◆ clear()

void QTlsPrivate::TlsKeyGeneric::clear ( bool deep )

overridevirtual

Clears the contents of this key, making it a null key. The meaning of deep is implementation-specific (e.g. if some internal objects representing a key can be shared using reference counting, deep equal to true would imply decrementing a reference count).

See also: isNull()

Implements QTlsPrivate::TlsKey.

Here is the call graph for this function:

◆ decodeDer()

void QTlsPrivate::TlsKeyGeneric::decodeDer	(	QSsl::KeyType	type,
		QSsl::KeyAlgorithm	algorithm,
		const QByteArray &	der,
		const QByteArray &	passPhrase,
		bool	deepClear )

overridevirtual

If a support of public and private keys in DER format is required, this function must be overridden and should initialize this key using the type, algorithm, der and passPhrase. If this key was initialized previously, deepClear has an implementation-specific meaning (e.g., if an implementation is using reference-counting and can share internally some data structures, a value true may trigger decrementing a reference counter on some implementation-specific object).

Note: An empty overrider is sufficient, but then reading keys in QSsl::Der format will not be supported.

If a support of public and private keys in PEM format is required, this function must be overridden and should initialize this key using the type, algorithm, pem and passPhrase. If this key was initialized previously, deepClear has an implementation-specific meaning (e.g., in an implementation using reference-counting, a value true may trigger decrementing a reference counter on some implementation-specific object).

◆ derFromPem()

QByteArray QTlsPrivate::TlsKeyGeneric::derFromPem	(	const QByteArray &	pem,
		QMap< QByteArray, QByteArray > *	headers ) const

overridevirtual

Converts pem to DER format, using this key's type and algorithm. The parameter headers must be a valid, non-null pointer. When parsing pem, the headers found there will be saved into headers.

Note: An overrider returning an empty QByteArray is sufficient, if QSslKey::toDer() is not needed.; This function is very implementation-specific. A backend, that already has this key's non-empty DER data, may simply return this data.

Here is the caller graph for this function:

◆ fromHandle()

void QTlsPrivate::TlsKeyGeneric::fromHandle	(	Qt::HANDLE	handle,
		KeyType	type )

overridevirtual

Initializes this key using the handle and type, taking the ownership of the handle.

Note: The meaning of the handle is implementation-specific.; If a TLS backend does not support such keys, it must provide an empty implementation.

◆ handle()

Qt::HANDLE QTlsPrivate::TlsKeyGeneric::handle ( ) const

If a TLS backend supports opaque keys, returns a native handle that this key was initialized with.

◆ isPkcs8()

bool QTlsPrivate::TlsKeyGeneric::isPkcs8 ( ) const

inlineoverridevirtual

This function is internally used only by Qt's own TLS plugins and affects the way PEM file is generated by TlsKey. It's sufficient to override it and return false in case a new TLS backend is not using Qt's plugin as a base.

Reimplemented from QTlsPrivate::TlsKeyBase.

Definition at line 65 of file qtlskey_generic_p.h.

◆ length()

int QTlsPrivate::TlsKeyGeneric::length ( ) const

inlineoverridevirtual

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

Implements QTlsPrivate::TlsKey.

Definition at line 60 of file qtlskey_generic_p.h.

◆ TlsKeyBase()

QTlsPrivate::TlsKeyBase::TlsKeyBase	(	KeyType	type = QSsl::PublicKey,
		KeyAlgorithm	algorithm = QSsl::Opaque )

inline

Definition at line 33 of file qtlskey_base_p.h.

◆ toPem()

QByteArray QTlsPrivate::TlsKeyGeneric::toPem ( const QByteArray & passPhrase ) const

overridevirtual

This function must be overridden, if converting a key to PEM format, potentially with encryption, is needed (e.g. to save a QSslKey into a file). If this key is private and passPhrase is not empty, the key's data is expected to be encrypted using some conventional encryption algorithm (e.g. DES or AES - the one that different tools or even the class QSslKey can understand later).
