PW hashing with puppet parser function

0_pw_hash.rb

# lib/puppet/parser/functions/pw_hash.rb

module Puppet::Parser::Functions
  newfunction(:pw_hash, type: :rvalue) do |args|
    raise Puppet::ParseError, "pw_hash takes exactly two arguments, #{args.length} provided" if args.length != 2
    # SHA512 ($6), default number of rounds (5000)
    # rounds could be specified by prepending rounds=<n>$ parameter before the salt, i.e.
    # args[0].crypt("$6$rounds=50000$#{args[1]}")
    args[0].crypt("$6$#{args[1]}")
  end
end

user { 'root':
	ensure => present,
	password => pw_hash($root_pw, $root_salt),
}

Thanks. This helped me out a lot!

thanks!
I will just leave here an inline_template version

$pass='password'
$salt='salt'
user{
  "alise":
        ensure     => present,
        password   => inline_template("<%= '$pass'.crypt('\$6$$salt') %>"),
}

Nice pschyska, works like a charm.

Nice one

If you use stdlib, it includes a function that does this now:
