This section explores in detail Asymmetric Cryptography and what happens at each stage of encryption/decryption and why a hash is neither symmetric nor asymmetric. We explain how Asymmetric Cryptography actually delivers all 4 encryption services: privacy, authenticity, integrity, non-repudiation (PAIN). Then we explain what happens at each state of asymmetric cryptography, what info is required I the exchanged between public and private key, how packet verification occurs, and how a hash is created and hashing algorithms used, and what comprises a digital signature.
