This sharing can be done via asymmetric encryption. +- To use a symmetric encryption scheme, the sender and receiver must securely share a key in advance. This sharing can be done via asymmetric encryption or established through a key exchange algorithm like [Diffie Hellman key exchange](https://en.wikipedia.org/wiki/Diffie%E2%80%93Hellman_key_exchange). #### Asymmetric Encryption
