GetRoundsAndThrowIfInvalid()

template<unsigned int D, unsigned int N = 1, unsigned int M = INT_MAX>

unsigned int VariableRounds< D, N, M >::GetRoundsAndThrowIfInvalid ( const NameValuePairs &  param, const Algorithm *  alg  )

inlineprotected

Validates the number of rounds for an algorithm.

Parameters

param	the candidate number of rounds
alg	an Algorithm object used if the number of rounds are invalid

Returns

the number of rounds for the algorithm

Exceptions

InvalidRounds

if the number of rounds are invalid

GetRoundsAndThrowIfInvalid() validates the number of rounds and throws if invalid.

Definition at line 108 of file seckey.h.

StaticGetDefaultRounds()

template<unsigned int D, unsigned int N = 1, unsigned int M = INT_MAX>

CRYPTOPP_STATIC_CONSTEXPR unsigned int VariableRounds< D, N, M >::StaticGetDefaultRounds ( size_t  keylength )

inline

The default number of rounds for the algorithm based on key length provided by a static function.

Parameters

keylength

the size of the key, in bytes

keylength is unused in the default implementation.

Definition at line 77 of file seckey.h.

ThrowIfInvalidRounds()

template<unsigned int D, unsigned int N = 1, unsigned int M = INT_MAX>

void VariableRounds< D, N, M >::ThrowIfInvalidRounds ( int  rounds, const Algorithm *  alg  )

inlineprotected

Validates the number of rounds for an algorithm.

Parameters

rounds	the candidate number of rounds
alg	an Algorithm object used if the number of rounds are invalid

Exceptions

InvalidRounds

if the number of rounds are invalid

ThrowIfInvalidRounds() validates the number of rounds and throws if invalid.
