Handshake and communication over the SSL protocol To better understand and understand the SSL protocol, we will introduce the handshake protocol of the SSL protocol. SSL uses both public key encryption and symmetric encryption. Although symmetric encryption is faster than public key encryption, public key encryption pr

If our site projects are not important business sites, such as personal sites, blogs or simple projects need to use the SSL security certificate, in fact, the Internet currently provides a free SSL certificate enough for us to choose and use. In previous posts, Chiang has mentioned the perpetual free Let's Encrypt, Sta

At present, there are various types of websites. When we enter personal information on some websites, especially online banking transactions, how can we ensure that the websites you are facing are credible? By using the SSL Certificate of the website ID card, we can clearly understand whether the website is secure and trustworthy. Generally, the browser determines the security of these certificates. If we c

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.

Use SSL Certificate for connection in HAProxy I. Environment Introduction I was notified that the website should be changed from http to https. The current front-end architecture of my website is shown in: Suppose we have two physical machines with many tomcat containers on each physical machine. The front end uses the http layer Load Balancing conducted by haproxy, And then we use LVS load balancing on th

balancer to the Tomcat server, which means that the application server loses the ability to acquire the x-forwarded-* header, which contains the client IP address, port, and protocol used. There are two combinations of strategies, that is, the third, the SSL connection terminates at the load balancer, adjusts on demand, and then proxies to the backend server as a new SSL connection. This may provide ma

Using HTTPS does not make your site faster (it is actually possible, see below), but there are some tricks that can greatly reduce the extra overhead. First, as long as the text content is compressed, it reduces the CPU resources that are consumed by decoding. However, this overhead is trivial for modern CPUs. Second, an HTTPS connection is required, requiring additional TCP round trips, so that some bytes are sent and received. However, as you can see from the image below, the n

Gitlab Configure the mail delivery service will always not receive mail, check/var/log/mail.log, performance behavior for connection TLS and then disconnect, check Gitlab/log/sidekiq.log said Openssl::ssl::sslerror does Not match the server certificate The solution is: do not validate the An infinitely better solution (in terms of security, that's) than the accepted answer would be: ACTIONMAILER::BASE.S

: Digital Certificate: The name of a file, like the signature of an institution or person, that proves the authenticity of the institution or person. The information contained therein is used to implement the above functions. Encryption and authentication: encryption refers to the communication between the two parties in order to prevent most grateful information on the channel by the third party eavesdropping and leakage, will be p

Introduction (Creating a generated certificate can only be used for test use.) If you want to use a self-signed certificate, you can only issue certificates to the CA authority for two-way authentication to use. The use of HTTP (Hypertext Transfer) protocol to access data on the Internet is not encrypted. That is, anyone can intercept or listen to a stream of data that is transmitted over the network

When we do some exchange or Lync projects, we often use public network certificates, such as: We do exchange2013 and Office 365 hybrid deployment, or through the SEM staging migration or CEM direct conversion migration need to use the public network certificate, below for you to introduce 1 free SSL certificate and application method, I hope to help youIn order t

What is SSL?Originally developed by the Netscape Enterprise, the Secure Socket Layer (SSL) protocol is now a global standard for authenticating Web sites and web browser identities, and for encrypting communications between users of browsers and Web servers. Because SSL technology is built into all major browsers and Web server programs, you can only install digi

1. Will the SSL Certificate affect the speed and traffic? Encryption and decryption for each SSL connection will increase the processing workload of the server CPU.

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
