perl-Authen-Passphrase

This is the base class for a system of objects that encapsulate
passphrases. An object of this type is a passphrase recogniser: its job is
to recognise whether an offered passphrase is the right one. For security,
such passphrase recognisers usually do not themselves know the passphrase
they are looking for; they can merely recognise it when they see it. There
are many schemes in use to achieve this effect, and the intent of this
class is to provide a consistent interface to them all, hiding the details.
The CPAN package Authen-Passphrase contains implementations of several
specific passphrase schemes in addition to the base class. See the specific
classes for notes on the security properties of each scheme. In new
systems, if there is a choice of which passphrase algorithm to use, it is
recommended to use the Authen::Passphrase::SaltedDigest manpage or the
Authen::Passphrase::BlowfishCrypt manpage. Most other schemes are too weak
for new applications, and should be used only for backward compatibility.
