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
pthe provider associated with this context
typethe name of the type of MAC algorithm provided by this context

Member Function Documentation

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

Set up the object for hashing.

Parameters
keythe key to use with the MAC.
Examples:
aes-cmac.cpp.
virtual KeyLength QCA::MACContext::keyLength ( ) const
pure virtual

Returns the KeyLength for this MAC algorithm.

Examples:
aes-cmac.cpp.
virtual void QCA::MACContext::update ( const MemoryRegion in)
pure virtual

Process a chunk of data.

Parameters
inthe input data to process
Examples:
aes-cmac.cpp.
virtual void QCA::MACContext::final ( MemoryRegion out)
pure virtual

Compute the result after processing all data.

Parameters
outpointer to an array that should store the result
KeyLength QCA::MACContext::anyKeyLength ( ) const
inlineprotected

Returns a KeyLength that supports any length.
