资源说明：Very simple encryption for Ruby
## Description
The crypt-fog library is a simple encryption mechanism, but slightly better
than Rot13. Its primary goal is to provide a reasonable amount of
obfuscation without having to resort to public/private key exchanges, etc.
For truly sensitive data I recommend using a more advanced encryption scheme.
In addition to the module, a stand-alone program is included called
"fogenc" 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.
## Installation
gem install crypt-fog
## Command Line
```
fogenc -s "hello" -d 1688
fogenc -f "test.txt" -d 1066
```
## Synopsis
```ruby
require 'crypt/fog' # or 'crypt-fog'
include Crypt
s = Fog.new("hello",2003)
p s # ";8??B"
p s.decrypt # "hello"
Fog.decrypt(";8??B",2003) # "hello"
```
