tls definition

To clarify the implementation principle of the HTTPS protocol, at least the following background knowledge is required.1. General understanding of the meaning of several basic terms (HTTPS, SSL, TLS)2. A general understanding of the relationship between HTTP and TCP (especially "short connections" VS "long Connections")3. A general understanding of the concept of cryptographic algorithms (especially the difference between symmetric and asymmetric encr

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

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

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

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

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

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
