WebNov 30, 2024 · Public Key Cryptography is a type of cryptography that uses pairs of keys. In this system, one key is public, meaning that it can be known by anyone. The second key is the private key, and it is known only by the owner. In this system, a person uses the public key to encrypt a message. That message is then decrypted by the private key. the pilgrims came to america in
