You may write in any language, use a code or cipher, no matter, a fac-simile is produced here.

Most attempts have tried other historical texts as keys ( e. g., the Magna Carta, various books of the Bible, the U. S. Constitution, and the Virginia Royal Charter ), assuming the ciphertexts were produced with some book cipher, but none have been recognized as successful to date.

A good tutorial on reconstructing the key for a four-square cipher can be found in chapter 7, " Solution to Polygraphic Substitution Systems ," of Field Manual 34-40-2, produced by the United States Army.

A good tutorial on reconstructing the key for a two-square cipher can be found in chapter 7, " Solution to Polygraphic Substitution Systems ," of Field Manual 34-40-2, produced by the United States Army.

The ( Hagelin ) CD-57 was a portable, mechanical cipher machine manufactured by Crypto AG, first produced in 1957.

On its own, this would produce statistically identifiable deviations from randomness ; for instance, generating 2 < sup > 65 </ sup > genuinely random 128-bit blocks would produce on average about one pair of identical blocks, but there are no repeated blocks at all among the first 2 < sup > 128 </ sup > produced by a 128-bit cipher in counter mode.

During the 1980s, mandated regulations not unlike Public, educational, and government access ( PEG ) channels created the beginning of the Cable-originated live television program that evolved into what we know today in 2012 where many cable networks provide live cable-only broadcasts of many varieties, cable-only produced television movies, and miniseries.

Significantly unlike Abrams, the cases of Schenck, Frohwerk, and Debs had all produced unanimous decisions.

Bibles were the major item of trade in China, unlike India where educational books topped the lists, even if Oxford's lavishly produced and expensive Bible editions were not very competitive beside cheap American ones.

However, unlike a typewriter or daisy wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced.

However, unlike a typewriter or daisy wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced.

France also produced large numbers of similar tiny vehicles called voiturettes, but unlike the German makes, these were rarely sold abroad.

It might have been due to ancient assumptions that Sparta was too " spartan " ever to have produced a talented poet of its own, or because Tyrtaeus didn't compose in the Doric dialect or vernacular of Sparta ( unlike his near contemporary, Alcman ) but imitated the conventional literary dialect of Homer, which was Ionian.
