Cipher
Devices are designed to make codes unreadable to anyone but the
person meant to receive it. This is usually done by switching letters
and numbers with other letters to making it look like a jumbled up
mess of letters and numbers to anyone who reads it.
In
1934, a man named Boris Hegelian invented a cipher machine for the
french secret service. During World War II, over 14,000 of the
machines were made for the U.S.
Today,
cipher devices are still being used. The most simple one used is made
of two wheels, one inside another.
Others
are more complicated, using 25 or more whhiles to make a cipher.
Hey, Nightfury! I know Morse Code and I have a spot on my blog, Tale Wag, dedicated to it! It's called Morse Almighty and it's a collecting of posts in Morse Code. Just like the blog itself, its works in posts, but they are separated by big letters. Oops, I mean dots and dashes! Go to www.talewag.blogspot.com and have fun deciphering it!
