Cryptosystems and protocols: Cryptosystem is a method used to hide data from the unauthorized access and the protocols are used to ensure the security of the system at the time of transaction and sharing details. Most popular cryptosystem and protocols are TLS/SSL (Transport Layer Security / Secure Sockets Layer) and HTTPS (Hypertext Transfer Protocol Secure).

Question

Please respond to the following question in a few sentences. In comparison to RSA, what potential benefits does elliptic curve cryptography (ECC) have? Do digital signatures offer confidentiality? Give a quick explanation. What exactly is meant by the term "public-key certificate"?

Cryptography involves five important concepts, integrity, confidentiality, authentication, non-repudiation, and digital signatures. Please describe the technical process, in detail, that involves sending an encrypted email from a sender to a receiver. Be sure to include and describe the technical details for each of the five concepts and the cryptography that takes place. (i.e SHA, AES, RSA, etc.). Please include in our discussion what the difference between a hashing algorithm and an encryption.
