In order for two parties to communicate confidentially, they must first exchange the secret key that will be used to encrypt and decrypt messages. This initial exchange the encryption key is … WebCryptography confirms accountability and responsibility from the sender of a message, which means they cannot later deny their intentions when they created or transmitted information. Digital signatures are a good example of this, as they ensure a sender cannot claim a message, contract, or document they created to be fraudulent.
