Sha (secure hash algorithm)
| Глоссарий по криптовалютам и блокчейну |
Is a family of cryptographic hash functions published by the national institute of standards and technology (nist) as a u.s. federal information processing standard (fips). sha256 is an algorithm used in bitcoin that takes an input of any size which can be any form of data(text, jpeg, pdf, etc.), mixes it up and creates a fixed size output(a hash) which is 256-bit (32-byte) long . you can think of the hash as the fingerprint of the data. hashes are one-way functions – they cannot be decrypted back. the only way to decrypt a hash is by brute forcing it. brute force means to systematically try all the combinations for an input. brute force attack will always find the input, no matter its complexity. the downside is whether or not you will still be alive when it finally guesses it

Cryptographic, английский
- Криптографический
- Криптографический; шифровальный
Technology, английский
- The use of tools and knowledge to meet human needs.
- Техника; технология
- Техника (означает все знания или неотъемлемую часть знаний о: научных принципах или открытиях; промышленных процессах; материальных и энергетических ресурсах; средствах транспорта и связи, постольку, поскольку эти знания непосредственно касаются развития производства товаров или сферы услуг; документы юнеско)
- N технология speech recognition ~ технология распознава- ния речи3
- Национальный институт стандартов и технологии
- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).
Information, английский
- Knowledge of a particular event or situation, or knowledge communicated or received concerning a particular fact.
- Информация
- Facts about something have you any information about the treatment of sunburn? the police won’t give us any information about how the accident happened. you haven’t given me enough information about when your symptoms started. that’s a very useful piece or bit of information. (note: no plural: some information; a piece of information.)
- N информация | attr. информационный flow, structure source of ~ источник информации 1 ранее использовался в более широком значении как ‘умозаключе- ние’. 2 получение выводных данных в процессе обработки информации и/или языка и само выводное знание, умозаключение; мыслительная операция, в ходе которой человек выходит за пределы данных в тек- сте сведений и получает новую информацию. 3 аффикс, вставляемый внутрь корня слова при словообразовании или словоизменении.
- In admiralty courts, implies a clause introduced into a citation, intimating that in the event of a party cited not appearing, the court will proceed in his absence.
- Информация; данные; сведения
- Координационный комитет ин4юрмации о проектируемых и возводимых объектах строительства
- Literally that which forms within, but more adequately
- Data that has been recorded, classified, organized, related or interpreted so that meaning is apparent.
- Contextualised data providing answer to a certain question decreasing uncertainty.
- Информация, сведения
Processing, английский
- Обработка (напр. данных); технология
- N обработка cognitive ~ когнитивная обработка language ~ когн.
- Обработка ~ of materials обработка [переработка] материалов
- A language originally designed for artists to allow them to do simple graphical design programs in a movie like paradigm.
- The preparation or packaging of fish to render it suitable for human consumption, retail sale, industrial use, or long-term storage, including but not limited to cooking, canning, smoking, salting, drying, filleting, freezing, or rendering into meal or oil, but not heading and gutting unless additional preparation is done.

- A mark left by a finger when something is touched. genetic
- Отпечаток; след; идентификационная метка; отличительная метка
- Any unique identifying characteristic on a diamond
Combinations, английский
The number of combinations of n things taken k at a time is the number of ways of picking a subset of k of the n things, without replacement, and without regard to the order in which the elements of the subset are picked. the number of such combinations is nck = n!/(k!(n−k)!), where k! (pronounced "k factorial") is k×(k−1)×(k−2)× … × 1. the numbers nck are also called the binomial coefficients. from a set that has n elements one can form a total of 2n subsets of all sizes. for example, from the set {a, b, c}, which has 3 elements, one can form the 23 = 8 subsets {}, {a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c}. because the number of subsets with k elements one can form from a set with n elements is nck, and the total number of subsets of a set is the sum of the numbers of possible subsets of each size, it follows that nc0+nc1+nc2+ … +ncn = 2n. the calculator has a button (ncm) that lets you compute the number of combinations of m things chosen from a set of n things. to use the button, first type the value of n, then push the ncm button, then type the value of m, then press the "=" button.
Complexity, английский
- Сложность
- Сложность; уровень сложности; комплексность
- Что-либо сложное
