Man In The Middle Attack
A man in the middle attack is a type of software attack where an attacker inserts himself between two hosts to gain access to their data transmissions. The attacker captures and reads each packet, responds to it, and forwards it to the intended host, so that both the sender and receiver believe that they are communicating directly with each other. This deception allows attackers to manipulate the communication rather than just observe it passively.

CPKI is a two-key system. Messages are encrypted with a public key. Messages are decrypted with a private key. If you want to send an encrypted message to someone, you would request their public key. You would encrypt the message using their public key and send it to them. They would then use their private key to decrypt the message.
