WebNov 16, 2010 · Rainbow tables are constructed of "chains" of a certain length: 100,000 for example. To construct the chain, pick a random seed value. Then apply the hashing and reduction functions to this seed, and its output, and continue iterating 100,000 times. Only the seed and final value are stored.

It has the alphabet written out 26 times in different rows, each alphabet shifted cyclically to the left compared to the previous alphabet, corresponding to the 26 possible Caesar ciphers. See more The Vigenère cipher is a method of encrypting alphabetic text by using a series of interwoven Caesar ciphers, based on the letters of a keyword. It employs a form of polyalphabetic substitution. First described by See more In a Caesar cipher, each letter of the alphabet is shifted along some number of places. For example, in a Caesar cipher of shift 3, a would … See more The idea behind the Vigenère cipher, like all other polyalphabetic ciphers, is to disguise the plaintext letter frequency to interfere with a straightforward application of frequency analysis. For instance, if P is the most frequent letter in a ciphertext whose plaintext is in See more • Roger Frontenac (Nostradamus quatrain decryptor, 1950) See more The very first well-documented description of a polyalphabetic cipher was by Leon Battista Alberti around 1467 and used a metal cipher disk to switch between cipher alphabets.
