    44     \class QSslCertificate

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

    46     \since 4.3

    47 

    48     \reentrant

    49     \ingroup network

    50     \ingroup ssl

    51     \inmodule QtNetwork

    52 

    53     QSslCertificate stores an X509 certificate, and is commonly used

    54     to verify the identity and store information about the local host,

    55     a remotely connected peer, or a trusted third party Certificate

    56     Authority.

    57 

    58     There are many ways to construct a QSslCertificate. The most

    59     common way is to call QSslSocket::peerCertificate(), which returns

    60     a QSslCertificate object, or QSslSocket::peerCertificateChain(),

    61     which returns a list of them. You can also load certificates from

    62     a DER (binary) or PEM (Base64) encoded bundle, typically stored as

    63     one or more local files, or in a Qt Resource.

    64 

    65     You can call isNull() to check if your certificate is null. By

    66     default, QSslCertificate constructs a null certificate. To check

    67     if the certificate is valid, call isValid(). A null certificate is

    68     invalid, but an invalid certificate is not necessarily null. If

    69     you want to reset all contents in a certificate, call clear().

    70 

    71     After loading a certificate, you can find information about the

    72     certificate, its subject, and its issuer, by calling one of the

    73     many accessor functions, including version(), serialNumber(),

    74     issuerInfo() and subjectInfo(). You can call effectiveDate() and

    75     expiryDate() to check when the certificate starts being

    76     effective and when it expires.

    77     The publicKey() function returns the certificate

    78     subject's public key as a QSslKey. You can call issuerInfo() or

    79     subjectInfo() to get detailed information about the certificate

    80     issuer and its subject.

    81 

    82     Internally, QSslCertificate is stored as an X509 structure. You

    83     can access this handle by calling handle(), but the results are

    84     likely to not be portable.

    85

    90     \enum QSslCertificate::SubjectInfo

    91 

    92     Describes keys that you can pass to QSslCertificate::issuerInfo() or

    93     QSslCertificate::subjectInfo() to get information about the certificate

    94     issuer or subject.

    95 

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

    97 

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

    99     the host name.

   103     \value OrganizationalUnitName "OU" The organizational unit name.
