## Detailed Description

It holds information such as client identity, pre shared key, information about certificates, and so on.

## Member Function Documentation

### QCoapSecurityConfiguration::QCoapSecurityConfiguration(QCoapSecurityConfiguration &&other)

Move-constructs a QCoapSecurityConfiguration, making it point to the same object as other was pointing to.

### QCoapSecurityConfiguration::QCoapSecurityConfiguration(const QCoapSecurityConfiguration &other)

Copies the configuration and state of other.

### QCoapSecurityConfiguration::QCoapSecurityConfiguration()

Constructs a new QCoapSecurityConfiguration.

### QCoapSecurityConfiguration &QCoapSecurityConfiguration::operator=(const QCoapSecurityConfiguration &other)

Copies the configuration and state of other.

### QCoapSecurityConfiguration::~QCoapSecurityConfiguration()

Releases any resources held by QCoapSecurityConfiguration.

### QList<QSslCertificate> QCoapSecurityConfiguration::caCertificates() const

Returns this connection's certificate authority certificate database.

See also setCaCertificates().

### QString QCoapSecurityConfiguration::defaultCipherString() const

Returns the default cipher string.

See also setDefaultCipherString().

### QList<QSslCertificate> QCoapSecurityConfiguration::localCertificateChain() const

Returns the certificate chain to be presented to the peer during the handshake.

See also setLocalCertificateChain().

### QByteArray QCoapSecurityConfiguration::preSharedKey() const

Returns the pre shared key.

See also setPreSharedKey().

### QByteArray QCoapSecurityConfiguration::preSharedKeyIdentity() const

Returns the PSK client identity.

See also setPreSharedKeyIdentity().

### QCoapPrivateKey QCoapSecurityConfiguration::privateKey() const

Returns the private key assigned to the connection.

See also setPrivateKey() and localCertificateChain().

### void QCoapSecurityConfiguration::setCaCertificates(const QList<QSslCertificate> &certificates)

Sets certificates as the certificate authority database for the connection.

See also caCertificates().

### void QCoapSecurityConfiguration::setDefaultCipherString(const QString &cipherString)

Sets the SSL cipher string to cipherString.

The security back-end (for example OpenSSL) might not include ciphers required for RFC 7252 by default. This method specifies which ciphers the back-end should use. For example to enable CCM ciphers required by RFC, "AESCCM" can be passed as cipherString.

See the OpenSSL docs for more information about cipher strings.

See also defaultCipherString().

### void QCoapSecurityConfiguration::setLocalCertificateChain(const QList<QSslCertificate> &localChain)

Sets localChain as the certificate chain to present to the peer during the handshake.

See also localCertificateChain().

### void QCoapSecurityConfiguration::setPreSharedKey(const QByteArray &preSharedKey)

Sets the pre shared key to preSharedKey.

See also preSharedKey().

### void QCoapSecurityConfiguration::setPreSharedKeyIdentity(const QByteArray &identity)

Sets the PSK client identity (to be advised to the server) to identity.

See also preSharedKeyIdentity().

### void QCoapSecurityConfiguration::setPrivateKey(const QCoapPrivateKey &key)

Sets the connection's private key to key.

See also privateKey() and setLocalCertificateChain().

### void QCoapSecurityConfiguration::swap(QCoapSecurityConfiguration &other)

Swaps this security configuration with other. This operation is very fast and never fails.
