Widely used symmetric encryption algorithms include AES-128, AES-192, and AES-256.The host in the communication process would have received the key through external means. The plaintext is encrypted using a key, and the same key is used at the receiving end to decrypt the received ciphertext.Because the algorithm behind symmetric encryption is less complex and executes faster, this is the preferred technique when transmitting data in bulk.As discussed already, it uses one key for both encryption and decryption. This is said to be the simplest and best-known encryption technique. Let’s explore each of these encryption methods separately to understand their differences better. The basic difference between these two types of encryption is that symmetric encryption uses one key for both encryption and decryption, and the asymmetric encryption uses public key for encryption and a private key for decryption. Two common encryption types are the symmetric and asymmetric encryption.Encryption is the process of scrambling data to make sure unintended recipients are not able to make any sense of the data.
