Detailed Description

Simple container for acceptable key lengths.

The KeyLength specifies the minimum and maximum byte sizes allowed for a key, as well as a "multiple" which the key size must evenly divide into.

As an example, if the key can be 4, 8 or 12 bytes, you can express this as

KeyLength keyLen( 4, 12, 4 );

If you want to express a KeyLength that takes any number of bytes (including zero), you may want to use

#include<limits>
KeyLength( 0, std::numeric_limits<int>::max(), 1 );

QCA::KeyLength::KeyLength	(	int	min,
		int	max,
		int	multiple

Member Function Documentation

int QCA::KeyLength::maximum

(

)

const [inline]

Obtain the maximum length for the key, in bytes.

Definition at line 639 of file qca_core.h.

int QCA::KeyLength::minimum

(

)

const [inline]

Obtain the minimum length for the key, in bytes.

Definition at line 634 of file qca_core.h.

int QCA::KeyLength::multiple

(

)

const [inline]

Return the number of bytes that the key must be a multiple of.

If this is one, then anything between minimum and maximum (inclusive) is acceptable.
