Cryptography symmetric and asymmetric
WebNov 18, 2024 · Symmetric encryption and asymmetric encryption are performed using different processes. Symmetric encryption is performed on streams and is therefore useful to encrypt large amounts of data. Asymmetric encryption is performed on a small number of bytes and is therefore useful only for small amounts of data. Symmetric encryption WebJun 15, 2024 · 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. Symmetric encryption is an old technique, while asymmetric encryption is relatively new.
