    \class QSslCertificate
    \brief The QSslCertificate class provides a convenient API for an X509 certificate.
    \since 4.3

    \reentrant
    \ingroup network
    \ingroup ssl
    \ingroup shared
    \inmodule QtNetwork

    QSslCertificate stores an X509 certificate, and is commonly used
    to verify the identity and store information about the local host,
    a remotely connected peer, or a trusted third party Certificate
    Authority.

    There are many ways to construct a QSslCertificate. The most
    common way is to call QSslSocket::peerCertificate(), which returns
    a QSslCertificate object, or QSslSocket::peerCertificateChain(),
    which returns a list of them. You can also load certificates from
    a DER (binary) or PEM (Base64) encoded bundle, typically stored as
    one or more local files, or in a Qt Resource.

    You can call isNull() to check if your certificate is null. By default,
    QSslCertificate constructs a null certificate. A null certificate is
    invalid, but an invalid certificate is not necessarily null. If you want
    to reset all contents in a certificate, call clear().

    After loading a certificate, you can find information about the
    certificate, its subject, and its issuer, by calling one of the
    many accessor functions, including version(), serialNumber(),
    issuerInfo() and subjectInfo(). You can call effectiveDate() and
    expiryDate() to check when the certificate starts being
    effective and when it expires.
    The publicKey() function returns the certificate
    subject's public key as a QSslKey. You can call issuerInfo() or
    subjectInfo() to get detailed information about the certificate
    issuer and its subject.

    Internally, QSslCertificate is stored as an X509 structure. You
    can access this handle by calling handle(), but the results are
    likely to not be portable.

    \sa QSslSocket, QSslKey, QSslCipher, QSslError
*/

/*!
    \enum QSslCertificate::SubjectInfo

    Describes keys that you can pass to QSslCertificate::issuerInfo() or
    QSslCertificate::subjectInfo() to get information about the certificate
    issuer or subject.

    \value Organization "O" The name of the organization.

    \value CommonName "CN" The common name; most often this is used to store
    the host name.

    \value LocalityName "L" The locality.

    \value OrganizationalUnitName "OU" The organizational unit name.

    \value CountryName "C" The country.

    \value StateOrProvinceName "ST" The state or province.

    \value DistinguishedNameQualifier The distinguished name qualifier

    \value SerialNumber The certificate's serial number

    \value EmailAddress The email address associated with the certificate
