Detailed explanation-3: -The two types of data encryption methods are Symmetric Encryption and Asymmetric Encryption. Symmetric encryption is also known as private-key cryptography or secret key algorithm and requires both the parties of sender and receiver to have access to the same key to decrypt the data.
