Details and differences between SSL and TLS security authentication protocols

SSL: (SecureSocketLayer, Secure Socket Layer) is a protocol layer between reliable connection-oriented network layer protocol and application layer protocol. SSL authenticates each other, uses digital signatures to ensure integrity, and uses encryption to ensure privacy, so as to achieve secure communication between the client and the server. The protocol consists of two layers: SSL record protocol and SSL Handshake Protocol. TLS :( TransportLay SSL:

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

WIN10 X64 with TLS for reverse debugging

1 Introduction to TLS technologyThread Local Storage (TLS) is a mechanism that Windows provides to address the simultaneous access of multiple threads in a process to global variables. TLS can simply be done by the operating system on its behalf to complete the mutex process, or the user can write their own function of controlling the semaphore. When a thread in

TLS for the network protocol

ObjectiveDue to the transmission of data in TCP, UDP, etc., it is possible for the packet to be intercepted by others and to parse out the information, which poses a great challenge to information security. The initial SSL protocol was proposed by Netscape, which does not affect upper-layer protocols (such as HTTP, e-mail, etc.), but can guarantee the communication security of the upper layer protocol. If SSL is used correctly, a third party can only infer the end addresses of the connection, th

Postfix Transport Layer Security Protocol (TLS)

The "Transport Layer Security Protocol" evolved from SSL can use encryption technology to protect the privacy of TCP communication (information leakage) and integrity (whether data is tampered with during transmission ). RFC 3207 specifies an extended mechanism called starttls for SMTP. Its main purpose is to ensure the privacy of point-to-point communication and ensure that your emails are not sent to the wrong place. For example, avoid shipping parcels to illegal systems disguised as recipient

"Deep Exchange 2013"15 TLS Transport Layer Security

By default, SMTP traffic is not encrypted, which leads to e-mail communication on the public network as if it were broadcast, and anyone who intercepts the message can easily read its contents. But there are many sensitive messages in the real world that are sent by mail, so one way to secure the message is to use the Transport Layer Security Protocol (Transport layer safety) to provide the encryption of the SMTP traffic in transit, TLS-protected SMTP

About the Linux thread stack and TLS

Note: A. this article describes the brief Implementation of the Linux nptl thread stack and the principle of local thread storage. In the experimental environment, the Linux kernel version is 2.6.32, the glibc version is 2.12.1, And the Linux release version is ubuntu, the hardware platform is a 32-bit x86 system.B. There are many topics about Linux nptl threads. This article selects the private address space of each thread for discussion, namely the thread stack and

Using go to implement TLS servers and clients

This is a creation in Article, where the information may have evolved or changed. The Transport Layer Security Protocol (TRANSPORT layer safety, abbreviation: TLS), and its predecessor, Secure Sockets Layer (secure Sockets layer, abbreviation: SSL) is a security protocol designed to provide security and data integrity assurance for Internet communications. SSL contains the record layer and the transport layer, and the recording layer protocol determin

HTTPS Transmission Optimization Detailed dynamic TLS Record Size

In the past, the author has analyzed many methods which can reduce the delay of HTTPS transmission, such as the reuse of distributed Session;With HSTS enabled, the client opens HTTPS jump by default, adopts HTTP/2 transport protocol, and uses chacha20-poly1305 algorithm to reduce the CPU time of the mobile terminal.These methods can greatly optimize the delay of HTTPS in transmission, and bring a better experience to the users of the website.Recently, I have also considered reducing the HTTPS tr

KTLS (Kernel SSL/TLS) principles and examples from Facebook

like AF_KTLS, but I've brushed it off again and again, until now, I've left the company, and I'm not even doing anything related to SSL/TLS or PKI, but suddenly let me know there's a ready-made solution from Facebook, It's been 2016 years! Facebook's program came from 2015, but we can actually do it earlier, but no, so I'm very sorry! The reason I'm saying this is because I almost don't need you to think about it. Step by step keep up with Dave Watso

HTTPS is not secure, the problem is on the low version of TLS

of measures to improve HTTPS performance: including HSTS (HTTP Strict Transport security,http Strict transport security), HTTP/2 (including Ser Ver Push), TLS 1.3 and other functions, in the domestic CDN market has been in a leading position. Recently, we have introduced the minimum TLS version management feature once again.Low version of TLSThe low version of TLS

TLS (Thread Local Storage) anti-debug principle

The special thing about TLS is that the program's entry point EP is not the first instruction to execute, so it is often used for anti-debug detection.Use an already open TLS program to do the instructions.DataTLS exists in the PE file format.

Install ProFTPd (TLS) on Ubuntu 16.04)

Install ProFTPd (TLS) on Ubuntu 16.04) This tutorial describes how to install and use ProFTPd securely. Without TLS, FTP is insecure because all passwords and data are transmitted in plaintext. By using TLS, the entire communication can be encrypted, so FTP makes it much safer. This article describes how to set up the use of ProFTPd

Securing Web Requests with TLS 1.2

In my development over the years, I can be sure that protecting network requests is a fundamental part of any mobile application. A few weeks ago one of my applications stopped working because I changed the Secure Sockets Layer (SSL) authentication on the mettup.com server, which made me realize that Transport Layer Security (TLS) plays an important role in ensuring application and server requests.I discussed TLS

HTTPS protocols: TLS, SSL, SNI, ALPN, PNP, snialpn

HTTPS protocols: TLS, SSL, SNI, ALPN, PNP, snialpn HTTPS is now widely used. It brings security while introducing more complicated concepts to the Web. This includes a series of network protocols that have never been seen before. Now, based on the principle of HTTPS, Harttle tries to interpret these protocols in the most popular way. HTTPS Overview HTTPS is an HTTP built on secure communication and uses transport layer encryption (

TLS learning Summary

We knowImmunity debugger, OD Debugger, Which is disconnected in OEP (modifying the first byte 0xcc) during program debugging ). I am wondering what programming technology is used and the code can be executed before OEP. I found some information on the Internet and saw many great bulls on the forum. I used static TLS to do a lot of interesting things. Now I am here to finish it myself.1. What is TLS?
