### QMultiMap<QSsl::AlternateNameEntryType, QString> QSslCertificate::alternateSubjectNames() const

Use QSslCertificate::subjectAlternativeNames();

### bool QSslCertificate::isValid() const

To verify a certificate, use verify(). To check if a certificate is blacklisted, use isBlacklisted(). To check if a certificate has expired or is not yet valid, compare expiryDate() and effectiveDate() with QDateTime::currentDateTime()

This function checks that the current date-time is within the date-time range during which the certificate is considered valid, and checks that the certificate is not in a blacklist of fraudulent certificates.
