Explanation:
Detailed explanation-1: -The two keys are called the “public key” and the “private key” of the user. The network also has a public key and a private key. The sender uses a public key to encrypt the message. The recipient uses its private key to decrypt the message.
Detailed explanation-2: -In asymmetric, or public key, encryption, there are two keys: one key is used for encryption, and a different key is used for decryption. The decryption key is kept private (hence the “private key” name), while the encryption key is shared publicly, for anyone to use (hence the “public key” name).
