Whenever a copy of a writing is certified for the purpose of being offered in evidence before any court or any officer, board, or tribunal, the certificate must state in substance that the copy is a correct copy of the original, or of a specified part thereof, as the case may be. The certificate must be under the official seal of the certifying officer, if there be any, or if he be the clerk of a court having a seal, under the seal of such court.
