|
inlinestatic |
Provides a valid key length for the algorithm 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.

◆ IV_REQUIREMENT
template<class T , unsigned int IV_REQ = SimpleKeyingInterface::NOT_RESYNCHRONIZABLE, unsigned int IV_L = 0>
The default IV requirements for the algorithm provided as a constant.
The default value is NOT_RESYNCHRONIZABLE. See IV_Requirement in cryptlib.h for allowed values.
Definition at line 232 of file seckey.h.
◆ IV_LENGTH
template<class T , unsigned int IV_REQ = SimpleKeyingInterface::NOT_RESYNCHRONIZABLE, unsigned int IV_L = 0>
The default initialization vector length for the algorithm provided as a constant.
IV_LENGTH is provided in bytes, not bits. The default implementation uses 0.
