The development of CrypTool started in 1998. Originally developed by German companies and universities, it is an open-source project since 2001. [2]Currently 4 versions of CrypTool are maintained and developed: The CrypTool 1 (CT1) software is available in 6 languages (English, German, Polish, Spanish, Serbian, and French).
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.
Reconstruction of the appearance of cyclometer, a device used to break the encryption of the Enigma machine.Based on sketches in Marian Rejewski's memoirs.. 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]

This table denotes, if a cryptography library provides the technical requisites for FIPS 140, and the status of their FIPS 140 certification (according to NIST's CMVP search, [27] modules in process list [28] and implementation under test list). [29]
The procedure for constructing approximations is different for each cipher. In the most basic type of block cipher, a substitution–permutation network, analysis is concentrated primarily on the S-boxes, the only nonlinear part of the cipher (i.e. the operation of an S-box cannot be encoded in a linear equation). For small enough S-boxes, it ...
is a book about cryptography written by Steven Levy, published in 2001. Levy details the emergence of public key cryptography, digital signatures and the struggle between the National Security Agency and the "cypherpunks". The book details the creation of Data Encryption Standard (DES), RSA and the Clipper chip. [1]
Blockchain analysis is the process of inspecting, identifying, clustering, modeling and visually representing data on a cryptographic distributed-ledger known as a blockchain. [ 1 ] [ 2 ] The goal of blockchain analysis is to discover useful information about different actors transacting in cryptocurrency.
