### Symmetric and Asymmetric Encryption

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.

In a symmetric-key algorithm the key used to encrypt is the same as the one used to decrypt. For this reason, it needs to be kept secret. (Above)
