Explanation:
Detailed explanation-1: -Asymmetric cryptography offers better security because it uses two different keys-a public key which only gets used to encrypt messages, making it safe for anyone to have, and a private key to decrypt messages that never needs to be shared.
Detailed explanation-2: -Decryption is the process of converting ciphertext back to plaintext. To encrypt more than a small amount of data, symmetric encryption is used. A symmetric key is used during both the encryption and decryption processes.
