Local thread storage TLS The local variables defined in the stack are safe for multithreading because different threads have their own stacks. Generally, the defined global variables can be read and written by all threads, so that they are not thread-safe. to ensure security, it is necessary to lock mutex access. What is Thread Local Storage (TLS), simply put, is a variable (usually a pointer pointing to a

With the development of the Internet, the demand for the network speed is more and more high, especially in the case of vigorously developing HTTPS, the TLS encryption protocol becomes very important. And Pat the cloud in the popularization of HTTPS and performance optimization, always do their own efforts and contributions. At the beginning of 2018, the cloud CDN network was deployed with TLS 1.3, which fu

A secure hash function (such as SHA and MD5) is used for Mac computing.The degree of acceptance of SSL is limited to HTTP only. It has been shown to be available in other protocols, but it has not been widely used.Second, TLS1.
