What type of information can be found in an X.509 Digital Certificate?

An X.509 Digital Certificate serves as a critical component in establishing secure communications and identity verification in digital environments. The correct answer highlights the essential elements found in such a certificate.

An X.509 Digital Certificate typically includes the owner's Common Name (often the fully qualified domain name for a website), the asymmetric public key used in cryptographic operations, and the Certificate Authority's (CA's) digital signature. These components work together to authenticate the identity of the owner and ensure that the public key can indeed be trusted, as it has been verified by a reputable CA.

The presence of the owner’s Common Name helps in confirming that the certificate is valid for that specific entity, while the public key is necessary for asymmetrical encryption processes. The CA's digital signature provides a layer of trust, confirming that the certificate has not been tampered with and that the information contained within it is legitimate and validated by the issuing authority. This structure is vital for enabling secure exchanges of information over networks.

Options that suggest including a person's birth date or symmetric keys are not relevant to the X.509 standard. Additionally, items like server IP addresses or certificate expiration details, while potentially associated with SSL/TLS agreements or protocols, miss the core elements defined by X.509 specifications
