Cryptography challenges are all about puzzles wrapped in encryption. These tasks involve analyzing and breaking cryptographic schemes, understanding encoding formats, exploiting weak algorithms, or simply reversing engineered encryption logic.
Cryptography trains you to:
- Understand the basics of symmetric and asymmetric encryption
- Work with classical ciphers (Caesar, Vigenère) to modern ones (RSA, AES)
- Identify weak implementations of hashing, encoding, or key generation
- Use tools and scripting to automate cryptanalysis and decryption
