It is OK for a verifier to receive digital certificates from the sender.

• A. True
• B. False
• C. Not sure
• D. Both True and False

Answer: (A)

Digital certificates are meant to be shared with verifiers. A certificate ties a public key to a known identity and is signed by a trusted authority, allowing the verifier to trust the public key without exposing any private material. When the sender provides a certificate, the verifier can use the included public key to check a signature or to establish an encrypted channel, after validating the certificate’s chain, validity period, and revocation status. Importantly, sending the certificate does not reveal the private key, so distribution of the certificate is safe and expected.
