## Member Function Documentation

## ◆ StaticGetValidKeyLength()

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

static size_t FixedKeyLength< N, IV_REQ, IV_L >::StaticGetValidKeyLength | ( | size_t | keylength | ) |
| inline static

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.

## ◆ MAX_KEYLENGTH

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

const int FixedKeyLength< N, IV_REQ, IV_L >::MAX_KEYLENGTH =N
| static

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

MAX_KEYLENGTH is provided in bytes, not bits

Definition at line 135 of file seckey.h.

## ◆ DEFAULT_KEYLENGTH

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

const int FixedKeyLength< N, IV_REQ, IV_L >::DEFAULT_KEYLENGTH =N
| static

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

DEFAULT_KEYLENGTH is provided in bytes, not bits

## ◆ IV_REQUIREMENT

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

const int FixedKeyLength< N, IV_REQ, IV_L >::IV_REQUIREMENT = IV_REQ
| static

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.

## ◆ IV_LENGTH

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

const int FixedKeyLength< N, IV_REQ, IV_L >::IV_LENGTH = IV_L
| static

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.
