Detailed Description

Message authentication code provider.

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

aes-cmac.cpp.


Constructor & Destructor Documentation

QCA::MACContext::MACContext ( Provider p,
const QString type 
) [inline]

Standard constructor.

Parameters:
p the provider associated with this context
type the name of the type of MAC algorithm provided by this context


Member Function Documentation

Returns the KeyLength for this MAC algorithm.

virtual void QCA::MACContext::setup ( const SymmetricKey key  )  [pure virtual]

Set up the object for hashing.

Parameters:
key the key to use with the MAC.

virtual void QCA::MACContext::update ( const MemoryRegion in  )  [pure virtual]

Process a chunk of data.
