As well as the main distributed CT Log implementation, this repository also contains code for a mirror Log. A mirror Log tracks an underlying Log elsewhere, and so does not allow certificate upload. The mirror Log is a distributed implementation like the main Log, and so can act as a more scalable 'front-end' for another Log.
The core executable for the mirror Log is cpp/server/ct-mirror, and it
generally needs the same
configuration and setup as the main
Log. The required additional configuration options for a mirror Log are:
--target_log_uri=<url>specifies the URL of the target Log to be mirrored.--target_public_key=<pemfile>specifies the public key of the target Log. (For public Logs tracked by Chrome, public keys are available for download from the Known Logs page.)
