Encrypted SNI
Server Name Indication (SNI) is an extension to the Transport Layer Security (TLS) computer networking protocol by which a client indicates which hostname it is attempting to connect to at the start of the handshaking process. This allows a server to present one of multiple possible certificates on the same IP address and TCP port number and hence allows multiple secure ( HTTPS) websites (or any other service over TLS) to be served by the same IP address without requiring all those sites to use the same certificate. It is the conceptual equivalent to HTTP/1.1 name-based virtual hosting, but for HTTPS. This also allows a proxy to forward client traffic to the right server during TLS/SSL handshake. The desired hostname is not encrypted in the original SNI extension, so an eavesdropper can see which site is being requested. Background of the problem Prior to SNI, when making a TLS connection, the client had no way to specify which site it is trying to connect to. Hence, if one phy ...

Client (computing)
In computing, a client is a piece of computer hardware or software that accesses a service made available by a server as part of the client–server model of computer networks. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network. A client is a computer or a program that, as part of its operation, relies on sending a request to another program or a computer hardware or software that accesses a service made available by a server (which may or may not be located on another computer). For example, web browsers are clients that connect to web servers and retrieve web pages for display. Email clients retrieve email from mail servers. Online chat uses a variety of clients, which vary on the chat protocol being used. Multiplayer video games or online video games may run as a client on each computer. The term "client" may also be applied to computers or devices that run the client software or users that use th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Request For Comments
A Request for Comments (RFC) is a publication in a series from the principal technical development and standards-setting bodies for the Internet, most prominently the Internet Engineering Task Force (IETF). An RFC is authored by individuals or groups of engineers and computer scientists in the form of a memorandum describing methods, behaviors, research, or innovations applicable to the working of the Internet and Internet-connected systems. It is submitted either for peer review or to convey new concepts, information, or, occasionally, engineering humor. The IETF adopts some of the proposals published as RFCs as Internet Standards. However, many RFCs are informational or experimental in nature and are not standards. The RFC system was invented by Steve Crocker in 1969 to help record unofficial notes on the development of ARPANET. RFCs have since become official documents of Internet specifications, communications protocols, procedures, and events. According to Crocker, the doc ...

Microsoft Edge
Microsoft Edge is a proprietary, cross-platform web browser created by Microsoft. It was first released in 2015 as part of Windows 10 and Xbox One and later ported to other platforms as a fork of Google's Chromium open-source project: Android and iOS, macOS, older Windows versions (Windows 7 and later), and most recently Linux. It was created as the successor to Internet Explorer (IE). Edge was initially built with Microsoft's own proprietary browser engine, EdgeHTML, and their Chakra JavaScript engine. In late 2018, it was announced that Edge would be completely rebuilt as a Chromium-based browser with Blink and V8 engines. The new Edge was publicly released in January 2020, and on Xbox platforms in 2021. Microsoft has since terminated security support for the original browser (now referred to as Microsoft Edge Legacy), and in Windows 11 it is the default web browser (for compatibility with Google Chrome). In May 2022, according to StatCounter, Microsoft Edge became the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Explorer
Internet Explorer (formerly Microsoft Internet Explorer and Windows Internet Explorer, commonly abbreviated IE or MSIE) is a series of graphical user interface, graphical web browsers developed by Microsoft which was used in the Microsoft Windows, Windows line of operating systems (in Windows 11, Windows Server Insider Build 22463 and Windows Server Insider Build 25110, it is replaced by the Chromium (web browser), Chromium version of Microsoft Edge). Starting in 1995, It was first released as part of the add-on package Microsoft Plus!, Plus! for Windows 95 that year. Later versions were available as free downloads, or in-service packs, and included in the original equipment manufacturer (OEM) service releases of Windows 95 and later versions of Windows. Microsoft spent over per year on Internet Explorer in the late 1990s, with over 1,000 people involved in the project by 1999. New feature development for the browser was discontinued in 2016 in favor of new browser Microsoft Ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BSAFE
Dell BSAFE, formerly known as RSA BSAFE, is a FIPS 140-2 validated cryptography library, available in both C_(programming_language), C and Java_(programming_language), Java. BSAFE was initially created by RSA Security, which was purchased by Dell EMC, EMC and then, in turn, by Dell. When Dell sold the RSA business to Symphony Technology Group in 2020, Dell elected to retain the BSAFE product line. BSAFE was one of the most common encryption toolkits before the RSA_(cryptosystem)#Patent, RSA patent expired in September 2000. It also contained implementations of the RC''x'' ciphers, with the most common one being RC4. From 2004 to 2013 the default Random number generation, random number generator in the library was a National Institute of Standards and Technology, NIST-approved RNG standard, widely known to be insecure from at least 2006, containing a kleptographic backdoor (computing), backdoor from the American National Security Agency (NSA), as part of its secret Bullrun (decrypt ...

Email Client
An email client, email reader or, more formally, message user agent (MUA) or mail user agent is a computer program used to access and manage a user's email. A web application which provides message management, composition, and reception functions may act as a web email client, and a piece of computer hardware or software whose primary or most visible role is to work as an email client may also use the term. Retrieving messages from a mailbox Like most client programs, an email client is only active when a user runs it. The common arrangement is for an email user (the client) to make an arrangement with a remote Mail Transfer Agent (MTA) server for the receipt and storage of the client's emails. The MTA, using a suitable mail delivery agent (MDA), adds email messages to a client's storage as they arrive. The remote mail storage is referred to as the user's mailbox. The default setting on many Unix systems is for the mail server to store formatted messages in mbox, within the us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IMAP
In computing, the Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection. IMAP is defined by . IMAP was designed with the goal of permitting complete management of an email box by multiple email clients, therefore clients generally leave messages on the server until the user explicitly deletes them. An IMAP server typically listens on port number 143. IMAP over SSL/TLS (IMAPS) is assigned the port number 993. Virtually all modern e-mail clients and servers support IMAP, which along with the earlier POP3 (Post Office Protocol) are the two most prevalent standard protocols for email retrieval. Many webmail service providers such as Gmail and Outlook.com also provide support for both IMAP and POP3. Email protocols The Internet Message Access Protocol is an application layer Internet protocol that allows an e-mail client to access email on a remote mail server. The curr ...

Alpine (email Client)
Alpine is a free software email client developed at the University of Washington. Alpine is a rewrite of the Pine Message System that adds support for Unicode and other features. Alpine is meant to be suitable for both inexperienced email users and the most demanding of power users. Alpine can be learned by exploration and the use of context-sensitive help. The user interface can be customized. Features Alpine shares many common features of console applications, like a rich set of shortcut keys, using a keyboard instead of a mouse for all navigation and operations. In fact, all operations in Alpine have corresponding shortcut keys. Unlike other console applications targeting developers and experienced users, which often require users to edit a configuration file, Alpine lets users change most configuration options within the software. This makes alpine one of the most easy to learn console-based email clients. Alpine supports IMAP, POP, SMTP, NNTP and LDAP protocols natively. ...
