chromeos/network/network_certificate_handler.cc has this code:
28 std::string alt_text;
29 if (!cert.subject().organization_names.empty())
30 alt_text = cert.subject().organization_names[0];
31 if (alt_text.empty())
32 alt_text = cert.subject().GetDisplayName();
33 result.issued_by =
34 certificate::GetIssuerCommonName(cert.os_cert_handle(), alt_text);
data from the certificate subject is being used as the alt text if the issuer commonName is empty. I guess that should be issuer() in the above code?
