What is contained in a public certificate?

• A. Public key
• B. The certificate issuer
• C. Public key, Organization details, and the certificate issuer
• D. Private key

Answer: (C)

Public certificates are used to bind a public key to an entity and prove it was issued by a trusted authority. They contain the public key, the subject’s identity (organization details), and the issuer’s information (the certificate authority). They may also include other data like validity period and the issuer’s digital signature, but they never include the private key. That’s why the option that lists the public key, organization details, and the certificate issuer best matches what a public certificate contains. The private key is intentionally kept secret and is not part of the certificate. Options that include only the public key or only the issuer miss essential pieces, and the private key option is incorrect for that reason.
