Description

The crypt-fog package is a simple encryption mechanism, but slightly better
than Rot13.  It's primary goal is to provide a reasonable amount
of obfuscation without having to resort to public/private key
exchanges, etc.

For hyper-sensitive data I recommend using a more advanced encryption
scheme.

In addition to the module, a stand-alone program is included called
"quickenc" that takes both a string and a number as arguments and returns
your encrypted string.  You can then copy/paste that string to a .rc file.
Just remember the number you picked in order to decrypt it.

Usage: ruby quickenc.rb -s "hello" -d 1688
       ruby quickenc.rb -f "test.txt" -d 1066

Modify the shebang line as needed.

Installation

ruby test/tc_fog.rb (optional)
ruby install.rb

Synopsis

include Crypt
s = Fog.new("hello",2003)
p s # ";8??B"
p s.decrypt # "hello"

Fog.decrypt(";8??B",2003) # "hello"

Constants

VERSION

The current version of the module, returned as a String.

Class Methods

Fog.new(string, degree=13)

Creates and returns a new Fog object, which is your obfuscated string.
The degree is the value used to obfuscate the string.

Means of encryption not provided here. You'll have to look at the code. :)

Fog.decrypt(string, degree=13)

Returns a (presumably) decrypted String.  Should be used when the string
comes from an external source.

Instance Methods

Fog#decrypt

Returns a decrypted String, using the degree that was provided during
initialization.
