Member Function Documentation

static size_t VariableKeyLength< D, N, M, 1 , SimpleKeyingInterface::NOT_RESYNCHRONIZABLE , 0 >::StaticGetValidKeyLength ( size_t  keylength  )  [inline, static, inherited]

Provides a valid key length for the cipher provided by a static function.

Parameters:
keylength the size of the key, in bytes

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 keylength is a multiple of KEYLENGTH_MULTIPLE, then keylength is returned. Otherwise, the function returns keylength rounded down to the next smaller multiple of KEYLENGTH_MULTIPLE.

keylength is provided in bytes, not bits.

static unsigned int VariableRounds< D, 1 , INT_MAX >::StaticGetDefaultRounds ( size_t  keylength  )  [inline, static, inherited]

The default number of rounds for the cipher 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.
