Tags: vsftpd + SSL Vsftpd + SSL/TLS for secure communication As mentioned in previous articles, FTP is transmitted in plain text, so it is easy for people to get their accounts and passwords. To implement secure FTP transmission, we need to use SSL/TLS to implement secure communication. Of course, there are two secure FTP communication methods: One is implemented using SSL/TLS. The other is implemented through SSH + FTP. Here we will only introduce how to implement secure FTP communication throu

consider security issues, from the most basic LAN to the Web server how to allow external users to access Web pages via SSL (secure Sockets Layer, Secure Sockets Layer). Also, all aspects of security need to be taken into consideration, especially when deploying a CA or PKI (public key Infrastructure). Of course, the benefits of security are self-evident, and improving the security of the enterprise network and system protects the enterprise from var

1 CA Introduction Ca is the certificate issuing authority and is the core of PKI. Ca is the authority responsible for issuing certificates, certification certificates, and managing issued certificates. It requires policies and specific steps to verify and identify user identities, and sign user certificates to ensure the identity andPublic Key. For example, Alice communicates with Bob. In the event of intercommunication being monitored by hacker C, im

From the Keystone configuration file, we can see that the token provider currently supports four kinds of them. Token Provider:uuid, PKI, Pkiz, or Fernet Combining source and official documentation, we use a table to illustrate the differences between them.

Deploy and build an https (SSL/TLS) Local test environment under IIS In Win10 System Sometimes we want to deploy some XX projects in the company as https sites to Encrypt transmission at the transmission layer to prevent others from sniffing important site data, the http method we use is usually plain text transmission, which is very insecure and easy to be stolen by others. In some cases, you need to build an https environment locally for testing. The following describes how to build an https t
