> The {{BlackListBasedTrustedChannelResolver}} class is responsible for setting server and client blacklists based on configuration settings. However, the current implementation lacks sufficient logging, making it difficult to trace which configuration is applied during runtime. This enhancement proposes to add logging to the {{setConf}} method to better expose the relationship between configuration settings and their applied behavior.
>
> *Expected Behavior:*
> The system should log specific information about whether the server or client variable blacklist is enabled and which file and expiry time are being used. This will aid in debugging and monitoring the configuration settings applied during the system's operation.
>
> *How-to-Fix:*
> We propose to expose the relationship between the configuration settings and the applied behavior by adding logs in the {{setConf}} method.
