There are many ways to write a ticket in code. Based on the secrecy of what you have to say, these methods can change dramatically. Here are a few to write a ticket in code that is easily and indecipherable. The only problem is that the recipient must also know the code!
Steps
Method 1 of 4: New Language
Step 1. Create a new language
If the encrypted ticket is for one person (or a small group), you can create a language in which each letter is replaced by a symbol. Make sure the other person knows the code, or include a list where each letter has a match in a symbol. It should be simple enough to remember, but also mysterious enough so that it isn't too easy to translate. (For example, A = 1, B = 2, C = 3 is too simple a code. A better one might be a spiral for A, a triangle for B, a star for C, and so on).
Method 2 of 4: Hide the message
Step 1. Write a hidden message
Dip a brush in milk or lemon and write your message on a white sheet of paper. Let it dry. To decode it, heat the sheet with a hair dryer.
Step 2. Use scotch tape
Cover a sheet of paper with tape. Write the message with a marker. If your teacher catches your friend reading the message, he can delete it before he gets to the desk.
Method 3 of 4: Codes
Step 1. Replace one letter with another
A replacement code consists of replacing one letter with another. A = Z is too easy. Try random combinations like M = B. It is even more difficult to decipher if the words are in a single line of letters.
Step 2. Use transposition
Write the original sentence in a 6x6 table and then write the letters column by column. For example, a sentence like: There really is a lot of flour, Jhon, will become: cvnio 'etnn èraa dof, ataj varh..
Step 3. Follow the snake method
Similar to transposition, the snake method consists of rearranging the letters up and down, like a snake. Again using the same table or a larger one based on the length of the message, transcribe the sentence vertically and then copy the letters following the order of the lines, this time. After you are done, draw a small snake to indicate that you have used the snake method.
Step 4. Use an undecipherable method
- Choose a text of a few hundred words.
- Assign a numerical value to each letter. Most of the letters should have enough numbers to replace them with. As long as the coded message does not contain the same number repeated over and over it is impossible to decipher without knowing the base code. For example, You cannot read it becomes 66 45 78 9 76 5 43 21 34 98 7 1 23 U 34 32 90 when encoded using the text in this passage as a basis. However, if the text doesn't have a word starting with a certain letter you could use the letter itself, like the U in the example. t
Method 4 of 4: Bilingual
Step 1. Swap the letters of your alphabet with those of another
For example, swap A with (α) Alpha, B with (β) Beta, C with (Χ) Chi (but not gamma, do you understand how this works? Use similar sounding letters) and so on.
Step 2. Include a hint at the beginning (optional) to tell your friend what language you are using
The recipient needs to know the language you are using so you can make suggestions at the beginning.
For example, you can start the letter like this: Hey, today's Greek lesson was great, right?. This will tell the recipient that you will replace the Italian letters with the Greek ones
Step 3. To avoid confusion, the letter should be short
Don't use the same letter of your chosen language multiple times in the same word. The foreign alphabet may not contain all the letters of yours, so choose your words carefully.
Step 4. Never, under any circumstances, mention the date or time
Use a code that hides the numbers. If you write "8% ^! 00 @ 22", this will make every inspector understand that it is a code and not random scribbles, and that something will happen at 10pm.
Step 5. Here are some examples:
- "Tonight, at 8, it becomes Today's Greek lesson was great, wasn't it? Στασερα √ (128/2). The 8 has been replaced by a mathematical formula, the square root of (128/2 = 64) = 8 and tonight written in Greek script.
- Another example. You want to write A tonight. To code it with the Greek alphabet, you can do this: Today's Greek lesson was great, right? Α ΣΤΑΣΕΡΑ.
Advice
- Try to come up with a secret code that is difficult for strangers to crack, but simple for you and the recipient to understand.
- Also, avoid contact with people who don't have to read the contents of your messages.
- Don't do this too often or your teacher will get suspicious.
- You can always write the message in another language.
-
Try not to use spaces in your codes.
- The spaces tell the intruder that the word contains a certain number of letters.
- Try using symbols instead of spaces to make the message more difficult to decipher. Hyphens and underscores are too easy to find, so try to use actual symbols that represent letters. Only the group that knows how to decipher the code will be able to determine whether the symbol is a letter or a space.
- If you write a message, never write something inappropriate. You could end up in serious trouble.
Warnings
- Have you ever read The Da Vinci Code or Digital Fortress? There are people who by profession decipher codes for various governments and private organizations. If you think you are writing something that could make even a vague reference to an illegal activity, it won't be long before someone finds out what you wrote.
- Remember that wetting the paper for step 2 can make it very brittle.
- While most codes (using these basic concepts) are virtually undecipherable, they can be decoded by trial and error, but it would take a long time.
- Keep in mind that any code you use can be cracked with a computer and the right determination. There is a reason behind 128-bit encription keys (which are no longer considered secure).
