- Boring Code. Boring code is when it makes perfect sense when you read it.
- Salt Mine Code. This is the type of code that’s bonkers and makes not a lick of sense.
- Radioactive Code. Radioactive code is the real problem at the heart of every engineering team.
What are common codes?
Common codes are values that enable a user to choose from a list of options rather than having to enter the data manually. Common codes can be made available to the user from drop-down lists in extended Sterling Order Management console screens.
How many codes are there?

Who invented secret codes?
One of the earliest use of ciphers was with the cipher disk, invented in Italy around 1470 by Leon Battista Alberti. The use of codes and ciphers in the military dates back to the beginning of the US Army Signal Corps which was formed in June of 1860.
How are codes cracked?
Most codes using a relatively simple substitution method are most easily cracked by doing a simple plug-and-chug, figuring out the letters one by one and patiently figuring out the code based on guesses.
How do I learn cipher codes?
Have your child follow these easy steps to use the Caesar Cipher.
- Write out the entire alphabet in a line.
- Choose a number to be your “rotation” amount.
- Under your first line, starting at the letter you “rotated” to, rewrite the alphabet.
- Decide what your message is going to say and write it on a piece of paper.
How do I create a code in Word?
Reflect the alphabet in half to encipher messages.
Write out the letters A through M in a single line on a piece of paper. Directly beneath this line, write out the letters N through Z also in a single line. Change each letter of messages to the opposite letter of the two lines of letters you have written out.
What is the Zodiac cipher?
The Zodiac sent four coded messages in total to the paper in 1969 and 1970. The first had 408 characters and was cracked in a week. The recently solved 340-character cipher was the second. After those, the killer sent two very short ciphers, one with 13 characters and the other with only 32.
