The obese stripfiguur cryptogram is a cipher that uses a combination of letters and numbers to encrypt messages. The cipher is based on the following rules:
- Each letter is assigned a number, with A=1, B=2, and so on.
- Numbers are grouped together in pairs.
- The first number in each pair represents the row of the letter in a 10×10 grid.
- The second number in each pair represents the column of the letter in the grid.
- To encrypt a message, simply convert each letter to its corresponding number and then group the numbers together in pairs.
- To decrypt a message, simply reverse the process, converting each pair of numbers to its corresponding letter.
For example, to encrypt the message “HELLO WORLD”, we would first convert each letter to its corresponding number:
H = 8 E = 5 L = 12 O = 15 W = 23 R = 18 L = 12 D = 4
We would then group the numbers together in pairs:
85 1215 2318 124
This is the encrypted message.
To decrypt the message, we would simply reverse the process, converting each pair of numbers to its corresponding letter:
85 = H 1215 = E 2318 = L 124 = L O = 15 W = 23 R = 18 D = 4
The decrypted message is “HELLO WORLD”.
The obese stripfiguur cryptogram is a relatively simple cipher, but it can be made more difficult by using a larger grid or by adding additional rules, such as requiring that certain letters or pairs of letters never appear together.
