1 SSL (Secure Socket lclientyer) is a secure transport protocol designed primarily for Weserver by NETSCCLIENTPE Corporation. This kind of protocol has been widely used in weserver.SSL establishes an encrypted channel on top of TCP, and the data through this layer is encrypted, thus achieving a confidential effect.The SSL protocol is divided into two parts: Hclientndshclientke Protocol and record Protocol.W

We all know that MySQL master-slave replication is transmitted in plain text, which is not allowed for some special businesses. Next we will try to build an SSL-based master-slave replication environment: RHEL5.8SELinux disabled, iptables disabled, and MySQL5.5. We all know that MySQL master-slave replication is transmitted in plain text, which is not allowed for some special businesses. Next we will try to build an

. Obtain the fingerprint of the certificate (the fingerprint of the certificate is required in the following two processes ). Bind the SSL Certificate to the port configuration. Bind the SSL Certificate to the port configuration and support the client certificate. Deletes an SSL certificate from a port number. Note that privilege management is required to mo

Wootong is the only ca in China that owns the 1999 old root certificate; Sandvine, a network service provider, recently released a report that mentions a very interesting phenomenon: compared with last year's data, encrypted network traffic (SSL) is experiencing explosive growth this year. This change is evident in Europe: the share of SSL traffic throughout Europe this year has quadrupled to 1.47% during

1. After OpenSSL is installed, find OpenSSL. CnF in the/usr/lib/SSL directory (for Ubuntu system, use whereis to check the SSL directory) and copy it to the working directory. 2. Create a New democafolder under the Work directory, create the new files index.txt and serial in the folder, and then create a newcerts folder. Add the character 01 to serial. Mkdir democa CD democa Touch./{serial, index.txt} Add 0

Today more and more of our web sites start using SSL certificates, not only limited in the electric business site, portal, and even many personal websites, blogs have to open SSL security in the certificate, and the old left is also considering whether to install the blog SSL certificate, has been prepared to add, because this theme used a lot of old directory ,

In short, the so-called mitm attack intercepts normal network communication data and conducts data tampering and sniffing, while the communication parties have no idea.With the continuou

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 t

(The server I/O thread is responsible for reading the master binary log, then writing itself to the relay log and then reading the relay log with its own SQL thread and executing it on its own server.) ）The changes on the master server are synch

interested in the market of remote control software. To improve the security level of Remote Desktop and ensure that data is not stolen by hackers, a Secure Authentication Remote Desktop function is added to the latest patch package SP1 in Windows2003. With this function, we can use SSL encrypted information to transmit and control the data of remote servers, thus making up for the original security defects of the Remote Desktop function. Tip: if you

SSL (secure Sockets layer), and its successor, TLS (Transport layer Security, Transport layer safety) is a security protocol that provides security and data integrity for network communications. TLS encrypts the network connection with SSL at the transport layer.Developed for Netscape to secure data transmission over the Internet, the use of encryption (encryption) technology ensures that data is not interc

Recently with the Green League scanning system for the entire network system scanning, several devices were swept out of the SSL-related vulnerabilities, here to make a short note.This involves a vulnerability1.

This article chooses Nginx and MySQL to cooperate with Gitlab to realize the function of Web management, data storage and so on, the difficulty of configuration is basically in Gitlab script modification, SSH secret key connection, Nginx SSL certificate and so on, the author also consumes very big strength, Combined with a lot of documents clue and many foreigners debug comment, finally finally completed, I hope to give you a chance to explore the SCM

Based on the previous security protocol analysis of the SSL protocol, first review the content of the SSL protocol and then use Wireshark to grasp the contents of the specific flow of packets. The SSL protocol stack is located between the TCP and the application layer, and is divided into the SSL record protocol layer

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,
