OpenSSL provides a powerful feature in this area, and is open source, now widely used in the network communication mechanism;3. By deploying a CA (Certificate authority) server within a certain scope, the certificate authentication and authorization can be realized in the LAN, and the security of data transmission can be ensured, and the working principle of the international large CA institution may be un

the client and the server agree to use the TLS protocol, they negotiate a stateful connection to transfer the data by using a handshake process. By shaking hands, the client and server negotiate various parameters for creating a secure connection:When a client connects to a server that supports the TLS protocol, it requires the creation of a secure connection and lists the supported password combination handshake to start.The server determines the encryption and hashing functions from this list

Windows 2003 AD Upgrade to Windows-Ad CA Server MigrationIn the previous blog post we showed you how to upgrade Windows 2003 AD to Windows AD and the migration of the upgraded DHCP server, and today we will continue to introduce you to Windows 2003 AD upgrade to Windows 2012 After the ad, the CA server is migrated. Okay, nonsense, we're starting to experiment:The original

the busy channel. When the channel is busy, it indicates that the channel is busy either because the carrier listening on the physical layer detects that the channel is busy, or because the virtual carrier listening mechanism on the MAC layer indicates that the channel is busy. CSMA/CA working principle (1) first checks whether there is a STA in the channel. If the channel is detected to be idle, the data is sent only after the DIFS time. (

the security of network data transmission is an important subject in the field of computer communication, and data encryption is the main method to ensure data security. The so-called data encryption, that is, through a certain algorithm and key to the data plaintext processing, thus obtaining ciphertext process. The encryption forms in the process of computer network communication mainly include the following types: 1, symmetric encryption, The same key pair information encryption and decr

There are two kinds of data transmission on the Internet: plaintext transmission and encrypted transmission. PlainText transport protocols are: FTP, HTTP, SMTP, Telnet.

First, the Environment preparation:The 1.Weblogic comes with a JDK installation (one is JRO and the other is sun). If you generate a certificate request directly on the server, go to the bin directory of the path where the JDK is located under the WebLogic installation directory and run the Keytool command. (I am using this kind of)2. If you need to generate a certificate request file in a different environment, you can choose to install the JDK and l

First, generate certificate signing Request (CSR) in IIS Personal understanding: The generation of a CSR is the creation of a "private/public key pair" from which the public key is extracted. 1. Open IIS Manager, select Server certificates in the root node, click the Create certificate Request on the right ..., and then fill in the corresponding distinguished Name Properties (see figure below). Common name to fill in the domain name (if used for all level two domain name, fill *. domain nam
