NAME

Digest::Oplop - Generate account passwords based on a nickname and a master password

VERSION

Version 0.01

SYNOPSIS

  use Digest::Oplop qw(oplop);
  my $password = oplop($master_password,$label);

DESCRIPTION

This module implements the Oplop hashing algorithm created by Brett Cannon http://code.google.com/p/oplop/. Oplop makes it easy to create unique passwords for every account you have. By using some math, Oplop only requires of you to remember account nicknames and a master password to create a very safe and secure password just for you.

Oplop combines the account nickname and master password to generate a eight character long hash, that should meet the most common criteria for passwords used on web sites.

EXPORT

Nothing is exported by default, but the function oplop can be if requested.

SUBROUTINES

oplop

This function takes two mandatory arguments, the master password and the label and returns the hashed password. Please refer to the SYNOPSIS for an example.

Please report any bugs or feature requests to bug-digest-oplop at rt.cpan.org, or through the web interface at "/rt.cpan.org/NoAuth/ReportBug.html?Queue=Digest- Oplop" in http:. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.

CAVEAT

The Python implementation is considered the canonical implementation of the algorithm, and although this library pass the oplop testsuite, there might be some cornercases where both implementations differ.
