Member Function Documentation

endorsements_fetching_status()

FetchStatus ccf::NetworkIdentitySubsystem::endorsements_fetching_status ( ) const

inlineoverridevirtual

Returns the current status of endorsement fetching.

Implements ccf::NetworkIdentitySubsystemInterface.

get()

const std::unique_ptr< NetworkIdentity > & ccf::NetworkIdentitySubsystem::get ( )

inlineoverridevirtual

Returns a reference to the current network identity.

Implements ccf::NetworkIdentitySubsystemInterface.

get_cose_endorsements_chain()

std::optional< CoseEndorsementsChain > ccf::NetworkIdentitySubsystem::get_cose_endorsements_chain ( ccf::SeqNo  seqno ) const

inlineoverridevirtual

Returns the COSE endorsements chain for the given sequence number, or std::nullopt if the chain is not available for the given sequence number.

Exceptions

IdentityHistoryNotFetched

if identity history fetching has not completed.

Implements ccf::NetworkIdentitySubsystemInterface.

get_trusted_identity_for()

ccf::crypto::ECPublicKeyPtr ccf::NetworkIdentitySubsystem::get_trusted_identity_for ( ccf::SeqNo  seqno ) const

inlineoverridevirtual

Returns the trusted EC public key that was active at the given sequence number, or nullptr if the sequence number precedes the earliest known trusted key.

Exceptions

IdentityHistoryNotFetched	if identity history fetching has not completed.
std::logic_error	if no trusted keys have been fetched, or if internal key resolution is inconsistent.

Implements ccf::NetworkIdentitySubsystemInterface.

get_trusted_keys()

TrustedKeys ccf::NetworkIdentitySubsystem::get_trusted_keys ( ) const

inlineoverridevirtual

Returns all trusted network identity keys as a map from sequence number to EC public key.

Exceptions

IdentityHistoryNotFetched

if identity history fetching has not completed.

Implements ccf::NetworkIdentitySubsystemInterface.
