Title: Message Title

PUP-3386

Example: generating password hashes for users created by module. Usually generate function used for this with mkpasswd command invokation. But this requires installing additional things to puppet master (like whois package for Ubuntu). One more dislike is that when developing module on non-Linux machine it's hard to test this (no mkpassword on OS X at all).

Another approach is to use custom function that uses functionality of gem unix-crypt.

lib/puppet/functions/my_password.rb
require 'unix_crypt'

module Puppet::Parser::Functions
newfunction(:my_password, type: :rvalue) do \|args\|
password, salt, rounds = args[1], args[2], args[3]
UnixCrypt::SHA512.build(password, salt, rounds)
end
end

It's easy to maintain (gem specified in Gemfile) and test (works everywhere), but currently this again requires manual gem installation on Puppet master.
