First, what is SSL? The Secure Sockets (SSL) protocol is a protocol that securely exchanges information between a Web Browser and a Web server. SSL is between the application layer and the TCP layer, the application layer data is no longer passed directly to the transport layer, but to the SSL layer,SSL layer to encrypt the data received from the application layer and add its own SSL head. History:1994 , Netscape Company designed the 1.0 version of the SSL protocol (Secure Sockets Layer), but it

handshake process for SSL protocolTo facilitate a better understanding and understanding of the SSL protocol, this article focuses on the SSL protocol Handshake protocol. The SSL protocol uses both public-key cryptography (asymmetric encryption) and symmetric encryption technology, and SSL encrypts the transmitted content with symmetric encryption, and then uses the public key to encrypt the symmetric encry

Socket principleSocket support on-line point-to-point communicationService, the end of the service to realize the listening connection. The client implements the send connection request, and sends and receives data after the connection is established.Server-side build a serversocket. Set the I

A way for Mac to solve the Net/http:tls handshake timeout Docker pull Edit history: 2018.3.14 Larabee Document initialization Reason: Docker default mirror Pull address for foreign warehouse download speed is slower, will be the error "Net/http:tls handshake timeout." At this point, you simply need to change the pull address to a domestic mirrored warehouse. Solution: The first method: for permanent

Recently, there is a business of communication mode for HTTPS two-way authentication, and then very adept to generate the HTTPS certificate, and then fell into the pit.

Last time I talked about the nmake command of ms to compile multiple cpp files. This time, I want to step by step without the help of makefile. Pay attention to the following points: 1. # The mechanism of the include command is to copy the content in the. h file to the. cpp file, so you only need to compile the cpp file. The H file is just a foil. Note that the

An error occurs when running a C ++ program in vs2010: As soon as I see this, my head is big.

To understand why TCP requires a three-way handshake (vernacular), first of all, let's briefly introduce TCP three-way handshake www.2cto.com. In TCP/IP, TCP provides reliable connection services and uses three-way handshake to establish a connection. First handshake: when a connection is established, the client sends

We have explained some of the dhcp relay configurations. Here we will mainly introduce the dhcp relay handshake function and the security issue of disabling VLANs. How are these two configurations completed? ◆ Enable/disable dhcp security features on vlan interfaces When the client obtains an IP address from the dhcp server through dhcp relay, dhcp relay records the binding relationship between the IP address and the mac address. You can also manually

Three-time handshake for TCP connectionsFirst handshake: The client sends a SYN packet (SYN=J) to the server and enters the Syn_send state, waiting for the server to confirm;( The client asks the server: Do you love me? )Second handshake: The server receives the SYN packet, it must confirm the customer's SYN (ACK=J+1), and also send itself a SYN packet (syn=k),

TCP (transmission Control Protocol) transmission protocol. is a connection-oriented, reliable, byte-stream-based Transport layer communication protocol.TCP in the transmission before the three communication, generally known as the "three-time handshake" (Three-way handshake), the data is broken when the time to four communication, commonly known as "four Wave".Two serial numbers and three flag bits:(1) Seri

Background Due to the heart of openssl recently, I changed the ssl library 1.0.1g. I need to use this library to connect to the server. However, after I find that the Library is replaced, for some domain names, the ssl handshake will fail. In order to find out the cause of failure, we can find the handshaking status in the openssl tool.Tracking the ssl port of the Website 1. Tracking the handshake without a

in TCP/IP, TCP provides reliable connection services and uses three-way handshakes to establish a connection. first handshake: when a connection is established, the client sends the SYN Packet (SYN = J) to the server and enters the syn_send status, waiting for confirmation from the server. second handshake: when the server receives the SYN packet, it must confirm the customer's Syn (ACK = J + 1) and send

TCP connections: the three-way handshake The three-way handshake in Transmission Control Protocol (also called the three message handshake) is the method used to establish and tear down network connections. this handshaking technique is referred to as the 3-way handshake or as "SYN-SYN-ACK" (or more accurately SYN, SYN
