.Sh DESCRIPTION
|
|
|
|
|
.Nm
|
|
|
|
|
is a curses-based widget for solving Sunday-paper-type cryptograms
|
|
|
|
|
based on substitution ciphers.
|
|
|
|
|
A random cleartext is chosen using
|
|
|
|
|
.Xr fortune 6
|
|
|
|
|
and a random substitution key is generated.
|
|
|
|
|
.Pp
|
|
|
|
|
The ciphertext is displayed.
|
|
|
|
|
Typing a letter changes the key so that the letter under the cursor
|
|
|
|
|
maps to the newly typed letter, and updates the display accordingly.
|
|
|
|
|
Use Emacs-type cursor commands to move around.
|
|
|
|
|
Enter a tilde
|
|

|
to quit.
|
|
|
|
|
Press asterisk
|
|
|
|
|
.Pq *
|
|
|
|
|
to enter an easier mode where correct letters are displayed in
|
|
|
|
|
boldface.
