Detailed explanation-1: -Public key encryption uses two different keys. One key is used to encrypt the information and the other is used to decrypt the information. Sometimes this is referred to as asymmetric encryption because two keys are required to make the system and/or process work securely.

Detailed explanation-2: -What is asymmetric encryption? Asymmetric encryption uses the notion of a key pair: a different key is used for the encryption and decryption process. One of the keys is typically known as the private key and the other is known as the public key.

Detailed explanation-3: -Asymmetric cryptography, also known as public-key cryptography, is a process that uses a pair of related keys–one public key and one private key–to encrypt and decrypt a message and protect it from unauthorized access or use.

Detailed explanation-4: -Public key cryptography involves a pair of keys known as a public key and a private key (a public key pair), which are associated with an entity that needs to authenticate its identity electronically or to sign or encrypt data. Each public key is published and the corresponding private key is kept secret.
