Edouard Fleissner Von Wostrowitz
Edouard Fleissner von Wostrowitz (1825–1888), also spelt Fleißner, is remembered as the author of a short book on cryptography and as the proponent of a modified Cardan grille known as a '' turning grille''. He was born in Lemberg, the son of an Austrian cavalry officer, and was expected to follow a military career. After serving in the Chevaux-légeres Regiment Number 6, he was appointed Commandant of the Officer School at Ödenberg in 1871 and promoted to full colonel in 1872. Before retirement, at the end of 1874, he was ennobled and became ''Kommandant Oberst Edouard Freiherr von Fleißner von Wostrowitz''. His book ''Handbuch der Kryptographie'' was published in Vienna, in 1881. Jules Verne popularised the turning grille in his novel ''Mathias Sandorf'', published in 1885, by using it as a plot device. Later, the German Army adopted turning grilles of various sizes during the First World War for immediate cipher traffic. References to Fleißner are found in German, Fr ...

Cardan Grille
The Cardan grille is a method of writing secret messages using a grid. History This technique was used in ancient China. In 1550, Girolamo Cardano (1501–1576), known in French as , proposed a simple grid for writing hidden messages. He intended to cloak his messages inside an ordinary letter so that the whole would not appear to be a cipher at all. Such a disguised message is considered to be an example of steganography, which is a sub-branch of general cryptography. But the name Cardan was applied to grilles that may not have been Cardan's invention, and, so, ''Cardan'' is a generic name for cardboard grille ciphers. Cardinal Richelieu (1585–1642) was reputed to be fond of the Cardan grille and to have used it in both private and diplomatic correspondence. Educated men in 17th century Europe were familiar with word games in literature, including acrostics, anagrams, and ciphers. Although the original Cardan grilles were little used by the end of the 17th century, they st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grille (cryptography)
In the history of cryptography, a grille cipher was a technique for encrypting a plaintext by writing it onto a sheet of paper through a pierced sheet (of paper or cardboard or similar). The earliest known description is due to the polymath Girolamo Cardano in 1550. His proposal was for a rectangular stencil allowing single letters, syllables, or words to be written, then later read, through its various apertures. The written fragments of the plaintext could be further disguised by filling the gaps between the fragments with anodyne words or letters. This variant is also an example of steganography, as are many of the grille ciphers. Cardan grille and variations The Cardan grille was invented as a method of secret writing. The word ''cryptography'' became the more familiar term for secret communications from the middle of the 17th century. Earlier, the word ''steganography'' was common. The other general term for secret writing was ''cypher'' - also spelt ''cipher''. There is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mathias Sandorf
''Mathias Sandorf'' is an 1885 adventure book by French writer Jules Verne. It was first serialized in ''Le Temps'' in 1885, and it was Verne's epic Mediterranean adventure. It employs many of the devices that had served well in his earlier novels: islands, cryptograms, surprise revelations of identity, technically advanced hardware and a solitary figure bent on revenge. Verne dedicated the novel to the memory of Alexandre Dumas, ''père'', hoping to make ''Mathias Sandorf'' the ''Monte Cristo'' of ''Voyages Extraordinaires'' (''The Extraordinary Voyages'') series. Overview In Trieste, 1867, two petty criminals, Sarcany and Zirone, intercept a carrier pigeon. They find a ciphered message attached to its leg and uncover a plot to liberate Hungary from Habsburg-Austrian rule.

Military Personnel From Lviv
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From The Kingdom Of Galicia And Lodomeria
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

19th-century Austrian People
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
