tls handshake

Some of the security techniques mentioned above, such as message digest, encryption and decryption algorithm, digital signature and data certificate, are not used directly by the developers, but have been encapsulated and even formed some security protocols, exposing certain interfaces for developers to use. Because of the direct use of these security tools, the cost of learning to developers is too high, need to understand the bottom line implementation, and directly use the interface exposed a

We use the TLS secret key approach.Steps:First Part: First generate the secret key on the Docker host and save it to the designated place;Part II: On the Management node (portainer), specify the above secret key and add the node.Specific implementation process:The first part of the code is as followsRead-s PASSWORD//define a passw

Openssl is an open-source implementation of SSL (applications can be downloaded for free). It is a secure and confidential program that is mainly used to improve the security of remote login access. It is also one of the tools currently used in encryption algorithms and has powerful functions.Openssl provides a security protocol for network communication security and data integrity, including key algorithms, common key and certificate encapsulation management functions (CA), and SSL protocols, i

What is the industrial Internet of things?In short, it is the specific application of the Internet of things in industrial control.What is SSL/TLS?SSL (secure Sockets layer Secure socket), and its successor Transport Layer Security (Transport layer Security,tls) is a security protocol that provides security and data integrity for network traffic. TLS encrypts the

SSL is the abbreviation for foreign language "secure Sockets layer", which is called "Secure Sockets Layer" in Chinese.It was designed by Netscape in the middle of the 90 century. (Incidentally, Netscape not only invented SSL, but also invented a lot of Web infrastructure-such as "CSS stylesheets" and "JS scripts").Why to invent SSL this protocol pinch? Because the HTTP protocol used on the internet is plaintext, there are a number of drawbacks-such as the fact that the transmitted content is pe

HTTPS joins the SSL protocol based on HTTP, which relies on certificates to verify the identity of the server and encrypt communication between the browser and the server. Specifically how to encrypt, decrypt, verify, and see, the following is called a handshake.1. Client initiates HTTPS request2. Configuration of the server sideServers that use the HTTPS protocol must have a digital certificate, either their own production or CA certificates. The dif

Note: There is no explicit correspondence between active, passive and server, client. This figure n many people know that it helps to troubleshoot and locate network or system failures, but how do you keep this picture in mind? Then you must have a deep understanding of each state of the graph and the process of conversion, and not just stay in the smattering. Below is a detailed analysis of the 11 states of this graph in order to enhance the memory! But before that, let's review the three

Thread Local variable introduction can solve the problem of non-synchronization of static or global variables modified by multiple threads. For a simple example, a function FN may need to modify a static variable. The intention of writing this function is to call the function in its own thread, but if other threads may call this function, the value of this static variable may be damaged. Use local variables of the thread to ensure that each thread uses its own copy and does not interfere with ea

Thread Local Storage (TLS) enables multiple threads of the same process to use an index allocated byTlsallocFunction to store and retrieve a value that is local to the thread. in this example, an index is allocated when the process starts. when each thread starts, it allocates a block of dynamic memory and stores a pointer to this memory in the TLS slot usingTlssetvalueFunction.
