Some people have offered to provide OpenSSL binary distributions for selected operating systems. The condition to get a link here is that the link is stable and can provide continued support for OpenSSL for a while.

Note: many Linux distributions come with pre-compiled OpenSSL packages. Those are already well-known among the users of said distributions, and will therefore not be mentioned here. If you are such a user, we ask you to get in touch with your distributor first. This service is primarily for operating systems where there are no pre-compiled OpenSSL packages.

OpenSSL 1.1.1i — криптографическая библиотека с кодом открытого типа «Open source». Она предназначена для работы с протоколами SSL и TLS, а также доступна для платформ Windows и Unix.

Основные возможности

  1. Поддержка практически всех алгоритмов хеширования, шифрования и электронной подписи.
  2. Реализация большинства криптографических стандартов.
  3. Работа с ключами (RSA, DH, DSA) и сертификатами.
  4. Поддержка сертификатов X.509.
  5. Формирование приватных ключей CRT и CSR.
  6. Тестирование соединений: SSL и TLS.

Удобство использования

Библиотеку используют все разработчики WEB-приложений, поскольку она отвечает за безопасность. При создании сайта обязательно необходимо создавать SSL-ключ (файл, позволяющий связать криптографический ключ с доменным именем или сервером). Библиотеку можно использовать для тестирования соединений SSL и TTL.

Специальных приложений для работы с библиотекой в графическом интерфейсе не существует. В этом случае приходится довольствоваться только консольным режимом, в котором требуется вводить команды.

Для новичка, на первый взгляд, покажется все очень сложным, но на самом деле это не так. Для работы с библиотекой в Интернете можно найти множество инструкций и видеоуроков, в которых детально объясняются основные аспекты ее использования.

«Изюминка» библиотеки заключается в открытом коде, в который можно вносить изменения, переписывать и удалять ненужные функции, т. е. создавать свой собственный модуль.

Разработчики рекомендуют скачивать ее с официального сайта. Однако не стоит забывать и о «GitHub» (хранилище, которое IT-специалисты используют для обмена программным кодом).

Достоинства

  • Поддержка алгоритмов шифрования, хеширования.
  • Работа с сертификатами и электронной подписью.
  • Тестирование SSL/TTL-соединений.
  • Гибкая настройка параметров создаваемых сертификатов.
  • Поддержка CRT и CSR, а также сертификата X.509.
  • Работа с ключами RSA, DH и DSA.
  • Бесплатная версия.
  • Открытый код (можно вносить свои коррективы в исходный программный код библиотеки).
  • Высокая степень надежности.
  • Реализация всех типов криптографических стандартов.

Недостатки

  • Отсутствие графического интерфейса.
  • Сложный синтаксис команд для новичков.

Библиотека является неотъемлемой частью каждого WEB-приложения и напрямую связана с его безопасностью. Благодаря открытому коду, ее можно изменить и доработать под свои предпочтения.

В эпоху кибервойн единственная разумная позиция – быть параноиком, а это означает, помимо прочего, быть параноиком по поводу обновлений программного обеспечения.

Взять к примеру OpenSSL.

Эта криптографическая библиотека с открытым исходным кодом, которая реализует протоколы Transport Layer Security (TLS) и Secure Sockets Layer (SSL), разработана для «защиты связи по компьютерным сетям от перехвата», но угадайте, что?

С самого начала она была пронизана ошибками.

Это может быть неизбежно, в определенной степени – в конце концов, мы говорим о программном обеспечении.

Несмотря на то, что вы не можете ничего сделать с ошибками, которые еще предстоит идентифицировать, вы можете по крайней мере защитить свои системы от тех ошибок, которые уже исправлены и задокументированы.

Жаль, что официальный сайт OpenSSL предлагает только исходники для Linux.

Хотя дистрибутивы Linux обычно поставляются с OpenSSL, это не никак относится к Windows … или, скажем, «дистрибутивам Windows».

Если вы хотите запустить его, вам нужен бинарник под Windows, и если вы не хотите его собирать самостоятельно, вы должны найти другой вариант.

В этой статье я покажу,как можно настроить OpenSSL в Windows, не имея дело при этом дела со сборкой из исходников.

Содержание

  1. Шаг 1. Скачать бинарник
  2. Шаг 2. Запустите установщик
  3. Шаг 3. Запустите бинарный файл OpenSSL

Шаг 1. Скачать бинарник

Поиск бинарных файлов OpenSSL для Windows – непростая задача, но не отчаивайтесь.

Они существуют.

Чтобы загрузить нужный, перейдите по ссылке:

https://slproweb.com/products/Win32OpenSSL.html

Не дайте себя одурачить ни строкой Win32 в URL-адресе, ни навигацией, указывающей на казалось бы древнюю страницу загрузки еще с 2004 года.

Прокрутите страницу вниз до раздела «Download Win32 OpenSSL».

Теперь вам нужно выбрать правильный файл из этого списка.

Для каждой версии есть два основных типа: light и full.

Загрузите файл под названием «Win64 OpenSSL v1.1.0f» (или версию с более новой версией, как только она станет доступна), чтобы скачать фулл установщик.

Текущая версия на момент написания этой статьи (OpenSSL 1.1.0h) сильно отличается от предыдущих версий.

Это совсем не одно и то же, поэтому обратите внимание на номера релизов!

Худшее, что вы можете сделать, – это использовать старую версию, в которой есть задокументированные ошибки.

Шаг 2. Запустите установщик

Мы рекомендуем установить OpenSSL вне вашей системной директории Windows.

Следуйте инструкциям по установке через GUI.

Шаг 3. Запустите бинарный файл OpenSSL

Чтобы начать работу с OpenSSL, вы можете просто щелкнуть по нему правой кнопкой мыши в проводнике Windows в месте его установки, например в моем случае:

C:\OpenSSL-Win64\bin\

затем выберите «Запуск от имени администратора».

Откроется окно cmd с командной строкой OpenSSL:

Теперь вы можете начать создавать ключи OpenSSL. (Кстати, пользователи утилиты удаленного доступа PuTTY могут экспортировать ключ OpenSSH из PuTTYgen.)

При использовании OpenSSL в Windows таким способом вы просто пропускаете команду openssl, которую видите в приглашении.

Например, чтобы создать пару ключей с помощью OpenSSL в Windows, вы можете ввести:

openssl req -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem

и следуйте инструкциям на экране, как обычно.

Чтобы просмотреть сертификат:

openssl x509 -text -noout -in certificate.pem

OpenSSL is a robust, commercial-grade, full-featured Open Source Toolkit
for the Transport Layer Security (TLS) protocol formerly known as the
Secure Sockets Layer (SSL) protocol. The protocol implementation is based
on a full-strength general purpose cryptographic library, which can also
be used stand-alone.

OpenSSL is descended from the SSLeay library developed by Eric A. Young
and Tim J. Hudson.

The official Home Page of the OpenSSL Project is www.openssl.org.

Overview

The OpenSSL toolkit includes:

  • libssl
    an implementation of all TLS protocol versions up to TLSv1.3 (RFC 8446).

  • libcrypto
    a full-strength general purpose cryptographic library. It constitutes the
    basis of the TLS implementation, but can also be used independently.

  • openssl
    the OpenSSL command line tool, a swiss army knife for cryptographic tasks,
    testing and analyzing. It can be used for

    • creation of key parameters
    • creation of X.509 certificates, CSRs and CRLs
    • calculation of message digests
    • encryption and decryption
    • SSL/TLS client and server tests
    • handling of S/MIME signed or encrypted mail
    • and more…

Download

For Production Use

Source code tarballs of the official releases can be downloaded from
www.openssl.org/source.
The OpenSSL project does not distribute the toolkit in binary form.

However, for a large variety of operating systems precompiled versions
of the OpenSSL toolkit are available. In particular, on Linux and other
Unix operating systems, it is normally recommended to link against the
precompiled shared libraries provided by the distributor or vendor.

For Testing and Development

Although testing and development could in theory also be done using
the source tarballs, having a local copy of the git repository with
the entire project history gives you much more insight into the
code base.

The official OpenSSL Git Repository is located at git.openssl.org.
There is a GitHub mirror of the repository at github.com/openssl/openssl,
which is updated automatically from the former on every commit.

A local copy of the Git Repository can be obtained by cloning it from
the original OpenSSL repository using

git clone git://git.openssl.org/openssl.git

or from the GitHub mirror using

git clone https://github.com/openssl/openssl.git

If you intend to contribute to OpenSSL, either to fix bugs or contribute
new features, you need to fork the OpenSSL repository openssl/openssl on
GitHub and clone your public fork instead.

git clone https://github.com/yourname/openssl.git

This is necessary because all development of OpenSSL nowadays is done via
GitHub pull requests. For more details, see Contributing.

Build and Install

After obtaining the Source, have a look at the INSTALL file for
detailed instructions about building and installing OpenSSL. For some
platforms, the installation instructions are amended by a platform specific
document.

  • Notes for UNIX-like platforms
  • Notes for Android platforms
  • Notes for Windows platforms
  • Notes for the DOS platform with DJGPP

About OpenSSL

OpenSSL is a popular open-source, publicly available software library that provides a robust, full-featured set of cryptographic functions and tools to secure communications over computer networks. When we build and ship FireDaemon Certify One, FireDaemon Fusion, and FireDaemon Lozenge we try to ensure it contains the most recent version of OpenSSL. We thought it would be useful to make our OpenSSL Binary Distribution available to you to download and use free of charge. The key advantages of using our OpenSSL Binary Distribution for Microsoft Windows over others that are available are:

  • No need to deploy various software tools in order to attempt to compile the source from scratch. Our build script is available for free too if you do want to compile OpenSSL yourself.
  • No external dependencies. There is no need to install or distribute the Visual C++ Redistributable Runtime (MSVC). There is an implicit dependency on the Windows Universal C Runtime (UCRT) which is included by default in all modern versions of Microsoft Windows.
  • Packaged for simple deployment and use case scenarios including standalone, embeddable, deployable, or portable
  • Digitally signed with our Extended Validation (EV) code signing certificate in order to avoid Windows SmartScreen warnings, and increase trust by virtue of Sectigo’s authentication and verification procedures on us: FireDaemon Technologies Limited and validatable binary integrity to meet your compliance requirements.

Download OpenSSL

Pre-compiled executables (EXE) and libraries (DLL) for Microsoft Windows Operating Systems. The distributions can be used standalone or integrated into any Windows application. The EXE and DLL are digitally signed with our Extended Validation (EV) code signing certificate. Note that we do not have an EAR CCL ECCN for our Binary Distributions. This is intentional. You must seek independent legal advice prior to using/integrating/exporting our Binary Distributions in your own products.

Installation Instructions

OpenSSL ZIP Files

  1. Follow the instructions below if you have downloaded one of the ZIP files above and want to deploy OpenSSL manually (e.g. on the local hard disk or on a USB drive for a portable installation)
  2. Download the appropriate FireDaemon OpenSSL Binary Distribution ZIP file via the links above.
  3. Unpack the contents of the «openssl-1.1» or «openssl-3» or «openssl-3.1.0» folder in the respective ZIP file to a temporary directory (e.g. C:\Temp)
  4. Copy the contents of (i.e. the files and directories contained within) the x64 folder or x86 folder to your target directory (e.g. C:\OpenSSL)
  5. Copy the ssl folder and contents to the target directory (e.g. C:\OpenSSL).

The commands to copy the files correctly from the location where you unpacked the ZIP file (assuming C:\Temp) are as follows:

: For OpenSSL 1.1
cd C:\Temp\openssl-1.1

: For OpenSSL 3.0 and 3.1
cd C:\Temp\openssl-3

: Copy the binaries specific to your platform
: Copy 64-bit binaries
robocopy x64 C:\OpenSSL /E

: Or, copy 32-bit binaries. Don't copy both!
robocopy x86 C:\OpenSSL /E

: Copy the ssl folder
robocopy ssl C:\OpenSSL\ssl /E

Your directory structure should look as follows:

C:\OpenSSL>dir /b
bin
include
lib
ssl

To use OpenSSL, simply open an elevated Command Prompt then (adjusting the path in OPENSSL_HOME to suit your manual installation):

: You can set OPENSSL_HOME=%~dp0 in a batch script for portable installs
set OPENSSL_HOME=C:\OpenSSL
set OPENSSL_CONF=%OPENSSL_HOME%\ssl\openssl.cnf
set PATH=%OPENSSL_HOME%\bin;%PATH%
cd /d %OPENSSL_HOME%
openssl version -a

To create a certificate signing request and private key using the same environment variables as above :

openssl genrsa -out server.key 4096
openssl req -new -key server.key -out server.csr -sha256
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

OpenSSL Windows Installer

Instead of downloading the ZIP file, and for convenience, you can download our Windows installer via the link above in the «Download OpenSSL» section. Installation is straightforward. OpenSSL is installed into the following file system locations. These locations are specified during the build and follow OpenSSL’s own conventions. Thanks to Advanced Installer for helping us out.

%PROGRAMFILES%\FireDaemon OpenSSL 3
%PROGRAMFILES%\Common Files\FireDaemon SSL 3

You can silently install OpenSSL with the following command in an elevated command prompt:

FireDaemon-OpenSSL-x64-3.1.3.exe /exenoui /exelog fdopenssl3.log /qn /norestart REBOOT=ReallySuppress

You can silently uninstall OpenSSL with the following command in an elevated command prompt:

: Verify Product GUID
wmic product where name="FireDaemon OpenSSL 3" get IdentifyingNumber
: Uninstall silently
msiexec /x {A8B0D50D-F952-49EB-A53A-BDB95BA32284} /quiet /noreboot

Compiling OpenSSL From Source

Release Policy

Whenever we release an updated version of FireDaemon Fusion, FireDaemon Certify One, or OpenSSL gets updated with security fixes, we will provide the latest tagged version of the OpenSSL stable branch. The currently deployed OpenSSL library commit versions are listed underneath the download links above. Commit is described viz:

git describe --always --tag --long --first-parent --dirty

Source

We directly pull from OpenSSL’s official GitHub repository.

Build Script

You can use our build script to create the binary distributions. The build script has the following dependencies:

  • Visual Studio Community Edition
  • Git for Windows
  • Strawberry Perl.

Compilation

The actual command line to build OpenSSL is as follows (where %toolset% is VC-WIN32 and VC-WIN64A respectively):

perl ..\Configure %toolset% no-asm no-ssl3 no-zlib no-comp no-autoload-config --api=1.1.0 --prefix="%installdir%" --openssldir="%commoninstalldir%" -DOPENSSL_NO_DEPRECATED

Integrating OpenSSL with Your Visual Studio Project

To use the headers and libraries present in OpenSSL in your Visual Studio project, you will need to configure the properties of your project.

Additional Include Directories

Visual Studio Project Property Pages Additional Library Directories

Privilege Escalation Mitigation

When building OpenSSL, the build scripts bake the default location of the library (ie. the installation directory) and the SSL configuration into the final product. By default, OpenSSL automatically loads the SSL configuration file from the default file system location. This leads to an easily exploitable privilege escalation scenario documented in CVE-2019-12572. Our build of OpenSSL mitigates this flaw using the following preventative measures:

  • The target directories we have chosen are Windows’ default system program files directories assuming a 64-bit architecture with a shared configuration file directory common to both x64 and x86:
    • x64: C:\Program Files\FireDaemon OpenSSL, C:\Program Files\Common Files\FireDaemon SSL
    • x86: C:\Program Files (x86)\FireDaemon OpenSSL, C:\Program Files\Common Files\FireDaemon SSL
  • To mitigate security holes even on non-default installations, we build the library such that it doesn’t automatically load the SSL configuration. Hence, when using the OpenSSL tools or the DLLs in your products you have to explicitly load the SSL configuration.
  • All FireDaemon software products that utilise OpenSSL initialise the OpenSSL library at runtime using a flag that prevents the loading of the default configuration.
