The statement that is always true regarding the use of encryption algorithms based on public key infrastructure (PKI) is: D. The private key uniquely authenticates each party to a transaction. In PKI, each party involved in a transaction possesses a pair of cryptographic keys: a public key and a private key. The private key is kept secret and is known only to the owner, while the public key is freely distributed. The private key uniquely authenticates the party who possesses it, and it is used to decrypt messages that have been encrypted with the corresponding public key.
