It contains different codes where very applicable to all of you who loves mysteries. I also includes all of my learnings and studies that talks about unfamiliar ideas or codes stuffs. I make it for my own book and I want to share it to all of my co...
These top 10 codes, keys and ciphers are from Kevin Sands.
Kevin Sands, author of The Blackthorn Key, picks his favourite keys, codes and ciphers throughout history, from the Caesar shift to the Enigma machine.
1. The Caesar shift
Named after Julius Caesar, who used it to encode his military messages, the Caesar shift is as simple as a cipher gets. All you have to do is substitute each letter in the alphabet by shifting it right or left by a specific number of letters. Today, we can break this code in our sleep, but it took ancient codebreakers 800 years to learn how to crack it - and nearly another 800 years to come up with anything better.

2. Alberti’s disk
In 1467, architect Leon Battista Alberti described a curious device. It was a disk made up of two concentric rings: the outer ring engraved with a standard alphabet, and the inner ring, engraved with the same alphabet but written out of order. By rotating the inner ring and matching letters across the disk, a message could be enciphered, one letter at a time, in a fiendishly complex way.
