Analysis

1. We are given encrypted messagemessage.txt

2. Using dcode cipher identifier we find that cipher is either ROT13 or Caesar Cipher

   • Note: Ciphers are technically the same since they both use rotation as encryption.

Solution

I used Caesar Cipher from dcode to solve the challenge

Output gives proper readable text. Reading the text we find the flag hint.You can use REDACTED as flag but dont forget to format.

Final flag would be: SecVal{REDACTED}
