FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Asymmetric cryptography uses two keys: if you encrypt with one key, you may decrypt with the other. Hashing is a one-way cryptographic transformation using an algorithm (and no key).

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 encryption, also known as public key encryption, uses a public key-private key pairing: data encrypted with the public key can only be decrypted with the private key.

Detailed explanation-4: -The main difference between asymmetric versus symmetric cryptography is that asymmetric encryption algorithms make use of two different but related keys. One key encrypts data and another key decrypts it. Symmetric encryption uses the same key to perform both encryption and decryption functions.

Detailed explanation-5: -Symmetric encryption uses a unique key that must be shared between the people who need to receive the message, while asymmetric encryption uses a pair of public keys and a private key to encrypt and decrypt messages when they are communicated.
