In my development over the years, I can be sure that protecting network requests is a fundamental part of any mobile application. A few weeks ago one of my applications stopped working because I changed the Secure Sockets Layer (SSL) authentication on the mettup.com server, which made me realize that Transport Layer Security (TLS) plays an important role in ensuring application and server requests.I discussed TLS
(SHA series)HTTPS uses all of the above three encryption algorithms .2. the role of HTTPSHTTP communications that do not use SSL/TLS are non-encrypted traffic. All information is transmitted in plaintext, bringing three major risks.
(1) eavesdropping risk (eavesdropping): Third parties can learn the content of the communication.
(2) tamper risk (tampering): Third parties may modify the content of the communication.
(3) impersonation
SSL/TLS is no longer a strange word, but its principles and rules are not too easy to remember. This article will try to show the principle of the process through some simple illustrations, hoping that the reader has something to gain.first, the relevant version

HTTPS is now widely used. It brings security while introducing more complicated concepts to the Web. This includes a series of network protocols that have never been seen before. Now, based on the principle of HTTPS, Harttle tries to interpret these protocols in the most popular way.
HTTPS Overview
HTTPS is an HTTP built on secure communication and uses transport layer encryption (
After human established the communication system, how to ensure the security of communication is always an important problem. With the establishment of modern communication system, people use mathematical theory to find some effective methods to ensure the security of digital communication. In simple terms, the process of the two-party communication is treated confidentially, such as the content of the communication between the parties to encrypt, so that can effectively prevent the listener eas
PostfixForTlsYes. It is provided by a set of patch files written by lutz janicke. This set of patch files can be obtained from the add-on software link on the postfix homepage. If you use the pre-compiled postfix package that is included with the platform, make sure that this version does contain the tls patch.
In addition to the tls support for postfix, you must create and set the
The communication security of the Internet is built on the SSL/TLS protocol.
This article briefly introduces the operation mechanism of the SSL/TLS protocol. The focus of this article is on the design idea and operation process, with no specific implementation details involved. For more information, see the RFC documentation.
