On Github's certificate the strings for certificate-viewer-business-category, certificate-viewer-inc.-country and certificate-viewer-inc.-state-/-province seem to be missing.

There are other translations missing (certificate-viewer-not-before-utc, certificate-viewer-not-after-utc, certificate-viewer-timestamputc) but I'm not sure if they'll be display (we added them because was easier for testing)
