Cada vez que arrancamos Autofirma en Windows perdemos tiempo revisando uno a uno los certificados digitales instalados. Necesito una pequeña aplicación con interfaz gráfica que se abra sobre, o junto a, Autofirma y me permita localizar al instante el certificado correcto escribiendo simplemente el nombre o el DNI del titular; elijo uno de esos dos campos y la herramienta debe filtrar la lista y posicionarme directamente sobre el certificado correspondiente, listo para firmar. Requisitos clave • Plataforma: Windows (-solo me interesa esta versión). • Métodos de búsqueda: nombre y DNI, ambos en la misma ventana. • Interfaz: gráfica, ligera y de ejecución sencilla (un único .exe sería perfecto, sin instalaciones complejas). Espero como entregables: - Ejecutable funcional. - Código fuente bien comentado. - Breve guía de uso y, si es necesario, instrucciones de instalación de dependencias. El desarrollo puede estar en el lenguaje que prefieras (por ejemplo C#, Python con PyInstaller, o Java), siempre que cumpla con el arranque rápido y la compatibilidad con Autofirma. Testearé la solución seleccionando varios certificados: si al introducir nombre o DNI el programa coloca automáticamente el foco en el certificado correcto, el trabajo se considerará aceptado.

Hello there, Desarrollaré la aplicación de escritorio en C# (.NET) — un único .exe portable que lee el almacén de certificados de Windows, filtra por nombre o DNI en tiempo real y posiciona el foco sobre el certificado correcto en Autofirma mediante UI Automation. Usaré la API `X509Store` para acceder al almacén personal y extraer el campo Subject de cada certificado, parseando nombre y DNI del campo serialNumber del DN — así el filtrado es instantáneo sin dependencias externas. Questions: 1) ¿Autofirma se ejecuta con permisos de administrador o como usuario estándar? 2) ¿Los certificados están en tarjeta criptográfica (DNIe) o importados en software? Looking forward to discussing further. Best regards, Kamran

Hi, this project requires a focused Windows utility to streamline certificate selection alongside Autofirma, a scenario that demands precise UI integration and quick filtering capabilities. The real engineering risk lies in reliably accessing and interacting with Autofirma's certificate store and UI context without disrupting its workflow. I usually design systems by isolating data retrieval from user interaction layers to maintain responsiveness and simplify maintenance. Building a lightweight executable with minimal dependencies is straightforward but requires careful handling of Windows certificate APIs and UI focus management. While this project does not involve AI or backend orchestration, my experience in integrating custom features into existing software and working with C# environments equips me to deliver a robust, maintainable solution. I approach such systems with an eye toward long-term usability and clear documentation to facilitate future updates or handoffs. I can outline the certificate retrieval pipeline, map the UI interaction flow, and draft a deployment plan to ensure seamless integration with Autofirma. Thanks, Hercules

Hola Para crear un buscador de certificados para Autofirma, lo más importante es que la herramienta no solo encuentre el certificado, sino que lo seleccione de forma estable dentro de la ventana correcta. Mi enfoque sería construir una aplicación ligera para Windows que lea los certificados instalados, permita buscar por nombre o DNI, filtre resultados en tiempo real y después intente posicionar el foco en Autofirma usando automatización de interfaz cuando sea posible. El punto crítico será validar primero cómo Autofirma expone la lista de certificados, porque una integración basada solo en clics o coordenadas puede fallar entre equipos, resoluciones o versiones. Esto significa que entiendo que el objetivo es ahorrar tiempo diario con una utilidad rápida, simple y confiable, no crear una aplicación grande. Mi proceso empieza con una prueba técnica sobre Autofirma, luego interfaz de búsqueda, lógica de certificados, selección automática, empaquetado en .exe, pruebas y guía breve. If it aligns with you, let’s discuss in detail via private chat.

Two details stood out: you want a single .exe with no complex install, and the acceptance test is concrete (type a name or DNI, the tool focuses the right certificate in Autofirma). I would start with a 2-day spike to read the Windows certificate store and confirm the focus-injection approach against your Autofirma version. Build plan: 1. C# WinForms app reading certificates from the Windows store (CurrentUser + LocalMachine), parsed for CN and DNI from the Subject. 2. Single search window with two radio fields (Nombre / DNI), live filter as you type, results sorted by match quality. 3. On selection, the app brings Autofirma to front and pre-selects the matching certificate (via UI Automation if Autofirma is already open, or by launching it with the chosen cert). 4. Packaged as a single .exe with ILMerge, no installer required. I have shipped Windows desktop utilities that integrate with the certificate store and drive third-party apps via UI Automation, so the focus-injection step is the known-tricky part I would validate first. Deliverables: working .exe, commented C# source, and a short PDF guide. Done = typing a name or DNI focuses the correct certificate in Autofirma, verified on your machine with several test certificates. Timeline: 7 days. Price: €162 fixed. One question: is your Autofirma launched standalone, or always triggered from a browser/PDF signing flow? That changes how I wire the focus step. P.S. Autofirma's certificate dialog is a JavaFX window, not native Win32, so standard SendKeys won't work reliably. I would use UI Automation against the JavaFX accessibility bridge, which most bidders will miss until day 3. Waqar

Hola buen día. Analicé el requerimiento para el buscador de certificados de Autofirma. Se como desarrollar tu idea y que sea funcional. Propuesta: Tecnología: Desarrollaré la aplicación en C# (.NET). Es la mejor opción para Windows ya que genera un único .exe nativo, muy rápido y sin requerir la instalación de entornos pesados como Python. Lógica: Usaré la API nativa X509Store para leer los certificados del sistema. La interfaz tendrá un buscador fluido en tiempo real (por Nombre o DNI). Interacción: Para interactuar con Autofirma, utilizaré UIAutomation de Windows, detectando la ventana de selección de certificados para inyectar y posicionar el foco automáticamente en la opción correcta. Entregables: Código fuente bien comentado, el ejecutable portable y una breve guía de uso. Pregunta: Para mayor agilidad, ¿desea que la herramienta se ejecute minimizada en la bandeja del sistema (System Tray) y se active mediante un atajo de teclado cuando usted abra Autofirma, o prefiere abrir el .exe manualmente en cada uso?
