet. Feel free to grab-up/fork the project and make it better! QRCoder is a .NET library, completely written in C#, which enables you to generate QR Codes as defined by ISO/IEC 18004. The main target of the QRCoder library is to deliver a small and easy-to-use solution, which has no dependencies to other libraries or network stacks. (Like QR Code generators which are relying on online services which makes them vulnerable/slow in some cases.) Although simplicity is one of the main goals, QRCoder is really flexible, in both "output formats" as well as in "payload types". Payload types? Yes, QRCoder brings its own "payload generator", which helps you to create a big list of different payload types to generate special QR codes like "WiFi QR Codes", "Girocodes", "SwissQRCodes" and many more.

    BDE QR Generator

    BDE QR Generator

    Offline QR code generator for BDE

    Most QR codes are just text. When scanned with a USB reader, the reader just types out the text really quickly. It's difficult to type in a 55-character bitlocker key. This tool will create a QR code from a bitlocker key so you can plug a 2D barcode scanner into the affected computer, then scan the picture from the program. There's a section to allow you to create a QR with some cmd code to simplify the unlock and even delete a file. You can keep concatenating with &&. The screenshots section should show you everything you need to start using it. Crucially, this does not use any web api calls. It can run offline. I'm not a coder so this isn't error handled anywhere near as well as it should. Source is in the files section. Built on QRCoder by Raffael Herrmann, released under MIT license. https://github.com/codebude/QRCode
