Global trusted SSL Digital certificate request: http://www.shuzizhengshu.comIn the Internet Secure Communication mode, the most used is HTTPS with SSL and digital certificates to ensure the security of transmission and authentication. This article has been traced around this model for a brief discussion.noun explanationFirst explain some of the above nouns:

I have prepared it. Well, the following is my note. For details, enter the author name: wingger.In this article, we will test the certificate on Linux9 + apache2.0.52, tomcat5.5.6, j2se1.5, and openssl0.97.The purpose of this article is to communicate. If any errors occur, please advise.Reprinted, please indica
After you enable Apache Mod_ssl, you need a certificate to function properly. Wrote a script to manipulate it. The first thing to make sure is that there are OpenSSL on the machine.
Copy Code code as follows:

First, you need to understand some basic concepts before installing
1. Certificates used by SSL can be self-generated or signed by a commercial ca such as Verisign or thawte.
2. Certificate concept: First, you must have a root certificate, and then use the root certificate to issue the server
SSL is a commonly used WEB Service encryption channel. Its full name is Secure Socket Layer, which is also known as the Secure sockets interface. It uses digital certificates to ensure its security mechanism. The main function is encryption and authentication to protect the security of network transmission. It is in the middle of the HTTP and TCP layers.
SSL encryption and authentication use public keys and
The following is a Java certificate: HTTPS and SSL application notes test. I hope this article will help you.
When a connection is obtained, like a normal browser, the server certificate is still verified to be trusted (issued by an authority or signed by an authority). If the server certificate is untrusted, the defau

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
HTTPS access to a Web site, server-side and client data transmission is encrypted, will not be intercepted, than the normal HTTP protocol more secure. Let me introduce the configuration of SSL under IIS6.0 to achieve HTTPS access. Detailed process screenshots are described.
1, enter the site properties, select Directory Security, and then click on the server certificate to configure the
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
lower than that of symmetric encryption and decryption algorithms. Therefore, SSL uses asymmetric cryptographic algorithms to negotiate keys during the handshake process, and uses symmetric encryption and decryption methods to Encrypt transmission of HTTP content. The following is a metaphor for the image of this process (from http://blog.chinaunix.net/u2/82806/showart_1341720.html ):
Assume that a communicates with B, A is an
The SSL certificate for the server recently expired and needs to be replaced.
Then after the replacement, request the other interface, there is an error.

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
(also the TCP client) sends a Clienth*llo after the TCP link is established, which contains the list of algorithms that it can implement and some other required messages.2. The server side of SSL responds to a Serverh*llo, which determines the algorithm required for this communication, and then sends its own certificate (which contains the identity and its own public key).3. When the client receives this m
