tls heartbleed

BackgroundWhen we look at core issues, we sometimes need to look at the value of a certain TLS variable. But GDB doesn't provide direct commands, or I don't know. The purpose of this text. is to find out from the core file that a thread holds the contents of the TLS variable.BasisLinux glibc Library when creating threads. Use mmap to create a piece of memory space as the stack space for this thread. And str

ProblemHow to enable TLS 1.2 on Windows Server R2?ResolutionQuovadis recommends enabling and using the TLS 1.2 protocol on your server. TLS 1.2 have improvements over previous versions of the TLS and SSL protocol which would improve your level of security. By default, Windows Server R2 does not has this feature enabled

The default Fabric1.0.2 example is not based on TLS, but the Balance-transfer and e2e_cli examples are based on TLS, and in order to make the connection more secure and generic, the research supports the implementation of log monitoring based on TLS. The example/events/block-listener.go example in the Fabric1.0.2 source code produces the process of listening to t

The best way to learn the TLS protocol is to look at the RfC, but if there is no basic understanding of the secure transport protocol, it is difficult to read the details and design principles of the RFC, so here in order to be able to further understand the TLS protocol, put some basic knowledge here, is a sweep blind.1. The difference between TLS and SSL: SSL i

Some of the security techniques mentioned above, such as message digest, encryption and decryption algorithm, digital signature and data certificate, are not used directly by the developers, but have been encapsulated and even formed some security protocols, exposing certain interfaces for developers to use. Because of the direct use of these security tools, the cost of learning to developers is too high, need to understand the bottom line implementation, and directly use the interface exposed a

Openssl is an open-source implementation of SSL (applications can be downloaded for free). It is a secure and confidential program that is mainly used to improve the security of remote login access. It is also one of the tools currently used in encryption algorithms and has powerful functions.Openssl provides a security protocol for network communication security and data integrity, including key algorithms, common key and certificate encapsulation management functions (CA), and SSL protocols, i

What is the industrial Internet of things?In short, it is the specific application of the Internet of things in industrial control.What is SSL/TLS?SSL (secure Sockets layer Secure socket), and its successor Transport Layer Security (Transport layer Security,tls) is a security protocol that provides security and data integrity for network traffic. TLS encrypts the

SSL is the abbreviation for foreign language "secure Sockets layer", which is called "Secure Sockets Layer" in Chinese.It was designed by Netscape in the middle of the 90 century. (Incidentally, Netscape not only invented SSL, but also invented a lot of Web infrastructure-such as "CSS stylesheets" and "JS scripts").Why to invent SSL this protocol pinch? Because the HTTP protocol used on the internet is plaintext, there are a number of drawbacks-such as the fact that the transmitted content is pe
