def optparse
  OptionParser.new do |opts|
    opts.banner =<<-USAGE

Usage:

tokenifier [options] COMMAND 'custom string'

Commands:

s|secret - Generates secret string
e|encrypt - Does data encryption of any string data
d|decrypt - Does data decryption from hashed data.

NOTE: You have to use a permanent secret to decrypt a data.
      Tokinifier generates random secret string each execution time instead.

Examples:

 tokenifier encrypt "CUSTOM DATA"
 tokenifier decrypt "CUSTOM DATA"

 tokenifier --secret MYSECRET e "CUSTOM DATA"
 tokenifier --secret MYSECRET d "ENCRYPTED DATA"


USAGE

    opts.on('-s', '--secret SECRET', 'Using custom secret phrase') do |secret|
      options[:secret] = secret
    end

    opts.on('-h', '--help', 'Display this screen') do
      puts opts
      exit
    end
  end
end
