The Rossignols, a family of French cryptographers and cryptanalysts, included Antoine Rossignol (1600–1682), Bonaventure Rossignol and Antoine-Bonaventure Rossignol. The family name means "nightingale" in French. As early as 1406, the word rossignol has served as the French term for "skeleton key" or for any tool which opens that which is ...
Hashing is a common technique used in cryptography to encode information quickly using typical algorithms. Generally, an algorithm is applied to a string of text, and the resulting string becomes the "hash value". This creates a "digital fingerprint" of the message, as the specific hash value is used to identify a specific message.
English version cover page, 1797 French version cover page, 1797. Syllabical and Steganographical Table (French: Tableau syllabique et stéganographique) is an eighteenth-century cryptographical work by P. R. Wouves. Published by Benjamin Franklin Bache in 1797, it provided a method for representing pairs of letters by numbers. It may have been ...
Augustus the Younger, Duke of Brunswick-Lüneburg, wrote a standard book on cryptography; Ibn Wahshiyya: published several cipher alphabets that were used to encrypt magic formulas. [1] John Dee, wrote an occult book, which in fact was a cover for crypted text
The Vigenère cipher (French pronunciation: [viʒnɛːʁ]) is a method of encrypting alphabetic text where each letter of the plaintext is encoded with a different Caesar cipher, whose increment is determined by the corresponding letter of another text, the key. For example, if the plaintext is attacking tonight and the key is ...
The Great Cipher (French: Grand chiffre) was a nomenclator cipher developed by the Rossignols, several generations of whom served the French monarchs as cryptographers. The Great Cipher was so named because of its excellence and because it was reputed to be unbreakable. Modified forms were in use by the French Peninsular army until the summer ...
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία-logia, "study", respectively [1]), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
1989 – Quantum cryptography experimentally demonstrated in a proof-of-the-principle experiment by Charles Bennett et al. 1991 – Phil Zimmermann releases the public key encryption program PGP along with its source code, which quickly appears on the Internet. 1994 – Bruce Schneier's Applied Cryptography is published.
