The previous article describes a code instance of SSL/TLS bidirectional authentication.You can also choose to use one-way authentication, in which case the client side does not need to provide a certificate. SoServer side only need to own the KeyStore file, do not need Truststore fileThe client side does not need its own KeyStore file, only the Truststore file (which contains the server's public key).Additionally, the server side needs to set the clie

It uses APIs, X.509, PKCS #12, OpenPGP, and other security data types for network communication encryption. The group password decryption logi

What is Timelog?When we analyze the performance of the program, we add some logging information to record the time information of each part.The function of the Timelog module is to provide a unified interface to allow adding and saving loggingThe timelog we're using has several drawbacks.1. Fixed size, once full, can not join the new logging2. Each entry will have a global lock lock, which greatly affects the performanceThis two-day boost-based thread_specific_ptr and circular_buffer achieve an

These copies are actually allocated to the heap, And the allocation process occurs when each thread is accessed for the first time. CThreadLocal reloads operator->. When each thread accesses its members for the first time, it will create a new CMyThreadData and place it on the stack.What does CThreadLocal rely on? Remember which CMyThreadData on the stack belongs to which thread? The an

Some highly secure web pages, such as online payment or user login pages, may use HTTPS (SSL/TLS) to improve security. This article describes how to force an action to Use https in ASP. net mvc and how to redirect to an HTTPS page. First, we need to force an action to Use https. Here, a requirehttpsattribute is written, which is used to convert non-HTTPS connections to HTTPS connections, so that all controllers using the filter requirehttps will force

OpenVPN Optimization-Establishment of TLS handshake Control CHannelAn optimization of the OpenVPN data tunnel is in progress. After referring to the concept and idea of the "giant frame", I carefully considered the design and implementation of the TCP/IP protocol stack, so I come up with a possible error, but at least it is very practical in my scenario: although the upper-layer protocol sends data, it doesn't matter the data size. If it really needs

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. Th

Usage scenarios:1. When copying files, it is common for a thread to call an interface to copy files, which requires caching the data, and if each file needs to create a separate cache, the memory fragmentation is large.If you create a static memory area, when multithreading calls the same interface, multiple threads using the same static cache can cause data pollution. The best way is that the cache is visible only to this thread,Creates a buffer when the thread is created and destroys the buffe
