Issue with value decryption

[posteingang]

Hi,

we have an issue with the decryption of values which starts with '$7$' but only on certain systems.

We figured out that the problem happen on following line in lib/puppet_x/voxpupuli/splunk/util.rb
splunk_secret = IO.binread(secrets_file).chomp

With this following code we hexdump the readed string by ruby and the string from cat /opt/splunk/etc/auth/splunk.secret

require 'openssl'
require 'base64'
require 'hexdump'

secrets_file = "/opt/splunk/etc/auth/splunk.secret"

secret = "RXSD6HJ0djZLGzsByc9nPrnb0q.raCu3iOQJ0i2WQjhnro0qL0Oev/a7CXC5f8WUOZ.bn60vnq6d1WGkzvmhVxhVPk4vj8.TI2njFNyU5FIZLnQZwVtE4/UuGPZzFqY6Oj6.Es2btfLtn8j72k7joJ2zHSMwVneEXsmrgHPadNgoGx65y3bqtNMJCkowbGwAvNg1mpes2P9.QSkYi42zTx5.imVsX125wMlHLyOUnWN0WkeX0PyxSj1k3aZ8xU" # cat /opt/splunk/etc/auth/splunk.secret

splunk_secret = IO.binread(secrets_file).chomp

puts splunk_secret
Hexdump.dump(splunk_secret)
puts "-------"
Hexdump.dump(secret)

The result is:

Where you can see there are difference .

If we change the problem line to splunk_secret = IO.binread(secrets_file).chop it works well.

Unfortunately I am not a dev. So someone else with more knowledge of ruby can validate the problem.
