Implement the Secure Sockets Layer and Transport Layer Security cryptographic protocols. Access an extensive library and work with a wide range of encryption algorithms, including Blowfish, MD5, SHA-1, DES, AES, RSA, DSA, and the Diffie–Hellman key exchange method.

Download of OpenSSL 3.0.5 was on the developer's website when we last checked. We cannot confirm if there is a free download of this software available. This free software is a product of OpenSSL Team. The software is included in Development Tools.

The most popular versions of the tool are 1.1, 1.0 and 0.9. This free PC software was developed to work on Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10 or Windows 11 and can function on 32 or 64-bit systems. We recommend checking the downloaded files with any free antivirus. Cmd.exe, iexplore.exe, openssl.exe and unins000.exe are the most common filenames for this program's installer.

From the developer:

The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library.
