CRYPTOPP_CONSTANT() [1/6]

template<unsigned int N, unsigned int IV_REQ = SimpleKeyingInterface::NOT_RESYNCHRONIZABLE, unsigned int IV_L = 0>

FixedKeyLength< N, IV_REQ, IV_L >::CRYPTOPP_CONSTANT

(

DEFAULT_KEYLENGTH

= N

)

The default key length used by the algorithm provided as a constant.

DEFAULT_KEYLENGTH is provided in bytes, not bits

CRYPTOPP_CONSTANT() [2/6]

template<unsigned int N, unsigned int IV_REQ = SimpleKeyingInterface::NOT_RESYNCHRONIZABLE, unsigned int IV_L = 0>

FixedKeyLength< N, IV_REQ, IV_L >::CRYPTOPP_CONSTANT

(

IV_LENGTH

= IV_L

)

The default IV length used by the algorithm provided as a constant.

IV_LENGTH is provided in bytes, not bits. The default implementation uses 0.

FixedKeyLength< N, 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.

(

KEYLENGTH

= N

)

The default key length used by the algorithm provided as a constant.

KEYLENGTH is provided in bytes, not bits

FixedKeyLength< N, IV_REQ, IV_L >::CRYPTOPP_CONSTANT

(

MAX_KEYLENGTH

= N

)

The maximum key length used by the algorithm provided as a constant.

MAX_KEYLENGTH is provided in bytes, not bits

CRYPTOPP_CONSTANT() [6/6]

template<unsigned int N, unsigned int IV_REQ = SimpleKeyingInterface::NOT_RESYNCHRONIZABLE, unsigned int IV_L = 0>

FixedKeyLength< N, IV_REQ, IV_L >::CRYPTOPP_CONSTANT

(

= N

)

The minimum key length used by the algorithm provided as a constant.

MIN_KEYLENGTH is provided in bytes, not bits

StaticGetValidKeyLength()

template<unsigned int N, unsigned int IV_REQ = SimpleKeyingInterface::NOT_RESYNCHRONIZABLE, unsigned int IV_L = 0>

CRYPTOPP_STATIC_CONSTEXPR size_t CRYPTOPP_API FixedKeyLength< N, IV_REQ, IV_L >::StaticGetValidKeyLength ( size_t  keylength )

inline

The default key length for the algorithm provided by a static function.

Parameters

keylength

the size of the key, in bytes

The default implementation returns KEYLENGTH. keylength is unused in the default implementation.
