I. The Essence of Cryptography Cryptography is the practice and study of techniques for secure communication in the presence of adversaries. It encompasses a variety of methods that allow parties to keep their information secure and private:Symmetric Cryptography: This method uses the same key for both encryption and decryption. It is fast and efficient but requires secure key exchange between parties. AES (Advanced Encryption Standard) is a widely adopted symmetric algorithm.Asymmetric Crypt...
