This is a ruby implementation of Oplop http://code.google.com/p/oplop/, supporting the long oplop variation (see: https://github.com/thedod/loplop).

gem install oplop

Oplop and Loplop. Long Oplop defaults to 16 characters and support <n>* label prefix for specifying length.

These will all produce the same password with the new default 16 character length:

Oplop::V1.password(:master => "master-password", :label => "nickname")
Oplop::V1.password(:master => "master-password", :label => "16*nickname")
Oplop::V1.password(:master => "master-password", :label => "nickname", :length => 16)

These will all produce the same password with the legacy 8 character length:

Oplop::V1.password(:master => "master-password", :label => "*nickname")
Oplop::V1.password(:master => "master-password", :label => "8*nickname")
Oplop::V1.password(:master => "master-password", :label => "nickname", :length => 8)

This is a 20-character password

Oplop::V1.password(:master => "master-password", :label => "20*nickname")

This includes an oplop program that defaults to 8 character passwords. And a new loplop program that defaults to 16 character passwords.

Run oplop --help for more information.
