Symmetric Encryption
Symmetric encryption is a type of encryption where the same key is used for both encryption and decryption of data. In this method, the sender and receiver of a message share a secret key that is used to encrypt and decrypt the message. The key is kept secret from anyone who should not have access to the data. Symmetric encryption is a fast and efficient way to encrypt large amounts of data, making it a popular choice for securing data in transit or at rest. However, the security of symmetric encryption depends on the security of the key, which can be compromised if it falls into the wrong hands.
