%description
An object of this type encapsulates a keyed instance of the Eksblowfish
block cipher, ready to encrypt and decrypt.

Eksblowfish is a variant of the Blowfish cipher, modified to make the key
setup very expensive. ("Eks" stands for "expensive key schedule".) This
doesn't make it significantly cryptographically stronger, but is intended
to hinder brute-force attacks. It also makes it unsuitable for any
application requiring key agility. It was designed by Niels Provos and
David Mazieres for password hashing in OpenBSD. See
Crypt::Eksblowfish::Bcrypt for the hash algorithm. See
Crypt::Eksblowfish::Blowfish for the unmodified Blowfish cipher.

Eksblowfish is a parameterised (family-keyed) cipher. It takes a cost
parameter that controls how expensive the key scheduling is. It also takes
a family key, known as the "salt". Cost and salt parameters together define
a cipher family. Within each family, a key determines an encryption
function in the usual way. See Crypt::Eksblowfish::Family for a way to
encapsulate an Eksblowfish cipher family.
