Answer #1

Public Key Cryptography is also known as "Asymmetric Encryption", which uses two mathematically related, but unique keys known as public key and private key.

A message is encrypted using public key, can be decrypted only with the corresponding private key and a message encrypted with private key, can only be decrypted with the corresponding public key.

It is not possible to generate the private key using public key, because of this public key is freely available to the users.But the private key is kept confidential.

For example, User A wants to send confidential data to User B, User A encrypt the data with the User B's public key, which is freely available, and send it to the User B. User B recieves the encrypted data and decrypt the data with his/her private key, which is only known to User B.

Therefore, Public key cryptography leverages two different keys is TRUE.
