OpenSSL 1.1.0k / 1.0.2s для Windows x64/x32
Информация о программе
Описание
OpenSSL – библиотека криптографических алгоритмов с открытым исходным кодом. Она получила распространение благодаря протоколу HTTPS, который использует шифрование SSL и TSL.
Библиотека по большей части написана на низкоуровневом языке программирования C. OpenSSL используется на UNIX и UNIX-like операционных системах: Linux, Solaris, macOS, QNX, BSD, а также ОС семейства Windows. Поддерживаемые аппаратные платформы: x32, x64, ARM и др.
В OpenSSL реализованы как симметричные, так и ассиметричные алгоритмы шифрования. Симметричные алгоритмы подразумевают, что используется один ключ для шифрования и дешифрования. В ассиметричных алгоритмах есть понятие открытого ключа (он передается по открытому каналу), который используется для проверки электронной подписи. Для подписания документов автором используется закрытый ключ.
Также в библиотеке OpenSSL предусмотрены Хеш-функции. Эти алгоритмы преобразуют данные различного размера в строку одинаковой длины по заданным алгоритмам. Такие действия применяются для хранения паролей в базах данных. Чтобы надежнее защитить данные, к паролю добавляется «соль». Таким образом, злоумышленники, имея таблицу хеш-сумм и зная алгоритм хеширования, не смогут получить изначальный пароль без криптографической соли.
Функции и особенности библиотеки OpenSSL для Windows:
- Поддержка основных алгоритмов шифрования и хеширования;
- Бесплатное распространение для коммерческого использования;
- Широкое распространение среди пользователей, благодаря чему быстро обнаруживаются и исправляются уязвимости;
- Применение в различных сферах: от ЭП до проверки корректности скачанного файла.

Downloads
The master sources are maintained in our git repository, which is accessible over the network and cloned on GitHub, at https://github.com/openssl/openssl. Bugs and pull patches (issues and pull requests) should be filed on the GitHub repo. Please familiarize yourself with the license.
The table below lists the latest releases for every branch. (For an explanation of the numbering, see our release strategy.) All releases can be found at /source/old. A list of mirror sites can be found here.
Note: The latest stable version is the 1.1.1 series. This is also our Long Term Support (LTS) version, supported until 11th September 2023. All older versions (including 1.1.0, 1.0.2, 1.0.0 and 0.9.8) are now out of support and should not be used. Users of these older versions are encourage to upgrade to 1.1.1 as soon as possible. Extended support for 1.0.2 to gain access to security fixes for that version is available.
The OpenSSL FIPS Object Module 2.0 (FOM) is also available for download. It is no longer receiving updates. It must be used in conjunction with a FIPS capable version of OpenSSL (1.0.2 series). A new FIPS module is currently in development.
OpenSSL 3.0 is the next major version of OpenSSL that is currently in development and includes the new FIPS Object Module. A pre-release version of this is available below. This is for testing only. It should not be used in production. Information and notes about OpenSSL 3.0 are available on the OpenSSL Wiki

When building a release for the first time, please make sure to look at the INSTALL file in the distribution along with any NOTES file applicable to your platform. If you have problems, look at the FAQ, which can be found online. If you still need more help, then join the openssl-users email list and post a question there.
PGP keys for the signatures are available from the OMC page. Current members that sign releases include Richard Levitte and Matt Caswell.
Each day we make a snapshot of each development branch. They can be found at https://www.openssl.org/source/snapshot/. These daily snapshots of the source tree are provided for convenience only and not even guaranteed to compile. Note that keeping a git local repository and updating it every 24 hours is equivalent and will often be faster and more efficient.
Legalities
Please remember that export/import and/or use of strong cryptography software, providing cryptography hooks, or even just communicating technical details about cryptography software is illegal in some parts of the world. So when you import this package to your country, re-distribute it from there or even just email technical suggestions or even source patches to the authors or other people you are strongly advised to pay close attention to any laws or regulations which apply to you. The authors of OpenSSL are not liable for any violations you make here. So be careful, it is your responsibility.
