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

MACContext()

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

References QCA::BasicContext::BasicContext(), and QCA::Provider::Context::type().

Member Function Documentation

setup()

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.

Examples

aes-cmac.cpp.

keyLength()

virtual KeyLength QCA::MACContext::keyLength ( ) const

pure virtual

Returns the KeyLength for this MAC algorithm.

Examples

aes-cmac.cpp.

update()

virtual void QCA::MACContext::update ( const MemoryRegion & in )

pure virtual

Process a chunk of data.

Parameters

in	the input data to process

Examples

aes-cmac.cpp.

final()

virtual void QCA::MACContext::final ( MemoryRegion * out )

pure virtual

Compute the result after processing all data.

Parameters

out	pointer to an array that should store the result

anyKeyLength()

KeyLength QCA::MACContext::anyKeyLength ( ) const

inlineprotected

Returns a KeyLength that supports any length.
