FastLib provides a "jar-like" format for Ruby libraries, with specific features for the Metasploit Framework

FastLib

FastLib provides a method to encode large directories of libraries into a single archive file. This is similar to capabilities like zip/ziprequire, except that it provides workarounds for __FILE__ references, arbitrary compression, and arbitrary encryption of file and name contents.

Usage

$ gem install fastlib

Store a library in a FastLib archive

$ fastlib create mylib.fastlib /path/to/mylib

Use that archive just by including the containing directory

$ ruby -r fastlib -I . ./myapp.rb

Store a library in a FastLib archive with compression

$ fastlib create -c mylib.fastlib /path/to/mylib

Store a library in a FastLib archive with default "encryption"

$ fastlib create -e 0 mylib.fastlib /path/to/mylib

Store a library in a FastLib archive with default "encryption" and compression

$ fastlib create -c -e 0 mylib.fastlib /path/to/mylib

Store a library in a FastLib archive with custom encryption and compression

$ fastlib create -I . -r mycrypto -c -e 0xdeadee mylib.fastlib /path/to/mylib

$ cat mycrypto.rb

    require 'openssl'
    
    class FastLib
    
        def self.encrypt_deadee00(data)
          # Encrypt
        end
    
        def self.decrypt_deadee00(data)
          # Decrypt
        end
    
    end
