Detailed explanation-1: -An encryption key is typically a random string of bits generated specifically to scramble and unscramble data. Encryption keys are created with algorithms designed to ensure that each key is unique and unpredictable. The longer the key constructed this way, the harder it is to break the encryption code.
Detailed explanation-2: -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-3: -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).
