• [nitpick] Error messages should follow the project’s style by omitting terminal punctuation and using sentence case; consider removing the trailing periods and adjusting to a single coherent sentence, e.g.: Unable to decode client's signature; please check the message format.

InvalidSignatureFormat   = "Unable to decode client's signature. Please check the message's format."
