Discussion Prompt:

Asymmetric encryption (public-key cryptography) is a fundamental concept in modern cryptography, with algorithms like RSA and Diffie–Hellman playing pivotal roles. Answer all of the following prompts:

• Explain how asymmetric encryption differs from symmetric encryption in terms of key usage and security.
• Describe the basic principles of the RSA algorithm, focusing on key generation and encryption/decryption processes.
• How does the Diffie–Hellman key exchange protocol enable secure key sharing between two parties without a prior shared secret?
• Compare the advantages and disadvantages of asymmetric encryption with symmetric encryption, especially in terms of speed, security, and key management. In what situations would each type of encryption be preferred?
