Symmetric Key Encryption
Symmetric Key Encryption is a type of encryption where the same secret key is used for both encryption and decryption of data. In this method, the sender and receiver both use the same key to encrypt and decrypt the message. The key is kept secret and secure to prevent unauthorized access to the data. Symmetric Key Encryption is a fast and efficient method of encryption, making it ideal for encrypting large amounts of data. However, the main disadvantage of this method is that if the key is compromised, all the data encrypted with that key can be easily decrypted. Therefore, it is important to keep the key secure and change it regularly to maintain the security of the data.
