COMPUTER FUNDAMENTALS

Detailed explanation-1: -Public keys have been described by some as being like a business’ address on the web – it’s public and anyone can look it up and share it widely. In asymmetric encryption, public keys can be shared with everyone in the system. Once the sender has the public key, he uses it to encrypt his message.

Detailed explanation-2: -A public key is a cryptographic key that can be used by any person to encrypt a message so that it can only be decrypted by the intended recipient with their private key. A private key–also known as a secret key–is shared only with key’s initiator.

Detailed explanation-3: -Public key encryption One key is nominated as the private key and is kept secret. The other key is distributed to anyone who wants it; this key is the public key. Anyone can encrypt a message by using your public key, but only you can read it. When you receive the message, you decrypt it by using your private key.

Detailed explanation-4: -Explanation: In public-key (also known as asymmetric-key) encryption techniques, there are two different keys, the public key and the private key, used to encrypt and decrypt the data. Explanation: This happens when particularly if the encryption key is publicly available.
