Please provide two scenarios where asymmetric and symmetric would be used. What advantages does asymmetric encryption have over symmetric encryption? And what advantages does symmetric encryption have over asymmetric encryption?

Uses of asymmetirc ecryption - 

• NIST suggested the digital signatures standard, which is described in FIPS 186-4. Asymmetric cryptography is used to create digital signatures, which provide a layer of validation and security to communications delivered over an insecure channel.
•  Asymmetric encryption is used to initialize the encrypted conversation between two users in messaging applications like WhatsApp and Signal.

Uses of asymmetirc ecryption - 

• For the duration of the transmission after initializing conversation, symmetric encryption is utilised. The specifics may be found in the Whatsapp Encryption Overview White Paper.
• An HTTPS connection between a client and a server, symmetric encryption (called the session) is used for the duration of the connection.
