CRYPTOPP_CONSTANT (MIN_KEYLENGTH=T::MIN_KEYLENGTH) | |
The minimum key length used by the algorithm provided as a constant. | |
CRYPTOPP_CONSTANT (MAX_KEYLENGTH=T::MAX_KEYLENGTH) | |
The maximum key length used by the algorithm provided as a constant. | |
CRYPTOPP_CONSTANT (DEFAULT_KEYLENGTH=T::DEFAULT_KEYLENGTH) | |
The default key length used by the algorithm provided as a constant. | |
CRYPTOPP_CONSTANT (IV_REQUIREMENT=IV_REQ) | |
The default IV requirements for the algorithm provided as a constant. | |
CRYPTOPP_CONSTANT (IV_LENGTH=IV_L) | |
The default initialization vector length for the algorithm provided as a constant. | |
CRYPTOPP_STATIC_CONSTEXPR size_t CRYPTOPP_API | StaticGetValidKeyLength (size_t keylength) |
Provides a valid key length for the algorithm provided by a static function. | |
Provides key lengths based on another class's key length.
T | another FixedKeyLength or VariableKeyLength class |
IV_REQ | the IV requirements |
IV_L | default IV length, in bytes |
SameKeyLengthAs< T, IV_REQ, IV_L >::CRYPTOPP_CONSTANT | ( | DEFAULT_KEYLENGTH | = T::DEFAULT_KEYLENGTH | ) |
The default key length used by the algorithm provided as a constant.
MIN_KEYLENGTH is provided in bytes, not bits
SameKeyLengthAs< T, IV_REQ, IV_L >::CRYPTOPP_CONSTANT | ( | IV_LENGTH | = IV_L | ) |
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.
SameKeyLengthAs< T, IV_REQ, IV_L >::CRYPTOPP_CONSTANT | ( | IV_REQUIREMENT | = IV_REQ | ) |
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.
SameKeyLengthAs< T, IV_REQ, IV_L >::CRYPTOPP_CONSTANT | ( | MAX_KEYLENGTH | = T::MAX_KEYLENGTH | ) |
The maximum key length used by the algorithm provided as a constant.
MIN_KEYLENGTH is provided in bytes, not bits
SameKeyLengthAs< T, IV_REQ, IV_L >::CRYPTOPP_CONSTANT | ( | MIN_KEYLENGTH | = T::MIN_KEYLENGTH | ) |
The minimum key length used by the algorithm provided as a constant.
MIN_KEYLENGTH is provided in bytes, not bits

inline |
Provides a valid key length for the algorithm 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.
