CrypTool is an open-source project [1] that is a free e-learning software for illustrating cryptographic and cryptanalytic concepts.
ISO 4217. An airline ticket showing the price with ISO 4217 code "EUR" (bottom left) and not with euro currency sign " € ". ISO 4217 is a standard published by the International Organization for Standardization (ISO) that defines alpha codes and numeric codes for the representation of currencies and provides information about the ...
Differential cryptanalysis is a general form of cryptanalysis applicable primarily to block ciphers, but also to stream ciphers and cryptographic hash functions. In the broadest sense, it is the study of how differences in information input can affect the resultant difference at the output. In the case of a block cipher, it refers to a set of ...
G2A.COM Limited (commonly referred to as G2A) is a digital marketplace headquartered in the Netherlands, [1][2] with offices in Poland and Hong Kong. [3][4] The site operates in the resale of gaming offers and others digital items by the use of redemption keys. G2A.COM’s main offerings are game key codes for platforms such as Steam, EA app, Uplay, PlayStation Network, Xbox, and Nintendo ...
A cryptocurrency, crypto-currency, or crypto[a] is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. [2]
Comparison of cryptography libraries. The tables below compare cryptography libraries that deal with cryptography algorithms and have application programming interface (API) function calls to each of the supported features.
In cryptography, an S-box (substitution-box) is a basic component of symmetric key algorithms which performs substitution. In block ciphers, they are typically used to obscure the relationship between the key and the ciphertext, thus ensuring Shannon's property of confusion. Mathematically, an S-box is a nonlinear [1] vectorial Boolean function.
Cryptanalysis (from the Greek kryptós, "hidden", and analýein, "to analyze") refers to the process of analyzing information systems in order to understand hidden aspects of the systems. [ 1 ] Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is ...
