Announcing the OpenSSL Library Installer for Windows (Testing Release)

A testing release of the OpenSSL Library installer for Microsoft Windows is now available. This is the first officially produced binary distribution of the OpenSSL Library.

Until now, the OpenSSL Library has been distributed in source form only. Windows users have had to build the library themselves or rely on binary packages produced by third parties. The new installer provides a distribution channel directly from us: binaries built, packaged, and signed by the OpenSSL Corporation.

The installer provides:

- the OpenSSL Library DLLs,

- the `openssl.exe` command-line application, and

- the development kit for building applications against the OpenSSL Library.

The installer, the application, and all installed DLL files are digitally signed with the OpenSSL Corporation key, so the authenticity and integrity of every component can be verified through the standard Windows code-signing mechanisms.

The minimum supported platforms are Windows 7 and Windows Server 2008 R2.

The testing installer for OpenSSL Library version 4.0.1 is available at:

Please see the README for installation details and current limitations:

This is a testing release, and we want it exercised across the full range of supported Windows versions and configurations before the stable version ships. Please report any issues through the [openssl/installer issue tracker](https://github.com/openssl/installer/issues) — reports on installation behavior, packaging, signing, and integration with existing toolchains are all valuable, as is any other feedback.

The stable version of the installer will ship starting with the 4.1 release of the OpenSSL Library.
