## 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

## 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.
