Shared key (symmetric key)
A synmmetric key is a type of cryptographic key that is used for both encryption and decryption. This means the same key must be securely shared between the sender and the receiver in advance.
It is fast and efficient, especially for encrypting large amounts of data. However, the main challenge is securely distributing the key.
