A prefaceThe first thing to clarify is the confusion of names:1 SSL (Secure Socket Layer) is a secure transport protocol designed primarily for the web by Netscape Corporation. This kind of protocol has been widely used on the web.The 2 IETF (www.ietf.org) standardizes SSL, RFC2246, which is called TLS (Transport Layer Security), and technically, the difference between TLS1.0 and SSL3.0 is very small. Since this article does not deal with the small di

TlsFirst say TLS (Thread Local Storage), which is explained on the wiki:thread-local Storage (TLS) is a computer programming method, uses static or global memory local to a thread.Thread Local Storage (TLS) is a computer programming technique that uses static or global memory to store thread-local variables (transliteration).The goal is to implement variable isol

Https SSL/TLS PreMaster/Master Secret (Key) computing Many people are confused about how the PreMaster/Master Secret (Key) is calculated when studying Https SSL/TLS. Recently, by looking at other materials and openssl source code, summarize the computing process of the PreMaster/Master Secret (Key: Both Client Random and Server Random are explained in the previous "Https (SSL/

The project involves invoking the webservice of the third-party HTTPS, and I am using the original HttpWebRequest.The code has taken into account the HTTPS, plus the SSL3 protocol, plus the delegate invocation. But occasionally, I still come acrossThe request was aborted:could not create the SSL/TLS secure channel.Such a mistake.So according to this blog, change it to use the TLS protocol to see if there is

SuperSocket supports transport layer encryption (TLS/SSL) In Sync Mode ). First, you need to prepare the Certificate file (with a private key) for encryption ). Certificates used for testing can be generated (http://supersocket.codeplex.com/releases/view/59311) by the CertificateCreator of the SuperSocket, and then (*. pfx) is imported into the trusted Certificate directory of the test server. The certificate in the production environment must submit

Note:Through the author's blog "working principle of the FTP server and how to log on to a virtual user through PAM Authentication", we learned that FTP is a file sharing protocol and uses a plaintext transmission mechanism, therefore, users and passwords transmitted over the Internet are insecure. Therefore, the SSL/TLS encryption algorithm must be used to provide the ciphertext transmission mechanism to ensure the security of users and passwords dur

Because of the requirements of Apple ATS, Tomcat server requirements on the https+tls1.2, the front of the HTTPS, but TLS has been 1.0, even a year of running the server restarted, does not solve the problem.Ideas are as follows:1. Upgrade the OPENJDK to 1.8, since 1.8 Java will support TLS 1.2 by default, or 1.02. Tomcat Server.xml Modified:Restart TomcatFinally supported the tls1.2.Attached:1. The Symante

SSL (secure Sockets layer), and its successor, TLS (Transport layer Security, Transport layer safety) is a security protocol that provides security and data integrity for network communications. TLS encrypts the network connection with SSL at the transport layer. Developed for Netscape to secure data transmission over the Internet, the use of encryption (encryption) technology ensures that data is not inter

Thread Local variable introduction can solve the problem of non-synchronization of static or global variables modified by multiple threads. For a simple example, a function FN may need to modify a static variable. The intention of writing this function is to call the function in its own thread, but if other threads may call this function, the value of this static variable may be damaged. Use local variables of the thread to ensure that each thread uses its own copy and does not interfere with ea

Thread Local Storage (TLS) enables multiple threads of the same process to use an index allocated byTlsallocFunction to store and retrieve a value that is local to the thread. in this example, an index is allocated when the process starts. when each thread starts, it allocates a block of dynamic memory and stores a pointer to this memory in the TLS slot usingTlssetvalueFunction.
