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.

Member Function Documentation

makeKey() [1/2]

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

makeKey() [2/2]

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
