=head1 DESCRIPTION |
51
|
|
|
|
|
|
|
|
52
|
|
|
|
|
|
|
This module provides an object-oriented implementation of the |
53
|
|
|
|
|
|
|
B<Polybius square>, or B<Polybius checkerboard> using the |
54
|
|
|
|
|
|
|
Greek alphabet. This cipher is not cryptographically strong, |
55
|
|
|
|
|
|
|
nor completely round-trip-safe. And it requires you to write in |
56
|
|
|
|
|
|
|
Greek. |
