The true statement concerning the public key on your CAC?

The public key on your Common Access Card (CAC) is used to facilitate secure communication and authentication. It is part of a key pair, with the corresponding private key stored securely on the card itself. This public key can be shared freely and is used to encrypt messages or verify digital signatures, ensuring that only the holder of the corresponding private key can decrypt the information or sign documents securely. Overall, it plays a critical role in maintaining the security and integrity of digital transactions and communications.
