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.

Constructor & Destructor Documentation
◆ MessageContext()
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()
|
pure virtual |
Returns true if the provider supports multiple signers for signature creation or signature verification.
◆ diagnosticText()
|
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()
|
pure virtual |
Indicates the end of input.
◆ errorCode()
|
pure virtual |
Returns the reason for failure, if the operation was not successful.
This is only valid if the operation has finished.
◆ finished()
|
pure virtual |
Returns true if the operation has finished, otherwise false.
◆ hashName()
|
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()
|
pure virtual |
Extract output from the message operation.
◆ reset()
|
pure virtual |
Reset the object to its initial state.
◆ setupEncrypt()
|
pure virtual |
Configure a new encrypting operation.
- Parameters
-
keys the keys to be used for encryption.
◆ setupSign()
|
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()
|
pure virtual |
Configure a new verify operation.
- Parameters
-
detachedSig the detached signature to use (if applicable) for verification
◆ signature()
|
pure virtual |
Returns the signature, in the case of a detached signature operation.
This is only valid if the operation has finished.
◆ signers()
|
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()
|
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()
|
pure virtual |
Returns true if the operation was successful.
This is only valid if the operation has finished.
◆ type()
|
pure virtual |
The type of secure message (e.g.
PGP or CMS)
◆ update()
|
pure virtual |
Provide input to the message operation.
- Parameters
-
in the data to use for the message operation
◆ updated
|
signal |
Emitted when there is data to read, if input data has been accepted, or if the operation has finished.
◆ waitForFinished()
|
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()
|
pure virtual |
Returns the number of input bytes accepted since the last call to update()
