Question: 1 / 545

What attribute of a digital certificate specifies the hash value for verifying the certificate's integrity?

Serial number

Thumbprint

The thumbprint attribute of a digital certificate is crucial for verifying the certificate's integrity, as it provides a unique hash value generated from the certificate's contents. This hash value acts as a digital fingerprint, ensuring that any alterations to the certificate can be detected. If the contents of the certificate are modified in any way, the hash will change, thus failing verification when compared to the original thumbprint value.

In digital certificates, the thumbprint is typically created using a hashing algorithm such as SHA-1 or SHA-256. This means that the thumbprint provides an efficient way to confirm that the certificate being presented has not been tampered with and truly belongs to the entity it claims to represent, thereby playing a critical role in maintaining the security and trustworthiness of digital communications.
