DESCRIPTION
-----------
The OpenSSL Project is a collaborative effort to develop a robust,
commercial-grade, fully featured, and Open Source toolkit implementing the
Transport Layer Security (TLS) protocols (including SSLv3) as well as a
full-strength general purpose cryptographic library.
OpenSSL is descended from the SSLeay library developed by Eric A. Young
and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the
OpenSSL license plus the SSLeay license), which means that you are free to
get and use it for commercial and non-commercial purposes as long as you
fulfill the conditions of both licenses.
OVERVIEW
--------
The OpenSSL toolkit includes:
libssl (with platform specific naming):
Provides the client and server-side implementations for SSLv3 and TLS.
libcrypto (with platform specific naming):
Provides general cryptographic and X.509 support needed by SSL/TLS but
not logically part of it.
openssl:
A command line tool that 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...
INSTALLATION
------------

SUPPORT
-------
See the OpenSSL website www.openssl.org for details on how to obtain
commercial technical support. Free community support is available through the
openssl-users email list (see
https://www.openssl.org/community/mailinglists.html for further details).
If you have any problems with OpenSSL then please take the following steps
first:
- Download the latest version from the repository
to see if the problem has already been addressed
- Configure with no-asm
- Remove compiler optimization flags
If you wish to report a bug then please include the following information
and create an issue on GitHub:
- OpenSSL version: output of 'openssl version -a'
- Configuration data: output of 'perl configdata.pm --dump'
- OS Name, Version, Hardware platform
- Compiler Details (name, version)
- Application Details (name, version)
- Problem Description (steps that will reproduce the problem, if known)
- Stack Traceback (if the application dumps core)
Just because something doesn't work the way you expect does not mean it
is necessarily a bug in OpenSSL. Use the openssl-users email list for this type
of query.

LEGALITIES
----------
A number of nations restrict the use or export of cryptography. If you
are potentially subject to such restrictions you should seek competent
professional legal advice before attempting to develop or distribute
cryptographic code.

《Win64 OpenSSL-Light-1-1-1d.exe:64位系统下的轻量级QTSSL库解析》
在IT行业中,安全通信是至关重要的,而这离不开SSL(Secure Socket Layer)及其升级版TLS(Transport Layer Security)协议的支持。当我们谈论"Win64 OpenSSL-Light-1-1-1d.exe"时,我们实际上是在讨论64位Windows系统上使用的OpenSSL库的一个轻量级版本。这个特定的版本,1.1.1d,是在2019年发布,为开发者和用户提供了一套强大的安全工具。
OpenSSL是一个开源的库,包含了实现SSLv2/v3以及TLSv1/tls1.1/tls1.2/tls1.3协议所需的加密算法、证书处理以及相关的实用工具。它广泛应用于Web服务器,确保了用户与服务器之间的数据传输安全,如HTTPS协议就是基于SSL/TLS的。"Light"版本意味着它只包含核心功能,相对于"Full"版本,它不包括一些开发和测试工具,因此体积更小,适合那些只需要基本加密功能的场合。
QTSSL库,标签中提到的关键词,通常是指Qt框架中的SSL支持模块。Qt是一个跨平台的应用程序开发框架,广泛用于创建图形用户界面和各种应用程序。QTSSL库是Qt与OpenSSL的集成,使得Qt应用程序能够利用OpenSSL提供的加密服务,例如进行安全的网络连接,进行证书验证等。
"Win64OpenSSL-Light-1-1-1d.exe"的安装将为Windows 64位系统提供必要的SSL库,使得开发者在构建QTSSL应用时可以轻松地集成OpenSSL的功能。这个版本修复了一些已知的安全漏洞,并提供了对最新加密标准的支持,提高了系统的安全性。同时,由于它是轻量级的,不会对系统资源造成过大的负担,适合于那些对性能有较高要求的环境。
在实际应用中,用户或开发者需要注意以下几点:
1. 安装后,开发者需要在Qt项目中配置SSL支持,引用OpenSSL库。
2. 使用SSL/TLS时,应确保正确处理证书验证,防止中间人攻击。
3. 及时更新OpenSSL库,以应对不断出现的新安全威胁。
4. 对于个人用户,安装此库可以提升浏览器或其他依赖SSL的软件的安全性。
"Win64 OpenSSL-Light-1-1-1d.exe"是64位Windows系统上一个轻便且强大的SSL解决方案,对于开发者和用户而言,它提供了安全的网络通信基础,确保了数据的私密性和完整性。理解其功能和使用方法,对于维护网络安全至关重要。
