This is the SHA-256 of the certificate file exactly as it was issued. Run the command against the file you were sent: if the two strings match, your copy is byte for byte the one this laboratory issued.
A copy that has been re-saved, printed to a new file or passed through a converter will not match, because each of those produces a different file. Compare the certificate exactly as it was sent to you, or the copy downloadable from this page.
