ATick signs PDFs the way Adobe Acrobat and the EU DSS do — **PAdES baseline** signatures with timestamps and long-term validation. The matching engine for your platform ships **inside the package** and is loaded automatically through PHP **FFI** — there is **no external service**, **nothing to compile**, and **no PHP dependencies**. Run `composer require aniketc068/atick` and you are done.
