CTConfig is the top-level config object expected to be embedded in an executable's JSON config struct.

CTGroup represents a group of CT Logs.

LogDescription contains the information needed to submit certificates to a CT log and verify returned receipts.

LogID holds enough information to uniquely identify a CT Log: its log_id (the base64-encoding of the SHA-256 hash of its public key) and its human- readable name/description.

LogShard describes a single shard of a temporally sharded CT log.

TemporalSet contains a set of temporal shards of a single log.
