Hey Product Hunt! šŸ‘‹ We're the team behind Trexo PDF Signer, and we're really excited to share it with this community today. The idea came from a frustration we kept running into ā€” most PDF signing tools either cost a fortune, require you to upload sensitive documents to the cloud, or simply don't support hardware security tokens like USB dongles and smart cards. For professionals in legal, finance, and government sectors where document security isn't optional, that's a real problem. So we built Trexo PDF Signer: a completely free, open-source desktop app that handles real cryptographic signing the way enterprises actually need it ā€” with PKCS#11 hardware tokens, PFX certificate files, Windows Certificate Store, RFC 3161 trusted timestamps, and full Adobe Acrobat compatibility. Everything runs locally on your machine. No cloud. No subscription. No data leaving your hands. We'd love to hear from you: ā€” Do you deal with PDF signing in your workflow? ā€” Are there specific hardware tokens or certificate types you need supported? ā€” What features would make this a must-have tool for your team? All feedback is welcome ā€” we're actively developing and the roadmap is wide open. And if you find it useful, a star on GitHub means the world to a small open-source team. šŸ™ Thanks for checking us out!
