To clarify the implementation principle of the HTTPS protocol, at least the following background knowledge is required.1. General understanding of the meaning of several basic terms (HTTPS, SSL, TLS)2. A general understanding of the relationship between HTTP and TCP (especially "short connections" VS "long Connections")3. A general understanding of the concept of cryptographic algorithms (especially the difference between symmetric and asymmetric encr

Use SSL to Build Secure Sockets Original bromon Copyright SSL (Secure Sockets Layer) was developed by Netscape in 1994 and was originally used in Web browsers to provide security for data transmission between browsers and servers, provides encryption, source authentication, and data integrity. SSL3.0 is now widely used, and its transport layer TLS (Transport Layer Security) has become the Internet standard

First, SSL1. About SSLThe SSL protocol is located between the TCP/IP protocol and various application layer protocols, providing security support for data communication. The SSL protocol can be divided into two tiers:SSL recording Protocol (SSL record Protocol): It is based on a reliable transport protocol (such as TCP) to provide high-level protocol data encapsu

In the past, I heard people say that an IP address can be used to generate a certificate. Today, the example shows that IP addresses cannot be used.Scenario 1: The name specified when the certificate is generated is IP Address The example is an example of single-point logon. The configuration in Web. XML is as follows: If the HTTPS protocol is specified in the above configuration and the name specified during certificate generation is 172.18.113.78, an error occurred while accessing the certi

In IIS7, HTTP. sys operates SSL encryption and decryption in kernel mode, which improves performance by nearly 20% compared with IIS6. When SSL runs in kernel mode, it stores the SSL binding information in two places. In the first place, the binding configuration is saved in % windir % \ System32 \ inetsrv \ config \ applicationHost. config. When the site is star

This article compares the IPSec VPN and ssl vpn technologies in detail, so that users from all walks of life can better understand the VPN technology and select the appropriate VPN product. Another VPN implementation technology different from the traditional VPN is the use of SSL-based VPN. This SSL-based VPN provides security similar to IPSec VPN. Because of

According to the document, if you want to implement the SSL socketchannel, a lot of code implementation will be involved, increasing the complexity of the API; the implementation of

Recent projects in the company involve a variety of encryption and security. I have always lacked experience in this area. It is a protocol that only knows what the concept is. Encrypted SSL for transport is also a painstaking. Very easy one thing, tossing for a long time. It's the line, really. The difficulty is not, the participants are difficult.About SSL-related concepts. The following website:Http://zh

SSL (secure Sockets layer), and its successor, TLS (Transport layer Security, Transport layer safety) is a security protocol that provides security and data integrity for network communications. TLS encrypts the network connection with SSL at the transport layer.Developed for Netscape to secure data transmission over the Internet, the use of encryption (encryption) technology ensures that data is not interc

1. HTTPS Concept 1) Introduction HTTPS (full name: Hypertext Transfer Protocol over Secure Socket Layer) is an HTTP channel targeted at security. It is simply a secure version of HTTP. That is, the SSL layer is added under HTTP. The Security Foundation of HTTPS is SSL, so the detailed content of encryption requires SSL. The system was initially developed by N

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
