    dotNet Disk Imager

    dotNet Disk Imager

    Lightweight RAW and ZIP disk images reader and writer to USB or SD

    IMPORTANT!!! Since this is new software, your web browser, operating system or even possibly antivirus software may report security alerts against this tool. Please ignore that messages until this tool gets widely spread. This program is highly inspired by Win32 Disk Imager and sort of copies it's function. However, I've added some features, like verification of readed/writed image file and the most important is on the fly support for zipped images. Another features worth mentioning are simultaneous write to multiple devices at one time or wiping of device filesystem and partitions. I would be happy to hear your feedback and I'm ready to listen to your suggestions. Feel free to request new features, if I found them interesting I will definitely implement them. Requires .NET Framework 4.6.1 (download here: http://go.microsoft.com/fwlink/?LinkId=671729 ) Supports Windows 7 and newer. If you need older Windows support, use Win32 Disk Imager. Please write a review.

    A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

    2Pix
    2Pix integrates with Windows to allow you to easily encrypt and hide files in bitmap images, a process called steganography (not to be confused with stenography). Data is stored in the low-order bits of each pixel of an image, so the file is completely hidden from view. Version 1.1 now provides plausible deniability because no unencrypted signature is stored in the image header. It should be impossible to prove an image contains a hidden file (if you use a strong password and only use 1 or 2 bits per pixel component). NOTE: This project has been moved to Google Code. http://code.google.com/p/2pix-steganography

    Electronic Shelf Label Management System

    Electronic Shelf Label Management System

    DIY Electronic Shelf Label Management System

    This ESL management system incorporates the electronic shelf labels and the ESL management software. The ESL management software enables you to manage your electronic shelf labels. It accomplishes this by maintaining a database with the credentials of each ESL and the last image that was sent to it. When you choose the image to be displayed on the ESL and hit the "Send Image To ESL" button, the software encrypts that image, sends it to the specified ESL over Wi-Fi using the UDP protocol, and then saves it to the database. An electronic shelf label is a device that displays relevant product information, they're usually attached to the front edge of retail shelving. A typical ESL consists of a display and a simple microcontroller that controls the display. *V2.0 now supports ESP32 CYD You can learn more on: Github: github.com/Northstrix/Electronic-Shelf-Label-Management-System Instructables: https://www.instructables.com/DIY-Electronic-Shelf-Label-Management-System-V20/
