Detailed Description

SecureMessage provider.

Note: This class is part of the provider plugin interface and should not be used directly by applications. You probably want SecureMessage instead.

Member Enumeration Documentation

◆ Operation

enum QCA::MessageContext::Operation

The type of operation being performed.

Enumerator
Encrypt	Encrypt operation.
Decrypt	Decrypt (or Decrypt and Verify) operation.
Sign	Sign operation.
Verify	Verify operation.
SignAndEncrypt	Sign and Encrypt operation.

Definition at line 2919 of file qcaprovider.h.

Constructor & Destructor Documentation

◆ MessageContext()

QCA::MessageContext::MessageContext	(	Provider *	p,
		const QString &	type )

inline

Standard constructor.

Parameters

p	the Provider associated with this context
type	the name of the type of secure message to be created

Definition at line 2934 of file qcaprovider.h.

Member Function Documentation

◆ canSignMultiple()

virtual bool QCA::MessageContext::canSignMultiple ( ) const

pure virtual

Returns true if the provider supports multiple signers for signature creation or signature verification.

◆ diagnosticText()

virtual QString QCA::MessageContext::diagnosticText ( ) const

virtual

Returns any diagnostic text for the operation, potentially useful to show the user in the event the operation is unsuccessful.

For example, this could be the stderr output of gpg.

This is only valid if the operation has finished.

◆ end()

virtual void QCA::MessageContext::end ( )

pure virtual

Indicates the end of input.

◆ errorCode()

virtual SecureMessage::Error QCA::MessageContext::errorCode ( ) const

pure virtual

Returns the reason for failure, if the operation was not successful.

This is only valid if the operation has finished.

◆ finished()

virtual bool QCA::MessageContext::finished ( ) const

pure virtual

Returns true if the operation has finished, otherwise false.

◆ hashName()

virtual QString QCA::MessageContext::hashName ( ) const

pure virtual

Returns the name of the hash used to generate the signature, in the case of a signature operation.

This is only valid if the operation has finished.

◆ read()

virtual QByteArray QCA::MessageContext::read ( )

pure virtual

Extract output from the message operation.

◆ reset()

virtual void QCA::MessageContext::reset ( )

pure virtual

Reset the object to its initial state.

◆ setupEncrypt()

virtual void QCA::MessageContext::setupEncrypt ( const SecureMessageKeyList & keys )

pure virtual

Configure a new encrypting operation.

Parameters

keys	the keys to be used for encryption.

◆ setupSign()

virtual void QCA::MessageContext::setupSign	(	const SecureMessageKeyList &	keys,
		SecureMessage::SignMode	m,
		bool	bundleSigner,
		bool	smime )

pure virtual

Configure a new signing operation.

Parameters

keys	the keys to use for signing
m	the mode to sign in
bundleSigner	whether to bundle the signing keys (true) or not (false)
smime	whether to use smime format (true) or not (false)

◆ setupVerify()

virtual void QCA::MessageContext::setupVerify ( const QByteArray & detachedSig )

pure virtual

Configure a new verify operation.

Parameters

detachedSig the detached signature to use (if applicable) for verification

◆ signature()

virtual QByteArray QCA::MessageContext::signature ( ) const

pure virtual

Returns the signature, in the case of a detached signature operation.

This is only valid if the operation has finished.

◆ signers()

virtual SecureMessageSignatureList QCA::MessageContext::signers ( ) const

pure virtual

Returns a list of signatures, in the case of a verify or decrypt and verify operation.

This is only valid if the operation has finished.

◆ start()

virtual void QCA::MessageContext::start	(	SecureMessage::Format	f,
		Operation	op )

pure virtual

Begins the secure message operation.

This function returns immediately.

If there is input data, update() will be called (potentially repeatedly) afterwards. Emit updated() if there is data to read, if input data has been accepted, or if the operation has finished.

Parameters

f	the format of the message to be produced
op	the operation to be performed

◆ success()

virtual bool QCA::MessageContext::success ( ) const

pure virtual

Returns true if the operation was successful.

This is only valid if the operation has finished.

◆ type()

virtual SecureMessage::Type QCA::MessageContext::type ( ) const

pure virtual

The type of secure message (e.g.

PGP or CMS)

◆ update()

virtual void QCA::MessageContext::update ( const QByteArray & in )

pure virtual

Provide input to the message operation.

Parameters

in	the data to use for the message operation

◆ updated

void QCA::MessageContext::updated ( )

signal

Emitted when there is data to read, if input data has been accepted, or if the operation has finished.

◆ waitForFinished()

virtual bool QCA::MessageContext::waitForFinished ( int msecs )

pure virtual

Waits for the secure message operation to complete.

In this case, the updated() signal is not emitted. Returns true if the operation completed or false if this function times out.

This function is blocking.

Parameters

msecs number of milliseconds to wait (-1 to wait forever)

◆ written()

virtual int QCA::MessageContext::written ( )

pure virtual

Returns the number of input bytes accepted since the last call to update()
