Answer 2

The public and private key pair comprise of a uniquely related cryptographic keys (basically long random numbers). In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt. Security depends on the secrecy of the private key.
