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.
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.
