FireDaemon OpenSSL for Microsoft Windows

Professional, EV-Signed, and Dependency-Free Binaries for Enterprise

Below you will find our pre-compiled OpenSSL executables and libraries for Microsoft Windows operating systems packaged as EXE installers and ZIP files. FireDaemon OpenSSL can be used standalone or integrated into any Windows application. Enterprise deployment requires more than just a binary. FireDaemon OpenSSL is a trusted, hardened distribution engineered for reliability, security, and zero-touch automation.

​​

  • Recognised Source: Listed by the OpenSSL Project as a trusted third-party binary distribution for Windows.

  • Zero Dependencies: No Microsoft Visual C++ Redistributables required. We leverage the native Windows Universal C Runtime (UCRT) for "clean system" stability.

  • EV-Signed Integrity: All installers and binaries are digitally signed with a Sectigo Extended Validation (EV) certificate to ensure authenticity and bypass Windows SmartScreen warnings.

  • Flexible Deployment: Packaged for standalone, portable, or embedded use cases.

  • Verifiable Security: Every build is pre-scanned via VirusTotal and backed by our publicly available build scripts for total transparency.

  • Compliance Ready: Designed for developers and sysadmins who require a verifiable, audit-ready OpenSSL environment.
