This paper introduces some basic problems of SSL bidirectional authentication, and uses nginx+php to build HTTPS webservice based on it.The previous approach was just to implement the 1:1 pattern, and yesterday colleagues continued to implement the N:1 model, and here I'm going to sort it out.Since Nginx's ssl_client_certificate parameter can only specify a client public key, it is necessary to re-match a server if a client is added to communicate.The N:1 pattern is implemented through the CA's
The previous article introduced some basic questions about SSL two-way authentication and used nginx + PHP to build https-based WebService.
The previous method only implemented the mode. Yesterday, my colleagues continued to implement the N: 1 mode. Here I will record it again.
Because the ssl_client_certificate parameter of nginx can only specify one client public key, if a client is added for communication, a server is required.
The N: 1 mode is implemented through the CA cascade certificate m
the previous approach was just to implement the 1:1 pattern, and yesterday colleagues continued to implement the N:1 model, and here I'm going to sort it out. Since Nginx's ssl_client_certificate parameter can only specify a client public key, it is necessary to re-match a server if a client is added to communicate. The N:1 pattern is implemented through the CA's cascading certificate pattern, first generating a set of CA root-level certificates and then generating level two certificates as cl

What is HTTPS? HTTP is called Hypertext Transfer Protocol, using TCP port 80, by default the data is transmitted in clear text, the data can be captured through the capture tool, so on Interner, some of the more important sites of the HTTP server need to use PKI (Public Key Infrastructure) technology to encrypt data! This is also the HTTPS;HTTPS is called a secure Hypertext Transfer protocol, using TCP port 443, his data will be encrypted with the pub

◆ Anti-virus software: today, there is no anti-virus software in one day, and it will not be steadfast in one day. We strongly recommend that you use anti-virus software on the broadband access network, such as Norton, McAfee, TrendMicro, CA, rising, Kingsoft drug overlord, and beixin source VRV.
◆ Encryption: for particularly sensitive communication, you must consider encrypting the communication on the PC. A firew
IP address has been 61.52.80. *, but recently it has become 221.15.145 .*. In this case, only a fixed IP address can be managed.
Since Version 11.0 of PcAnyWhere, it supports SecurID dual authentication. Using SecurID authentication, you do not need to restrict the IP address at all. The other party cannot connect even if they know the user name and password of PcAnyWhere.
TIPS: This article describes the PcAnyWhere SecurID dual authentication mechanism. If you are not familiar with PcAnyWhere,
