The Cipher Conspiracy
The Cipher Conspiracy refers to a covert operation involving encrypted messages, secret codes, and hidden agendas used to manipulate or control information. It often involves intelligence agencies, hackers, or secret societies using cryptographic techniques to conceal their activities. This concept is popular in espionage, cyber warfare, and historical mysteries, where decoding hidden messages can unveil shocking truths.
A rogue group known as "The Silent Hand" has been using highly advanced encryption techniques to communicate their plans for a series of covert operations. Your mission is to intercept and decrypt their messages before it’s too late. Each message is encoded using different encryption techniques, some of which are vulnerable to attacks. Can you crack them in time?

This CTF challenge takes participants through a series of progressively difficult cryptography challenges, from classic encryption methods like Caesar and Vigenère ciphers to modern encryption algorithms like RSA, AES, and ECC. The final flag is formed by solving each of these challenges, testing both theoretical cryptographic knowledge and practical skills in attacking encryption schemes
