Hi, thanks for this article on improving the password safety for wordpress sites.

I'm not a developer, just a wordpress user so hopefully someone can answer this.

At the github site it mentions you need to have PHP 5.5.0 for this plugin to work, but I'm not sure how to know if I have this or not. Is this something that would be within wordpress, or is it my host? Or maybe it's something I should have on my computer while installing the plugin?

Thanks in advance for your help. I have things like wordfence running, and use 35 character random passwords to try and keep it secure, but it appears I should be implementing this plugin as well or the rest could be for nothing.

Anyway, thanks again.
