SSL/TLS Security Series: SSL/TLS Overview

TLS: Local TLS storage for threads

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

security is the same.3) Pseudo-random function: TLS is a more secure way to use pseudo-random functions called PRF to extend a key into a block of data.4) Alarm code: TLS supports almost all SSLv3.0 alarm codes, and TLS also complements the definition of many alarm codes, such as decryption failure (decryption_failed)

The principle of SSL/TLS and how the Internet Works (3)-TLS's special session

Me: hi,tls! This is your special session! Tls:ok, then I'll start! First of all, my name is called Transport Layer Security Protocol (Transport Layer Secure Protocol), which is an upgraded version of SSL. In fact, my left and right hand are able to use the left hand is called record layer (record), the right hand is called handshake layer (handshake layer) ...Me: Hey, wait a minute, record layer? The handshake layer? What the hell is all this?

Details and differences between SSL and TLS security authentication protocols

secret.8) fill: The number of bytes to be added before data encryption. In SSL, the data length after filling must be a minimum integer multiple of the length of the ciphertext block. In TLS, the data length after filling can be any integer multiple of the length of the ciphertext block (but the maximum length of filling is 255 bytes ), this method can prevent attacks based on the analysis of the packet length.2. main

Resolution of request suspension: unable to establish SSL/TLS Security channel (the request was aborted: cocould not create SSL/TLS Secure Channel)

When I used httpwebrequest to access other websites, the error "the request was aborted: unable to establish SSL/TLS Secure Channel" appeared. So goog and Baidu compared the problem. The answer is servicepointmanager. servercertificatevalidationcallback write delegate Public responsemodel gethtml (string URL) {servicepointmanager. servercertificatevalidationcallback = validateservercertificate; httpwebrequest request = (httpwebrequest) webrequest. cr

About the Linux thread stack and TLS

to the private space of the current thread. If the main thread or other threads are willing, you can also access this space by other means. After understanding the general principles, let's take a look at how everything is associated. First, let's take a look at the definition of gdt segments in the Linux kernel, as shown in: We found that the sixth segment was used to record TLS data. I confirmed that I

Enable TLS 1.3 Encryption protocol, ultra-fast HTTPS experience

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

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

Windows TLS (thread local storage)

Windows TLS (thread local storage)I. TLS description and classificationWe know that in a process, all threads are sharing the same address space. So, if a variable is global or static, then all threads are accessing the same part, and if one thread modifies it, it affects all other threads. However, we may not want this, so it is more recommended to use a stack-based automatic variable or function parameter
