Public Member Functions

 KeyLength (int min, int max, int multiple)
int maximum () const
int minimum () const
int multiple () const

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

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

Member Function Documentation

int QCA::KeyLength::maximum ( ) const

Obtain the maximum length for the key, in bytes.

Definition at line 729 of file qca_core.h.

int QCA::KeyLength::minimum ( ) const

Obtain the minimum length for the key, in bytes.

Definition at line 721 of file qca_core.h.

int QCA::KeyLength::multiple ( ) const

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.
