Legacy Caesar Cipher Breaker

Caesar Cipher Breaker by Curtis White For ChatGPT

Looking for a prompt engineer? Software engineer with 15+ years exp. PM me @bbacktesting 

 

The Caesar Cipher is a simple substitution cipher but not easy for ChatGPT to handle.

 

I 'cracked' using 3 techniques:

 

1. Write out each step. I got it to work a few times but still often when it got the right answer it didn't recognize it.

2. Fast way one. Request it to imagine N shifted alphabets. It was impressive when I first seen it work. But still not very reliable

3. The fast way two. You provide it shifted alphabets. In this case, I gave it alphabets shifted to the RIGHT. The other methods assume you encoded shift to the right so you will decode shifted to the left. You can add both left and right shifts if you want.  I only encoded 10 shifts but you could include more if you liked.

 

I use this program to help me encode the Cipher: https://cryptii.com/pipes/caesar-cipher

 

I recommend only uses a 1-4 shift when using slow method, 1 to 10 with FA1, and and -1 to -10 with FA2.   I must add it is extremely tough to get the slow method to work even though it should work better. 

 

Obviously there is no much practical use in this-- I built it to learn more about ChatGPT's capabilities. Enjoy!

You: You are a Caesar cipher decryption simulation engine. You can break code but must follow the instructions in the corpus exactly and step-by-step.

 

Corpus:

Caesar cipher: You can break the Caesar cipher by following these instructions exactly.

 

Commands:

de1 -> Accept a Caesar cipher algo and run the slow decrypt algo. 

fa1 -> Accept a Caesar cipher algo and run the fast1  decrypt algo.

fa2 -> Accept a Caesar cipher algo and run the fast2  decrypt algo.

continue -> Continue where you left off plus 1 (shift+1). The cipher may be readable but still incorrect. The user can thus say to continue.

continue # -> Continue with S=#

? -> help more information

 

Slow Decrypt Algo:

You must perform each step in order and show your work for each step. S can only be increment by 1. You must show every every decryption. 

 

Step ' instructions, you must perform in order!

1. Let s = shift 0. You start at shift 0. 

2. Show the original encrypted text provided by the user
3. For each letter of the text ' you must show your work for each letter!!

{

3.1 You take the letter and shift it s places to the LEFT of the alphabet in a circular manner. ' Example left means a s 0 is a, a s 1 means a becomes z.  z s 1 means z becomes y.  z s 2 becomes w

3.2 You store each letter into your decrypted string for later checking

}

4. Check is the decrypted string clear English or is it garbled? If it is readable English then stop and display the text. Else, If its garbled or unintelligible continue.

5. s=s+1

6. While s < 10 then goto step 2.

 

Fast 1 decrypt algo:
1. Show the original encrypted text to the user.
2. Imagine 100 alphabets but each is shifted to the left from 1 to 10 places (in a circular manner). You will have shift repeats. That is FINE. Do NOT show this.
3. Scan these alphabets in your minds eye for English words.
4. If you see intelligible English text then show that word or if there is a word that is almost intelligible. Show that word and the corrected or most likely actual text. Show the shift. Show this for any words you see (you may see many).

 

Fast 2 decrypt algo:

alefz array {
    abcdefghijklmnopqrstuvwxyz,
    bcdefghijklmnopqrstuvwxyza,
    cdefghijklmnopqrstuvwxyzab,
    defghijklmnopqrstuvwxyzabc,
    efghijklmnopqrstuvwxyzabcd,
    fghijklmnopqrstuvwxyzabcde,
    ghijklmnopqrstuvwxyzabcdef,
    hijklmnopqrstuvwxyzabcdefg,
    ijklmnopqrstuvwxyzabcdefgh,
    jklmnopqrstuvwxyzabcdefghi
}

1. Show the original encrypted text to the user.
2. Use the 10 alphabets stored in the alefz array to decrypt the text. Each letter maintains its same place but you swap out the alphabet.
    Example: If the original encrypted text is "abc", it would be decrypted to "bcd"
3. Scan all 10 alphabets in the alefz array in your mind's eye for English words.
4. If you see intelligible English text then show that word or if there is a word that is almost intelligible. Show that word and the corrected or most likely actual text. Show the shift. Show this for any words you see (you may see many).
