SSL & TLS Essentials: Securing the Web Publisher: Wiley Language: English ISBN: 0471383546 Paperback: 224 pages Data: February 11, 2000 Format: PDF Description: "Great writing . . . a clear introduction to the most widely deployed security technology in the Internet."-Paul Lambert, former co-chair of IETF IPSEC working group The Secure Sockets Layer (SSL) and Transport Layer Security(TLS) protocols form the foundation for e-commerce security on the World Wide Web, verifying the authenticity of Web sites, encrypting the transfer of sensitive data, and ensuring the integrity of information exchanged. Now-for the first time the details of these critical security protocols are available in a complete, clear, and concise reference. SSL and TLS Essentials provides complete documentation of the SSL and TLS protocols, including advanced and proprietary extensions never before published. The book thoroughly covers the protocols in operation, including the contents of their messages, message formats, and the cryptographic calculations used to construct them. The text also includes an introduction to cryptography and an explanation of X.509 public key certificates. Stephen Thomas, author of IPng and the TCP/IP Protocols, presents this complex material in a clear and reader-friendly manner. The book includes more than 80 figures and illustrations to supplement its text, and it describes SSL in the context of real-world, practical applications. Readers will immediately understand not only the academic principles behind he security protocols, but how those principles apply to their own network security challenges. The book includes: * Full details of Netscape's SSL and the IETF's TLS protocols, with differences between the two clearl highlighted and explained * A concise tutorial in cryptography * Complete coverage of Netscape's International Step-Up and Microsoft's Server Gated Cryptography implementations * A description of X.509 public key certificates * Details on implementing backwards compatibility among previous versions of SSL and TLS * A thorough security checklist with explanations of all known attacks on SSL implementations, along with appropriate countermeasures.

openssl 库1.1.1o and 3.0.3

openssl lib 3.0.3

mqtt支持ws的mosquitto工具和node测试Demo;该压缩包已包含了所有需要的DLL，上一次资源中缺少部分DLL，mosquitto在一些电脑上不能运行。测试方法：mosquitto -c mosquitto.conf -v，正常开启后会显示websocket 已监听，固定5积分。

STM32c8t6通过ESP8266连接网络，通过烧录mqtt固件，通过at指令连接物联网平台。 内含wifi的连接指令函数与连接mqtt物联网函数，还有数据传输函数，数据传输到阿里云上之后再物模型上面直接显示。

Windows x64 的 Openssl 1.1.1 安装包msi OpenSSL 是一个安全套接字层密码库，囊括主要的密码算法、常用的密钥和证书封装管理功能及SSL协议，并提供丰富的应用程序供测试或其它目的使用。 OpenSSL被曝出现严重安全漏洞后，发现多数通过SSL协议加密的网站使用名为OpenSSL的开源软件包。OpenSSL漏洞不仅影响以https开头的网站，黑客还可利用此漏洞直接对个人电脑发起"心脏出血"(Heartbleed)攻击。据分析，Windows上有大量软件使用了存在漏洞的OpenSSL代码库，可能被黑客攻击抓取用户电脑上的内存数据。

mqtt5.0中文版文档 MQTT v5.0添加了以下特性 会话过期 把清理会话标志拆分成新开始标志（指示会话应该在不使用现有会话的情况下开始）和会话过期间隔标志（指示连接断开之后会话保留的时间）。会话过期间隔时间可以在断开时修改。把新开始标志设置为1且会话过期间隔标志设置为0，等同于在MQTT v3.1.1中把清理会话（CleanSession）设置为1。
