Pidgin (software)
Pidgin (formerly named Gaim) is a free and open-source multi-platform instant messaging client, based on a library named libpurple that has support for many instant messaging protocols, allowing the user to simultaneously log in to various services from a single application, with a single interface for both popular and obsolete protocols (from AOL to Discord), thus avoiding the hassle of having to deal with a new software for each device and protocol. , the number of Pidgin users was estimated to be over three million. Pidgin is widely used for its Off-the-Record Messaging (OTR) plugin, which offers end-to-end encryption. For this reason it is included in the privacy- and anonymity-focused operating system Tails. History The program was originally written by Mark Spencer, an Auburn University sophomore, as an emulation of AOL's IM program AOL Instant Messenger on Linux using the GTK+ toolkit.Herper, Matthew (July 16, 2002)"Better Instant Messaging Through Linux"Forbes. ...

Free And Open-source Software
Free and open-source software (FOSS) is a term used to refer to groups of software consisting of both free software and open-source software where anyone is freely licensed to use, copy, study, and change the software in any way, and the source code is openly shared so that people are encouraged to voluntarily improve the design of the software. This is in contrast to proprietary software, where the software is under restrictive copyright licensing and the source code is usually hidden from the users. FOSS maintains the software user's civil liberty rights (see the Four Essential Freedoms, below). Other benefits of using FOSS can include decreased software costs, increased security and stability (especially in regard to malware), protecting privacy, education, and giving users more control over their own hardware. Free and open-source operating systems such as Linux and descendants of BSD are widely utilized today, powering millions of servers, desktops, smartphones (e.g ...

Tails (operating System)
Tails, or The Amnesic Incognito Live System, is a security-focused Debian-based Linux distribution aimed at preserving privacy and anonymity. It connects to the Internet exclusively through the anonymity network Tor. The system is designed to be booted as a live DVD or live USB, and leaves no digital footprint on the machine unless explicitly told to do so. It can also be run as a virtual machine, with some additional security risks. The Tor Project provided financial support for its development in the beginnings of the project, and continues to do so alongside numerous corporate and anonymous sponsors. History Tails was first released on June 23, 2009. It is the next iteration of development on Incognito, a discontinued Gentoo-based Linux distribution. The Tor Project provided financial support for its development in the beginnings of the project. Tails also received funding from the Open Technology Fund, Mozilla, and the Freedom of the Press Foundation. Laura Poi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
End-to-end Encryption
End-to-end encryption (E2EE) is a system of communication where only the communicating users can read the messages. In principle, it prevents potential eavesdroppers – including telecommunications service providers, telecom providers, Internet providers, malicious actors, and even the provider of the communication service – from being able to access the Key (cryptography), cryptographic keys needed to Encryption, decrypt the conversation. End-to-end encryption is intended to prevent data being read or secretly modified, other than by the true sender and recipient(s). The messages are encrypted by the sender but the third party does not have a means to decrypt them, and stores them encrypted. The recipients retrieve the encrypted data and decrypt it themselves. Because no third parties can decipher the data being communicated or stored, for example, companies that provide end-to-end encryption are unable to hand over texts of their customers' messages to the authorities.

Off-the-Record Messaging
Off-the-Record Messaging (OTR) is a cryptographic protocol that provides encryption for instant messaging conversations. OTR uses a combination of AES symmetric-key algorithm with 128 bits key length, the Diffie–Hellman key exchange with 1536 bits group size, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides forward secrecy and malleable encryption. The primary motivation behind the protocol was providing deniable authentication for the conversation participants while keeping conversations confidential, like a private conversation in real life, or off the record in journalism sourcing. This is in contrast with cryptography tools that produce output which can be later used as a verifiable record of the communication event and the identities of the participants. The initial introductory paper was named "Off-the-Record Communication, or, Why Not To Use PGP". The OTR protocol was designed by cryptographers Ian Goldberg and Nikita Borisov an ...

Discord (software)
Discord is a VoIP and instant messaging social platform. Users have the ability to communicate with voice calls, video calls, text messaging, media and files in private chats or as part of communities called "servers".The developer documentation refers to servers as "guilds". A server is a collection of persistent chat rooms and voice channels which can be accessed via invite links. Discord runs on Windows, macOS, Android, iOS, iPadOS, Linux, and in web browsers. , the service has over 350 million registered users and over 150 million monthly active users. History The concept of Discord came from Jason Citron, who had founded OpenFeint, a social gaming platform for mobile games, and Stanislav Vishnevskiy, who had founded Guildwork, another social gaming platform. Citron sold OpenFeint to GREE in 2011 for million, which he used to found Hammer & Chisel, a game development studio, in 2012. Their first product was '' Fates Forever'', released in 2014, which Citron antic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIM (software)
AIM (AOL Instant Messenger) was an instant messaging and presence computer program created by AOL, which used the proprietary OSCAR instant messaging protocol and the TOC protocol to allow registered users to communicate in real time. AIM was popular by the late 1990s, in United States and other countries, and was the leading instant messaging application in that region into the following decade. Teens and college students were known to use the messenger's away message feature to keep in touch with friends, often frequently changing their away message throughout a day or leaving a message up with one's computer left on to inform buddies of their ongoings, location, parties, thoughts, or jokes. AIM's popularity declined as AOL subscribers started decreasing and steeply towards the 2010s, as Gmail's Google Talk, SMS, and Internet social networks, like Facebook gained popularity. Its fall has often been compared with other once-popular Internet services, such as Myspace. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Login
In computer security, logging in (or logging on, signing in, or signing on) is the process by which an individual gains access to a computer system by identifying and authenticating themselves. The user credentials are typically some form of username and a matching password, and these credentials themselves are sometimes referred to as ''a'' login (or logon, sign-in, sign-on).Oxford Dictionaries definition of ''login''. detail and definition of ''login'' and ''logging in''. In practice, modern secure systems often require a second factor such as |
Protocol (computing)
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: ''protocols are t ...
