Excuse me, I'm a bit confused about the differences between digital signatures and key exchange. Could you clarify if they are indeed the same? My understanding is that digital signatures are used to authenticate the sender of a message and ensure its integrity, while key exchange is a process of securely sharing cryptographic keys between two parties. Do they overlap in functionality or are they completely separate concepts? It seems like they might be related but I'm not entirely sure. Could you elaborate on the key distinctions between the two?

During this process, the private key of one party is used to decrypt an encrypted symmetric key, which was originally encrypted using the corresponding public key of the other party.

Unlike key exchange, digital signatures primarily leverage the public key for the purpose of authenticating messages.

In the context of digital signatures, the sender utilizes their private key to generate a signature appended to the message.

The recipient, in turn, utilizes the sender's publicly available public key to verify the authenticity of the signature and, consequently, the integrity of the message.
