Detailed Description

Fetch certificate bundle from the network.

Currently bundle fetching is attempted only for Data validation. This may change in the future. Bundle fetching always goes to the infrastructure regardless of the inner fetcher. Inner fetcher is used when the bundle interest times out or returns a Nack or when additional certificates are needed for validation.

inherited

Asynchronously fetch certificate.

Precondition: m_certStorage != nullptr

If the requested certificate exists in the storage, then this method will immediately call continueValidation with the certification. If certificate is not available, the implementation-specific doFetch will be called to asynchronously fetch certificate. The successfully retrieved certificate will be automatically added to the unverified cache of the certificate storage.

When the requested certificate is retrieved, continueValidation is called. Otherwise, the fetcher implementation call state->failed() with the appropriate error code and diagnostic message.
