Data Hashing Tool Development

@misbahoffical

Hello, I can build a simple desktop app that hashes files with SHA-256, saves results to SQLite, and compares new hashes against the stored ones. You’ll get a clean GUI with a file picker (and drag-drop), progress/status, and clear results—packaged as a Windows .exe and a Linux build for Ubuntu. I’ve delivered similar cross-platform tools using Python (PyQt + PyInstaller) and C#/.NET (Avalonia), with solid experience in cryptographic hashing and SQLite.

Hi there I am C++ Developer with over 25 years of experience incuding: 1) Both Windows Desktop application development and Linix application development 2) cross-platfom GUI libraries like wWidgets and Qt 3) Exprience with SQLite 4) Experience with SHA 256 I have few questions about project I would like to clarify.

@gowthamsarathy

Hi there yeah I'm expert in SHA-256 Algorithm and I can create you a .exe application for sure Kindly send me a message we'll discuss further Really Looking forward to hear you Thank you

@oscarchaparro01

Hi there, I can develop a cross-platform application that generates SHA-256 hashes for files, works on both Windows and Ubuntu, and saves the results in a .sqlite database for later comparison. Key points of my approach: Cross-platform compatibility: I’ll build the app so it runs smoothly as a Windows .exe and as a Linux executable. User-friendly design: A clean file selection dialog so users can easily choose one or multiple files. Hashing + storage: Each file’s SHA-256 hash will be generated and saved into a .sqlite database, with functionality to compare new results against previously stored hashes. Maintainability: Well-structured code with clear documentation so the application can be extended later if needed. I have hands-on experience with file hashing, database integrations, and packaging applications for both Windows and Ubuntu. Happy to share examples of similar projects I’ve delivered. Looking forward to discussing details like UI style, reporting format, and timeline. Best regards, Oscar

This kind of project excites me. Creating a .exe application for Windows and Ubuntu that hashes file data with SHA-256 sounds challenging and interesting. I can deliver exactly what you're looking for. I have extensive experience creating cross-platform executable files and am well-versed in the complexities of the SHA-256 algorithm. User-friendly interfaces, including file selection dialogues, are my specialty, ensuring a seamless experience for your users. 100% refund if I fail to deliver. Simple as that. Thanks, Alex

@rajubhalani

Stavros, for the Data Hashing Tool Development project, would it be fine if I create a user-friendly .exe application for Windows and Ubuntu that efficiently hashes file data using the SHA-256 algorithm, ensuring seamless saving of hash results into .sqlite files for easy comparison later on? So I believe this approach will streamline the process of securely hashing file data, providing a reliable tool that meets your requirements effectively. By the way, have you already identified the specific criteria for file selection in the user interface, or would you prefer a more customized approach to enhance the overall usability of the application?
