Description

A library for performing simple character rotation (i.e. Caesar Cipher)
encryption. There are many like it, but this one is mine.

Installation

gem install crypt-rot13

Synopsis

require 'crypt/rot13'

str = Crypt::Rot13.new("Hello World", 3) # Caesar cipher
puts str # "Khoor Zruog"

Notes

Not unicode friendly. Only works on ASCII values 65-90 and 97-122. Other
characters will effectively be ignored, i.e. remain the same.

See http://en.wikipedia.org/wiki/ROT13 for more on ROT13

Acknowledgements

Thanks go to Gaius Julius Caesar (d. 44 BC) for creating one of the first,
and most simple, encryption schemes. Hail Caesar!
