An interface to libQRNG for mruby.

Prerequisites

• register an account on https://qrng.physik.hu-berlin.de
• download libQRNG from https://qrng.physik.hu-berlin.de/download
• MinGW users: "ar rcs libQRNG.a libQRNG.lib" to convert the import library
• setup your compiler's search directories (in build_config.rb):

conf.cflags << '-I"/path/to/libQRNG"'
conf.ldflags << '-L"/path/to/libQRNG"'

Installation

• use mgem (https://github.com/bovi/mgem) or add the gem by yourself to build_config.rb

Usage

qrng = QRNG.new 'AzureDiamond', 'hunter2', true  # username, password, use ssl (optional)
pw = qrng.password 13, 'ABCdef123'  # password_length, tobeused_password_chars (optional)
puts pw  # => 2dBfCC123CfeC
int = qrng.data :int  # :byte (String), :int (Fixnum), :double (Float [between 0 and 1])
puts int  # => 2143097836
int = qrng.data :int, 3
puts int  # => [-984391892, 1743334411, -1048288211]
qrng.disconnect

q = QRNG.new 'AzureDiamond', 'hunter2' do |qrng|
  puts qrng.connected?  # => true
  puts qrng.ssl? # => false
  floats = qrng[:double, 0xffff]
  puts floats  # => numbers, numbers everywhere
