Re: [OT] Catalina users: recommended OPIE password generator for macOS

[Sam Ruby]

The following works on Ubuntu and Mac (including Catalina).  Put it in
a file named otp-md5 in your path and make it executable:

#!/usr/bin/env ruby
require 'otp' # gem install ruby-otp
require 'open3'

def OTP.md5(sequence, seed, password=nil)
  if password == nil
    begin
      print "password: "
      system 'stty -echo -icanon'
      password = $stdin.gets
      password.chomp! if password
    ensure
      system 'stty echo icanon'
      print "\r"
    end
  end

  if password.size < 10
    joined = seed + password
    password = joined[-10..-1]
    seed = joined[0...-10]
  end

  OTP.new(sequence.to_i, seed, password, 'md5')
end

if __FILE__ == $0
  password = OTP.md5(*ARGV[0..1])

  if RUBY_PLATFORM.include? 'darwin'
    Open3.capture2e('pbcopy', stdin_data: password)
  else not `which xclip`.empty?
    Open3.capture2e('xclip', '-select', 'clipboard', stdin_data: password)
  end

  puts password
end
