The Importance of Cryptography in CTFs

Cryptography challenges are a staple in CTF competitions, testing participants' knowledge of encryption and decryption techniques. Whether it’s breaking classical ciphers like Caesar or Vigenère, or understanding modern encryption schemes like RSA or AES, these puzzles simulate real-world scenarios where secure communication or encrypted files need to be deciphered. Competitors must recognize different encryption patterns and apply appropriate tools and mathematical techniques to decrypt the message and reveal the hidden flag.
