Asymmetric Encryption

RSA Encryption and Decryption:

• Write a Python program that performs RSA encryption and decryption using your generated key pair.
• Encrypt the following message: "CRYPTOGRAPHY" (convert each character to its ASCII value).
• Decrypt the ciphertext back to the original message.

Diffie-Hellman Key Exchange:

• Write a Python program that performs the Diffie-Hellman key exchange using the provided values and private keys for Alice and Bob.
• The program should output both public keys and the shared secret key for both parties.
