;;; Commentary:
|
|
|
|
;; The entry point, `rot13-other-window', performs a Caesar cipher
|
|
;; encrypt/decrypt on the current buffer and displays the result in another
|
|
;; window. ROT13 encryption is sometimes used on USENET as a read-at-your-
|
|
;; own-risk wrapper for material some might consider offensive, such as
|
|
;; ethnic humor.
|
|
;;
|
|
;; Written by Howard Gayle.
|
|
;; This hack is mainly to show off the char table stuff.
|
|
;;
|
|
;; New entry points, `rot13', `rot13-string', and `rot13-region' that
|
|
;; performs Caesar cipher encrypt/decrypt on buffers and strings, was
|
|
;; added by Simon Josefsson.
