change of application software sales model, software users may not need to buy software to install and run on local computers in the future, instead, the data to be processed is uploaded to the application server that runs the software service over the network for processing, and the data processing result is obtained through the network. The software developer charges the software fee by providing the application service. At this time, software vendors are no longer faced with how to prevent l

Therefore, this article will discuss how to use smart trust and authorization technology based on PKI/PMI to establish a trusted environment for IP Broadband man, how to Apply digital certificate authentication,

Implement simple RSA key generation and encryption/decryption (Java), rsajava Recently I have been studying PKI and have come into contact with some encryption algorithms. I focused on RSA and wrote a simple Demo to implement the RSA algorithm, including public and private key generation and encryption and decryption. Although relatively simple, it also covers the core ideas and processes of RSA encryption and decryption. Here we will share it with yo

certification authority. These certificates cost money, but they add to the reputation of the network service provider. Get readyIn this document, we will use a self-signed certificate. Assume that CentOS has an Apache Web server installed. We need to generate a self-signed certificate using OpenSSL. If OpenSSL is not already installed, it can be installed using Yum.# yum Install mod_ssl OpenSSLGenerate a self-signed certificateThe following command can be used to generate a self-signed ce
