When MySQL is replicating across the internet, others can steal information about MySQL's replication, which is plaintext, so there is no security, where the replicated information is encrypted via SSL. When the client does not have a fixed IP to access the server, MySQL to allow access to arbitrary addresses, server and client through certificate validation can prevent violent cracking. Before we begin, let's review the installation process for

The general FTP server is in plaintext transmission of data, security is very poor, information is easily stolen, even if it provides SSL encryption, by default may not be enabled, such as the Common Serv-u FTP server (hereinafter referred to as Serv-u). In order to ensure data security in a particular environment, it is sometimes necessary to enable SSL functionality. The following is an example of a serv-

was established by Alice in the message.A digital signature is established with an encrypted message digest and other information (such as a serial number) and the sender's private key. Although it is possible for anyone to decrypt a signature with a public key, only the issuer knows its private key, that is, only the holder of the key can issue it. The digest contained in the signature is valid only for that message, to ensure that no one can change

In order to ensure data security in a particular environment, it is sometimes necessary to enable SSL functionality. The following is an example of a serv-u server that describes how to enable SSL encryption. Creating an SSL Certificate To use the Serv-u SSL feature, you will of course need the

SSL BasicsWhen most of the current remote access solutions use a VPN Network Based on the IPSec security protocol, A new study shows that almost 90% of enterprises use VPN for Intranet and external network connections only for Internet access and email communication, in addition, 10% of users use non-Internet applications such as X11, chat protocols, and other private client applications. These 90% applications can use a simpler VPN technology-

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, Startssl, Wosign SSL, in fact, free

This article describes how to configure SSL support in Tomcat. 1. It is easier to configure SSL support in Tomcat. There are several steps: (1) If the JVM version is earlier than 1.3, You need to download JSSE, which is a Java SSL support library. Since JDK 1.4, JSSE has been built into JDK. Therefore, this step can be omitted. (2) execute the command (in Linu

2.1VPN Introduction VPN (VirtualPrivateNetwork) refers to the technology for establishing a private network on a public network. The connection between any two nodes of the VPN network is not a point-to-point physical link required by the traditional private network, but a logical network built on the network platform provided by the public network service provider ISP. User data is transmitted through a logical tunnel (point-to-point virtual line) established by the ISP in the public network,

SSL: (SecureSocketLayer, Secure Socket Layer) is a protocol layer between reliable connection-oriented network layer protocol and application layer protocol. SSL authenticates each other, uses digital signatures to ensure integrity, and uses encryption to ensure privacy, so as to achieve secure communication between the client and the server. The protocol consists of two layers:

There are many scenarios for using SSL on Python, and my main concern is to use Python to access HTTPS resources and to use Python to provide HTTPS services. (HTTPS is one of the SSL applications on the Web)I. Using python to access HTTPS websitesThis should be the simplest and most common scenario. We use Python as a client to access the public Web site, and this site for the transmission of security (to a

In the previous blog, the first step in speaking of SSL was to create a certificate. (or buy from a third party) PS: The final on-line product, the certificate will be to the Third-party certification body to buy, but in the development process, is created by themselves. The common tool for creating certificates is Keytool, a JDK-only tool that can be used if the computer is installed with JDK (and the environment variables are configured). Linux syst

First, what is HTTPS? According to Wikipedia's explanation: Hypertext Transfer Security Protocol (abbreviated: HTTPS, English: Hypertext Transfer Protocol Secure) is a combination of Hypertext Transfer Protocol and SSL/TLS to provide encrypted communication and authentication of network server identities. HTTPS connections are often used for transactional payments on the World Wide Web and for the transmission of sensitive information in enterpr
