In understanding Grotjan's skills, the author's discussion of code-breaking revealed that coded messages are made up of numbers and letters in a pattern. Each of the symbol in the pattern usually represent a letter. Whenever the machine moves, a letter tends to move and a symbol stands out for something different. This makes such code difficult to solve, decipher and decode.

In order to break the codes, cryptanalysts use guess work. They try out a combination of letters.

For example, in cracking Japan's diplomatic coded messages, cryptanalysts used a combination of letters from this Japanese popular saying: "I have the honour to inform Your Excellency".

They tried out a combination of letters through guessing.

Explanation:

Grotjan's discovery in World War II led to the development of a Purple Cipher machine which was built by SIS and the U. S Navy. It was used to read and decode Japan's most diplomatic messages. People saw the breaking of Japan's diplomatic coded messages as a "magic".

"Cracking Code Purple" is an informational text written by Ann Ouchychy. It reveals the impact of Genevieve Grotjan, a female code breaker during World War II.
