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
Before learning about the multi-domain wildcard SSL Certificate, we will first introduce the multi-domain certificate, also known as San certificate or UCC certificate, multi-domain certificates are described as follows:Multi-domain San/ucc
We need to submit an alias resolution based on the "detailed description" introduction. Or we can click "Confirm Request" first, then see the record that needs to add alias resolution.
Here we need to add the CNAME alias parsing record to the domain resolution panel.

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
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.

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. Considering the protection of customer privacy and security, according to relevant surveys, deploying SSL certificates of well-known brands on importan

The following uses the Win2000 Server version as an example to describe how to use SSL to encrypt the HTTP channel to enhance IIS security.
Procedure
The most recent project started with a self-built domain certificate, and the result is that the certificate cannot be added to a trusted certificate authority in IE outside of the domain (perhaps because of the inability to connect to the certification authority for the domains). Helpless, had to use MakeCert to create a self-signed

Ii. using OpenSSL to generate SSL Key and CSR
Because only the browser or the system trusted CA can let all visitors unobstructed access to your encrypted site, rather than a certificate error prompts. So we skip the steps from the visa book and start signing up for a third-party trusted SSL

About SSL Certificates I have written two articles, one is Nginx configuration, one is Tomcat configuration, HTTPS is very common.according to Let's Encrypt CA statistics, as of November 2017, Firefox-loaded web pages with HTTPS-enabled ratios accounted for 67%, a huge boost compared to 45% at the end of last year. Browser developers like Mozilla, Google is ready to take the next step: to mark all HTTP sites as unsafe.with The popularization of HTTPS,
Currently, many websites or services are implemented based on SSL and can be accessed only after certificates are downloaded and installed. If it can provide download, of course there are any problems.
However, if you do not have permission to download and it is not a CA certificate, it is only a self-Signed server certificate. Only know its port and address. If
