QSslKey Class

Member Function Documentation

QSslKey::QSslKey(const QSslKey &other)

Constructs an identical copy of other.

QSslKey::QSslKey(Qt::HANDLE handle, QSsl::KeyType type = QSsl::PrivateKey)

Constructs a QSslKey from a valid native key handle. type specifies whether the key is public or private.

QSslKey will take ownership for this key and you must not free the key using the native library.

This function was introduced in Qt 5.0.

QSslKey::QSslKey(QIODevice *device, QSsl::KeyAlgorithm algorithm, QSsl::EncodingFormat encoding = QSsl::Pem, QSsl::KeyType type = QSsl::PrivateKey, const QByteArray &passPhrase = QByteArray())

Constructs a QSslKey by reading and decoding data from a device using a specified algorithm and encoding format. type specifies whether the key is public or private.

If the key is encrypted then passPhrase is used to decrypt it.

After construction, use isNull() to check if device provided a valid key.

QSslKey::QSslKey(const QByteArray &encoded, QSsl::KeyAlgorithm algorithm, QSsl::EncodingFormat encoding = QSsl::Pem, QSsl::KeyType type = QSsl::PrivateKey, const QByteArray &passPhrase = QByteArray())

Constructs a QSslKey by decoding the string in the byte array encoded using a specified algorithm and encoding format. type specifies whether the key is public or private.

If the key is encrypted then passPhrase is used to decrypt it.

After construction, use isNull() to check if encoded contained a valid key.

QSslKey::QSslKey()

Constructs a null key.

See also isNull().

QSslKey &QSslKey::operator=(const QSslKey &other)

Copies the contents of other into this key, making the two keys identical.

Returns a reference to this QSslKey.

QSslKey::~QSslKey()

Destroys the QSslKey object.

QSsl::KeyAlgorithm QSslKey::algorithm() const

Returns the key algorithm.

void QSslKey::clear()

Clears the contents of this key, making it a null key.

See also isNull().

Qt::HANDLE QSslKey::handle() const

Returns a pointer to the native key handle, if there is one, else nullptr.

You can use this handle together with the native API to access extended information about the key.

bool QSslKey::isNull() const

Returns true if this is a null key; otherwise false.

See also clear().

int QSslKey::length() const

Returns the length of the key in bits, or -1 if the key is null.

void QSslKey::swap(QSslKey &other)

Swaps this ssl key with other. This function is very fast and never fails.

This function was introduced in Qt 5.0.

QByteArray QSslKey::toDer(const QByteArray &passPhrase = QByteArray()) const

Returns the key in DER encoding.

The passPhrase argument should be omitted as DER cannot be encrypted. It will be removed in a future version of Qt.

QByteArray QSslKey::toPem(const QByteArray &passPhrase = QByteArray()) const

Returns the key in PEM encoding. The result is encrypted with passPhrase if the key is a private key and passPhrase is non-empty.

QSsl::KeyType QSslKey::type() const

Returns the type of the key (i.e., PublicKey or PrivateKey).

bool QSslKey::operator!=(const QSslKey &other) const

Returns true if this key is not equal to key other; otherwise returns false.

bool QSslKey::operator==(const QSslKey &other) const

Returns true if this key is equal to other; otherwise returns false.
