Member Function Documentation

static size_t VariableKeyLength< D, N, M, Q, IV_REQ, IV_L >::StaticGetValidKeyLength ( size_t  keylength)
inlinestaticinherited

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

Parameters
keylengththe 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.
