Facebook Onion Address
The Facebook onion address located at facebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd.onionhttps://www.facebook.com/onion-service (formerly facebookcorewwwi.onion) is a site that allows access to Facebook through the Tor protocol, using its .onion top-level domain. Purported benefits Prior to the release of an official .onion domain, accessing Facebook through Tor would sometimes lead to error messages and inability to access the website. ProPublica explicitly referenced the existence of Facebook's .onion site when they started their own onion service. The site also makes it easier for Facebook to differentiate between accounts that have been caught up in a botnet and those that legitimately access Facebook through Tor. As of its 2014 release, the site was still in early stages, with much work remaining to polish the code for Tor access. It has been speculated that other companies will follow suit and release their own Tor-accessible sites. History In October 201 ...

ZDNet
ZDNET is a business technology news website owned and operated by Red Ventures. The brand was founded on April 1, 1991, as a general interest technology portal from Ziff Davis and evolved into an enterprise IT-focused online publication. History Beginnings: 1991 to 1995 ZDNET began as a subscription-based digital service called "ZiffNet" that offered computing information to users of CompuServe. It featured computer industry forums, events, features and searchable archives. Initially, ZiffNet was intended to serve as a common place to find content from all Ziff-Davis print publications. As such, ZiffNet was an expansion on an earlier online service called PCMagNet for readers of PC Magazine. Launched in 1988, PCMagNet in turn was the evolution of Ziff Davis' first electronic publishing venture, a bulletin board, which launched in 1985. On June 20, 1995, Ziff-Davis announced the consolidation of its online information services under a single name, ''ZD Net''. The servi ...

Hash Collision
In computer science, a hash collision or hash clash is when two pieces of data in a hash table share the same hash value. The hash value in this case is derived from a hash function which takes a data input and returns a fixed length of bits. Although hash algorithms have been created with the intent of being collision resistant, they can still sometimes map different data to the same hash (by virtue of the pigeonhole principle). Malicious users can take advantage of this to mimic, access, or alter data. Due to the possible negative applications of hash collisions in data management and computer security (in particular, cryptographic hash functions), collision avoidance has become an important topic in computer security. Background Hash collisions can be unavoidable depending on the number of objects in a set and whether or not the bit string they are mapped to is long enough in length. When there is a set of ''n'' objects, if ''n'' is greater than , ''R'', , which in this c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brute-force Attack
In cryptography, a brute-force attack consists of an attacker submitting many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found. Alternatively, the attacker can attempt to guess the key which is typically created from the password using a key derivation function. This is known as an exhaustive key search. A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the task easier. When password-guessing, this method is very fast when used to check all short passwords, but for longer passwords other methods such as the dictionary attack are used because a brute-force search ...

Censorship Of Facebook
Facebook is a social networking service that has been gradually replacing traditional media channels since 2010. Facebook has limited moderation of the content posted to its site. Because the site indiscriminately displays material publicly posted by users, Facebook can, in effect, threaten oppressive governments. Facebook can simultaneously propagate fake news, hate speech, and misinformation, thereby undermining the credibility of online platforms and social media. Many countries have banned or temporarily limited access to Facebook. Use of the website has also been restricted in various ways in other countries. As of July 2022, the only countries to continually ban access to the social networking site are China, Iran, North Korea, and Russia. However, since most North Korean residents have no access to the Internet, China, Russia, and Iran are the only countries where access to Facebook is actively restricted in a wholesale manner, although it is possible to access the site ...

Backronym
A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The word is a portmanteau of ''back'' and ''acronym''. An acronym is a word derived from the initial letters of the words of a phrase, such as ''radar'' from "''ra''dio ''d''etection ''a''nd ''r''anging". By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin." Many fictional espionage organizations are backronyms, such as SPECTRE (''sp''ecial ''e''xecutive for ''c''ounterintelligence, ''t''errorism, ''r''evenge and ''e''xtortion) from the James Bond franchise. For example, the Amber Alert missing-child program was named after Amber Hagerman, a nine-year-old girl who was abduct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tor Project
Tor, short for The Onion Router, is free and open-source software for enabling Anonymity, anonymous communication. It directs Internet traffic through a free, worldwide, volunteer overlay network, consisting of more than seven thousand relays, to conceal a user's location and usage from anyone performing Computer and network surveillance#Network surveillance, network surveillance or Traffic analysis#In computer security, traffic analysis. Using Tor makes it more difficult to trace a user's Internet activity. Tor's intended use is to protect the personal privacy of its users, as well as their freedom and ability to communicate confidentially through IP address anonymity using Tor exit nodes. History The core principle of Tor, onion routing, was developed in the mid-1990s by United States Naval Research Laboratory employees, mathematician Paul Syverson, and computer scientists Michael G.

HTTPS
Hypertext Transfer Protocol Secure (HTTPS) is an extension of the Hypertext Transfer Protocol (HTTP). It is used for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security (TLS) or, formerly, Secure Sockets Layer (SSL). The protocol is therefore also referred to as HTTP over TLS, or HTTP over SSL. The principal motivations for HTTPS are authentication of the accessed website, and protection of the privacy and integrity of the exchanged data while in transit. It protects against man-in-the-middle attacks, and the bidirectional encryption of communications between a client and server protects the communications against eavesdropping and tampering. The authentication aspect of HTTPS requires a trusted third party to sign server-side digital certificates. This was historically an expensive operation, which meant fully authenticated HTTPS connections were usually found o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
