Up to now I have the code below which I borrowed from Firefox to do
the conversion. I hope it works for me, I will let everybody know
later.
My ultimate goal is to extract the value of one of the X509 extensions
of the certificate (SUBJECT ALT NAME). nsIX509Cert does not seem to
have a way to do this. Can somebody please correct me if I am wrong?
Is there any way to extract the X509 extension's value from a
nsIX509Cert object without converting to CERTCertificate first?
Thanks
/////////////////////////////////////////////////////////////////
// certToShow is nsIX509Cert
SECItem der;
CERTCertificate *peerCert
rv=certToShow->GetRawDER(&der.len, (PRUint8 **)&der.data);
if (NS_FAILED(rv))
return rv;
CERTCertificate *tmpCert;
CERTCertDBHandle *certdb = CERT_GetDefaultCertDB();
tmpCert = CERT_FindCertByDERCert(certdb, &der);
if (!tmpCert)
{
tmpCert = CERT_NewTempCertificate(certdb, &der, nsnull,
PR_FALSE,
PR_TRUE);
}
nsMemory::Free(der.data);
der.data = nsnull;
der.len = 0;
if (!tmpCert) {
NS_ERROR("Couldn't create cert from DER blob\n");
return NS_ERROR_FAILURE;
}
