Detailed Description

template<class BASE, class INFO = BASE>
class SimpleKeyingInterfaceImpl< BASE, INFO >

Provides a base implementation of SimpleKeyingInterface.

Template Parameters

BASE	a SimpleKeyingInterface derived class
INFO	a SimpleKeyingInterface derived class

SimpleKeyingInterfaceImpl() provides a default implementation for ciphers providing a keying interface. Functions are virtual and not eligible for C++11 constexpr-ness.

Member Function Documentation

MinKeyLength()

template<class BASE , class INFO = BASE>

size_t SimpleKeyingInterfaceImpl< BASE, INFO >::MinKeyLength ( ) const

inline

The minimum key length used by the algorithm.

Returns

minimum key length used by the algorithm, in bytes

Definition at line 262 of file seckey.h.

MaxKeyLength()

template<class BASE , class INFO = BASE>

size_t SimpleKeyingInterfaceImpl< BASE, INFO >::MaxKeyLength ( ) const

inline

The maximum key length used by the algorithm.

Returns

maximum key length used by the algorithm, in bytes

Definition at line 267 of file seckey.h.

DefaultKeyLength()

template<class BASE , class INFO = BASE>

size_t SimpleKeyingInterfaceImpl< BASE, INFO >::DefaultKeyLength ( ) const

inline

The default key length used by the algorithm.

Returns

default key length used by the algorithm, in bytes

Definition at line 272 of file seckey.h.

GetValidKeyLength()

template<class BASE , class INFO = BASE>

size_t SimpleKeyingInterfaceImpl< BASE, INFO >::GetValidKeyLength ( size_t  keylength ) const

inline

Provides a valid key length for the algorithm.

Parameters

keylength

the size of the key, in bytes

Returns

the valid key length, in bytes

keylength is provided in bytes, not bits. If keylength is less than MIN_KEYLENGTH, then the function returns MIN_KEYLENGTH. If keylength is greater than MAX_KEYLENGTH, then the function returns MAX_KEYLENGTH. if If keylength is a multiple of KEYLENGTH_MULTIPLE, then keylength is returned. Otherwise, the function returns a lower multiple of KEYLENGTH_MULTIPLE.

Definition at line 283 of file seckey.h.

IVRequirement()

template<class BASE , class INFO = BASE>

SimpleKeyingInterface::IV_Requirement SimpleKeyingInterfaceImpl< BASE, INFO >::IVRequirement ( ) const

inline

The default IV requirements for the algorithm.

The default value is NOT_RESYNCHRONIZABLE. See IV_Requirement in cryptlib.h for allowed values.

Definition at line 288 of file seckey.h.

IVSize()

template<class BASE , class INFO = BASE>

unsigned int SimpleKeyingInterfaceImpl< BASE, INFO >::IVSize ( ) const

inline

The initialization vector length for the algorithm.

IVSize is provided in bytes, not bits. The default implementation uses IV_LENGTH, which is 0.
