Turns any Linux server into a central WSS endpoint for a\nLAN-attached signotec pad (Sigma / Omega / Gamma / Delta / Alpha / Zeta).\n\nBrowser clients talk HTTPS/WSS to a TLS-terminating reverse proxy of your\nchoice (Apache, Nginx, Caddy, …), WS traffic gets proxied into the\ncontainer, and the container speaks TCP/IP to the pad on the LAN.\n\n## Why not the official Linux build?\n\nsignotec does ship `signoPAD-API/Web` for Linux as well\n(`signoPAD-API_Web_Linux_3.5.0.zip`), but that build only implements\n**Default mode**. Default mode can capture a signature, but **cannot\ndisplay a PDF on the pad** — the recipient just sees a bare \"please sign\"\nscreen. That defeats the whole reason for buying a large Delta 10.1 in\nthe first place.\n\nThe **Windows build** of `signoPAD-API/Web` implements the full\n**API mode**: load PDF onto the pad, scroll, sign directly on the\ndocument. Exactly what most workflows actually need.\n\nThe fix: pack the Windows build into an Ubuntu + Wine container and run\nit on the Linux server. In hands-on testing, every relevant command\ngoes through cleanly: `searchForPads(IP=...)`, `Device.open`, `Pdf.load`,\n`Display.setPDF`, `Signature.confirm`, `Signature.saveAsStream`.\n\n## Build \u0026 run\n\nOnly the host needs `docker` — the Dockerfile fetches and extracts the\nsignotec installer itself.\n\n```bash\ndocker build -t signotec-stpadserver:wine .\n\n# manual one-shot run (host network so the container can reach the pad LAN)\ndocker run --rm --network host signotec-stpadserver:wine 0.0.0.0 49494\n```\n\nOr in one go, including systemd + Apache reverse proxy:\n\n```bash\nsudo bash install.sh\n```\n\n## What happens during `docker build`\n\nThe Dockerfile is multi-stage:\n\n* **Stage 1 (extract)** — downloads\n  `signotec_signoPAD-API_Web_3.5.0.exe` from\n  [downloads.signotec.com](https://downloads.signotec.com/signoPAD-API_Web/),\n  briefly runs the InstallShield wrapper under Wine to obtain the inner\n  MSI, then unpacks `MSI → Data1.cab → flat binary list`. **No** signotec\n  binaries are committed to this repo — they're fetched directly from\n  the vendor on every build.\n* **Stage 2 (runtime)** — Ubuntu 22.04 Jammy + Wine 32/64 + the\n  extracted binaries. `WINEDLLOVERRIDES` forces Wine to load the native\n  MSVC runtime DLLs that ship with signotec (their Boost.Asio uses\n  `?_Throw_Cpp_error@std`, which is missing from Wine's own `msvcp140`\n  stub).\n\nThe container listens on `0.0.0.0:49494` by default and speaks **plain\nWS** (no TLS — TLS termination is delegated to Apache/Nginx with your\nexisting certificate).\n\n## TLS reverse proxy\n\nExample snippet for an Apache 2 SSL vhost (see\n[`apache/orbit-ssl-signotec.snippet`](apache/orbit-ssl-signotec.snippet)):\n\n```apache\nProxyPass        /signotec-ws/ ws://127.0.0.1:49494/\nProxyPassReverse /signotec-ws/ ws://127.0.0.1:49494/\n```\n\nBrowsers then connect to `wss://\u003chost\u003e/signotec-ws/` — your own TLS\ncertificate, your own origin. Works for multiple hostnames or IPs\nwithout having to reconfigure the pad server.\n\n## Client-side code\n\nThe browser loads signotec's official `STPadServerLib-3.5.0.js` and\nconnects through the TLS endpoint. From a JavaScript perspective the\nresult is identical to a station-PC setup with a USB-attached pad —\nsame API mode, same `Pdf.load` + `Display.setPDF` flow.\n\n## Operations\n\n```bash\ndocker ps --filter name=signotec-stpadserver\njournalctl -u signotec-stpadserver -f\nsudo systemctl restart signotec-stpadserver\n```\n\n## Files\n\n| File                                          | Purpose                                          |\n|-----------------------------------------------|--------------------------------------------------|\n| `Dockerfile`                                  | Multi-stage build: extract installer + runtime   |\n| `wine-entrypoint.sh`                          | Wine prefix init + server start                  |\n| `systemd/signotec-stpadserver.service`        | systemd unit for auto-start                      |\n| `apache/orbit-ssl-signotec.snippet`           | Example reverse-proxy snippet for Apache         |\n| `install.sh`                                  | Full setup script (sudo)                         |\n\n## License / contributors\n\nCode in this repository: MIT, © 2026 Florian Hesse / comnic IT\n(https://comnic-it.de).\n\nThe signotec binaries fetched at build time are property of\n[signotec GmbH](https://www.signotec.com) and are subject to their own\nlicense terms — they are not stored in this repo, but downloaded fresh\nfrom the signotec download portal on every build.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffloppy007%2Fsignotec-stpadserver-bridge","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffloppy007%2Fsignotec-stpadserver-bridge","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffloppy007%2Fsignotec-stpadserver-bridge/lists"}
