The main functions of the HTTPS protocol are basically dependent on the TLS/SSL protocol, and this section analyzes how the TLS/SSL protocol works.The function implementation of TLS/SSL mainly relies on three kinds of basic algorithms: hash function hash, symmetric encryption and asymmetric encryption, which realizes identity authentication and key negotiation us

The SSL/TLS handshake process can be divided into two types: 1) SSL/TLS two-way authentication, that is, both sides will be mutual authentication, that is, the exchange of certificates between the two.2) SSL/TLS one-way authentication, the client authenticates the server side, and the server does not authenticate the client identity. We know that the handshake pr

Data communication and network note-SSL/TLS describes the two most important security protocols at the transport layer: Secure Sockets Layer (SSL) protocol and Transport Layer Security (TLS) protocol. TLS is actually the IETF version of SSL. 1. secure socket layer (SSL) is designed to provide secure compression services for data from the application layer. SSL ca

UseFileZilla ServerEstablish secureSSL/TLSFTP FileZilla is a free FTP solution, which can be divided into FileZilla Client and FileZilla Server. This article uses FileZilla Server to create an FTP Server and encrypted transmission. 1. Download and install Download the latest FileZilla Server FileZilla Server and FileZilla Client are different. FileZilla Server does not have a Chinese version, but they are both common English and not complex. Ii. Configure SSL/

For Python2.7, the built-in FTP_TLS class does not support FTP server operations that implicit FTP over TLS encryption, and in order to support implicit FTP over TLS encryption, the built-in FTP_TLS class must be overloaded, The specific code is as follows:ImportFtplibclassFtp_tls (ftplib. FTP_TLS):def __init__(Self, host="', user="', passwd="', acct="', Keyfile=none, Certfile=none, timeout=180): Ftplib. Ft

This week, cloudflare announced that it began to provide the keyless service, that is, you put the website on their CDN, without providing your own private key, you can also use SSL encrypted links. After reading cloudflare's instructions (here and here), I suddenly realized that this is an excellent example to illustrate the running mechanism of the SSL/TLS protocol. It is illustrated and easy to understand. Next, I will use these images as an examp

[Concurrent parallel] _ [C/C ++] _ [use a Thread to locally store Thread Local Storage (TLS) to call the copy file interface] Use Cases: 1. When copying a file, a thread generally calls an interface to copy the file. At this time, data needs to be cached. If each file needs to create an independent cache, the memory fragmentation is very large. If a static memory zone is created and multiple threads call the same interface using the same static cache

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
