I. The Bedrock of Cryptography Cryptography is built on two main pillars: symmetric-key cryptography and public-key cryptography.Symmetric-Key Cryptography: This involves the use of a single key that is shared between the sender and receiver. It is fast and efficient but poses challenges in key distribution and management. AES (Advanced Encryption Standard) is a widely used symmetric algorithm.Public-Key Cryptography: This system uses a pair of keys, one public and one private. It solves the ...
