Crypt::Eksblowfish::Family 0.008

Crypt::Eksblowfish::Family is a Perl module from the Eksblowfish cipher family.

SYNOPSIS

use Crypt::Eksblowfish::Family;

$family = Crypt::Eksblowfish::Family->new_family(8, $salt);

$cost = $family->cost;
$salt = $family->salt;
$block_size = $family->blocksize;
$key_size = $family->keysize;
$cipher = $family->new($key);

An object of this class represents an Eksblowfish cipher family. It contains the family parameters (cost and salt), and if combined with a key it yields an encryption function. See Crypt::Eksblowfish for discussion of the Eksblowfish algorithm.

It is intended that an object of this class can be used as the "-cipher" parameter to Crypt::CBC and similar systems. Normally that parameter is the name of a class, such as "Crypt::Rijndael", where the class implements a block cipher algorithm. The class provides a new constructor that accepts a key. In the case of Eksblowfish, the key alone is not sufficient. An Eksblowfish family fills the role of block cipher algorithm. Therefore a family object is used in place of a class name, and it is the family object the provides the new constructor.
