Vfunlauncher.log

Hi, There is a file in Combat Arms LOG folder Called VfunLauncher.log and i assume it contains account keys (86 letter long & Keys are same all time for same account so its not temporary) and i wonder what can do with it. is it possible to login accounts with this keys without using VfunLauncher?
Since I don't know coding, getting from help u might be a good idea.
Thank u for responds already.

its not useful. It doesn't contain anything you think it contains.
