Detailed Description

Member Function Documentation

template<class BASE, class INFO = BASE>
size_t SimpleKeyingInterfaceImpl< BASE, INFO >::GetValidKeyLength ( size_t  keylength) const
inline

Provides a valid key length for the cipher.

Parameters
keylengththe size of the key, 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.

template<class BASE, class INFO = BASE>
SimpleKeyingInterface::IV_Requirement SimpleKeyingInterfaceImpl< BASE, INFO >::IVRequirement ( ) const
inline

The default IV requirements for the cipher.

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

Definition at line 278 of file seckey.h.

template<class BASE, class INFO = BASE>
unsigned int SimpleKeyingInterfaceImpl< BASE, INFO >::IVSize ( ) const
inline

The default initialization vector length for the cipher.

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