Encryption algorithm behind SSL certificate (HTTPS)Before we introduced how SSL works, we learned that when you enter the URL at the beginning of HTTPS in the address bar of the browser, there will be a lot of communication between the browser and the server within the next hundreds of milliseconds. The first step in these complex steps is to negotiate a key algorithm that is used in subsequent communicatio
in the development of the Java version of the Mosquitto client program needs to use the PAHO library, if the development of Java client to use the SSL function, you need to bouncy Castle library, when using the SSL function, the certificate file is required for authentication, However, during the testing process, you only make your own CA and issue the certificate. During testing, you first create a unifie
As we all know, network data transmission between different hosts is mainly completed through the TCP/IP network protocol. This is true for enterprise LAN data transmission and Internet data transmission. However, it is hard to figure out that no security was provided during the design of the TCP/IP protocol. That is to say, the TCP/IP protocol alone cannot guarantee the secure and stable transmission of data in the network. Therefore, the security of data in the network depends on high-level ap
To clarify the implementation principle of the HTTPS protocol, at least the following background knowledge is required. Get a general idea of the meaning of several basic terms (HTTPS, SSL, TLS) Get an overview of the relationship between HTTP and TCP (especially "short connections" VS "long Connections") A general understanding of the concept of cryptographic algorithms (especially the difference between symmetric and asymmetric encr

Secure Sockets Layer, or SSL, is a standard security technique for encrypting connections between Web sites and browsers. This ensures that the data transferred between the server and the browser remains private and secure. It is used by thousands of people to protect their communications with customers. To enable SSL linking, the Web server requires an SSL certi
Recently to do an SSL application, two-way authentication with SSL means that when the client connects to the server, both sides of the link have to authenticate each other's digital certificate to ensure that it is authorized to be able to connect. When we link general SSL with one-way authentication, the client only validates the server's certificate, the serve
