I am getting SSL Handshake Errors making a request due to the SAN not being read from the certificate. In the on_SSLErrors, I dump out the peer certificate. using cert.toPem(), I decode it at https://www.sslshopper.com/certificate-decoder.html. This shows the Subject Alternateive Names. But in the cert in QT, I get an empty map from cert.subjectAlternativeNames().

my dumpCert function:

Qt Code: 
  1. void MyRequest::dumpCertificate( const QSslCertificate &cert )
  2.     {
  3.     qDebug() << cert.toPem();
  4.  
  5.     qDebug() << "== Subject Info ==\b";
  6.     qDebug() << "CommonName: " << cert.subjectInfo( QSslCertificate::CommonName );
  7.     qDebug() << "Organization: " << cert.subjectInfo( QSslCertificate::Organization );
  8.     qDebug() << "LocalityName: " << cert.subjectInfo( QSslCertificate::LocalityName );
  9.     qDebug() << "OrganizationalUnitName: " << cert.subjectInfo( QSslCertificate::OrganizationalUnitName );
  10.     qDebug() << "StateOrProvinceName: " << cert.subjectInfo( QSslCertificate::StateOrProvinceName );
  11.  
  12.     QMultiMap<QSsl::AlternativeNameEntryType, QString> altNames = cert.subjectAlternativeNames();
  13.     if ( !altNames.isEmpty() ) {
  14.         qDebug() << "Subject Alternate Names (DNS):";
  15.         foreach (const QString &altName, altNames.values(QSsl::DnsEntry)) {
  16.             qDebug() << altName;
  17.         }
  18.  
  19.         qDebug() << "Alternate Subject Names (Email):";
  20.         foreach (const QString &altName, altNames.values(QSsl::EmailEntry)) {
  21.             qDebug() << altName;
  22.         }
  23.     }
  24.     else {
  25.         qDebug() << "No Subject Alternate Names";
  26.     }
  27.  
  28.  
  29.     qDebug() << "\n== Issuer Info ==";
  30.     qDebug() << "CommonName: " << cert.issuerInfo( QSslCertificate::CommonName );
  31.     qDebug() << "Organization: " << cert.issuerInfo( QSslCertificate::Organization );
  32.     qDebug() << "LocalityName: " << cert.issuerInfo( QSslCertificate::LocalityName );
  33.     qDebug() << "OrganizationalUnitName: " << cert.issuerInfo( QSslCertificate::OrganizationalUnitName );
  34.     qDebug() << "StateOrProvinceName: " << cert.issuerInfo( QSslCertificate::StateOrProvinceName );
  35.  
  36.     qDebug() << "\n== Certificate ==";
  37.     qDebug() << "Serial Number: " << cert.serialNumber(); 
  38.     qDebug() << "Effective Date: " << cert.effectiveDate().toString();
  39.     qDebug() << "Expiry Date: " << cert.expiryDate().toString();
  40.     }
