tls definition

SSL: Specifies a Data Security score between the Application Protocol (HTTP, telnet, nntp, FTP) and TCP/IP. Layer mechanism. Provides data encryption, server authentication, message integrity, and optional client authentication for TCP/IP connections. .Difference between SSL and TLS: TLS can be seen as an upgraded version of SSL. The main difference is that the supported encryption algorithms are different.

Recently engaged in an Android version of the Spice protocol. After the Andorid-spice official GitHub code is downloaded, the compilation succeeds and runs smoothly on the Android system to link to the cloud desktop, in the case of non-secure ports can be successfully linked to the virtual cloud desktop, But it's very, very annoying, when you link to a TLS port, you always link to a cloud desktop, and the backend reports a bunch of SSL bugs. After rep

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

Resolution of the latest SSL/TLS Vulnerabilities In March 2015, about 30% of network communication was protected by RC4. Through the attack, attackers can only use sniffing listening in a specific environment to restore plain text in encrypted information protected by RC4, this results in exposure of important sensitive information such as accounts, passwords, and credit card information, and session hijacking can be performed through Man-in-the-middl
