Detailed Description

Key derivation function provider.

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

Constructor & Destructor Documentation

QCA::KDFContext::KDFContext	(	Provider *	p,
		const QString &	type )

inline

Standard constructor.

Parameters

p	the provider associated with this context
type	the name of the KDF provided by this context (including algorithm)

virtual SymmetricKey QCA::KDFContext::makeKey	(	const SecureArray &	secret,
		const InitializationVector &	salt,
		unsigned int	keyLength,
		unsigned int	iterationCount )

pure virtual

Create a key and return it.

Parameters

secret	the secret part (typically password)
salt	the salt / initialization vector
keyLength	the length of the key to be produced
iterationCount	the number of iterations of the derivation algorithm

virtual SymmetricKey QCA::KDFContext::makeKey	(	const SecureArray &	secret,
		const InitializationVector &	salt,
		unsigned int	keyLength,
		int	msecInterval,
		unsigned int *	iterationCount )

pure virtual

Create a key and return it.

Parameters

secret	the secret part (typically password)
salt	the salt / initialization vector
keyLength	the length of the key to be produced
msecInterval	the maximum time to compute the key, in milliseconds
iterationCount	a pointer to store the number of iterations of the derivation algorithm
