Cryptography is the study of protecting messages via codes and ciphers and the practice of creating algorithms for covert communication. Data is encrypted and decrypted using symmetric and asymmetric encryption in cryptography. As an IT Specialist, your role is to develop and evaluate mathematical models for data analysis and security issues, you want to design a plan for building training on the cryptographic systems, and your plan must include the main concepts and conducting the following:

1. Analyse the Diffie Hellman key exchange algorithm and its use in cryptography.

2.Specify the stream cipher and block cipher and show how they work using examples.

3.Contrast the key operational differences between stream cipher and block cipher in cryptography. Your comparison must include details about the Encryption Process, Decryption Process, Techniques Used, Speed, Implementation, and Example of the algorithm.

4.Explore the drawbacks of symmetric key distribution and investigate how message authentication codes and hash functions work to circumvent them.

5.Assess AES's improvements to the DES and 3DES encryption standards, as well as the public key and private key encryption.
