\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.

/*!
\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
*/
/*!
\enum QSslCertificate::PatternSyntax
\since 5.15
The syntax used to interpret the meaning of the pattern.
\value RegularExpression A rich Perl-like pattern matching syntax.
\value Wildcard This provides a simple pattern matching syntax
similar to that used by shells (command interpreters) for "file
globbing". See \l {QRegularExpression::fromWildcard()}.
\value FixedString The pattern is a fixed string. This is
equivalent to using the RegularExpression pattern on a string in
which all metacharacters are escaped using escape(). This is the
default.
