1. Reasons for using thread-local storageWhen we want the global variables of this process to become thread-private, instead of shared by all threads, that is, when each thread has a copy, the thread-local storage (tls,thread local Storage) mechanism can be used.2. Dynamic TLS(1) Call the TlsAlloc functionTwo different ways:1> Global Call once : Global_dwtlsindex=tlsalloc ();If the program calls only once t
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
Firefox 52: supports TLS 1.3GuideMozilla announced that it plans to support TLS 1.3 in Firefox 52, which will be released next year. TLS 1.3 is the latest version of the TLS security protocol currently under development. Earlier, Mozilla added support for TLS June in the dev
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.

I. The handshake process of SSL/TLS
In the SSL/TLS handshake process, the client and the server need to exchange parameters, the specific process is as follows: The client provides the various cipher suites that it supports (including cryptographic algorithms and hash functions) from which the server chooses itself and supports cipher Suiteand notifies the client that both will be used for this data transfe

1st log is a plain text file that the system uses to record some relevant information about the system at run time
The purpose of the 2nd log is to save the running status, error messages, etc. of the related programs. In order to analyze the system, save the history and find the parse error using when the error occurs
