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.). Also include what the difference is between a hashing algorithm and an encryption.
