FireDaemon OpenSSL

OpenSSL is a popular open-source software library and command-line tool that provides a robust, full-featured set of cryptographic functions to secure communications over computer networks. It implements the Transport Layer Security (TLS) protocol, which is used to encrypt data transmissions across a wide range of applications including web servers, email, VPNs, databases, and IoT devices. OpenSSL provides a wide range of cryptographic functions, including symmetric encryption, public-key encryption, message digest and hash functions, digital signatures, and random number generation. It supports a large number of cryptographic algorithms, including AES, RSA, ECDSA, and Diffie-Hellman, as well as post-quantum algorithms such as ML-KEM, ML-DSA, and SLH-DSA. In addition to cryptographic functions, OpenSSL provides utilities for generating and managing digital certificates and keys, creating and verifying digital signatures, and performing TLS handshakes and negotiations. It also includes a comprehensive command-line tool for certificate management, key generation, TLS diagnostics, and general cryptographic operations.

​When we build and ship FireDaemon Certify One, FireDaemon Fusion, and FireDaemon Lozenge we try to ensure they contain the most recent version of OpenSSL. We thought it would be useful to make our OpenSSL Binary Distributions (in EXE installer and ZIP file formats) available to you to download and use free of charge.

 

The key advantages of using FireDaemon OpenSSL over others that are available are:

​

• Recognised Trusted Source: Officially listed by the OpenSSL Project as a trusted third-party binary distribution for Windows; one of a handful of providers to carry that designation.

• Zero Dependencies: No Microsoft Visual C++ Redistributables required. Builds link against the native Windows Universal C Runtime (UCRT) for clean-system stability across modern Windows environments.

• FIPS 140-3 Support: Ships with the OpenSSL FIPS Provider, enabling FIPS 140-3 validated cryptographic operations for workloads subject to federal, government, or regulated-industry compliance requirements. The FIPS provider can be enabled independently of the standard provider, giving you surgical control over cryptographic policy.

• EV-Signed Integrity: All installers and binaries are digitally signed with a Sectigo Extended Validation (EV) certificate, guaranteeing authenticity and eliminating Windows SmartScreen friction at deployment.

• Flexible Deployment: Packaged for standalone, portable, or embedded use cases; drop it into an existing toolchain, bundle it with your application, or run it from removable media without system-level installation.

• Verifiable Security: Every build is pre-scanned via VirusTotal prior to release, and our build scripts are publicly available for independent verification. No black-box binaries, no trust-me security.

• Audit-Ready Compliance: Built for developers and sysadmins who need a documented, reproducible, and inspectable OpenSSL environment; whether for internal audit, customer assurance, TPN/MPA, or regulated-sector procurement requirements.
