This is a JWT library that exists because I ran into issues with the more commonly used Firebase JWT library. It is very, very loosely based on it in but you'll probably not run into many familiar things.

I'll write a better readme Someday...

Why does this target PHP 5.6?????

The only core dependency this library has is PHP Sec Lib, which also targets PHP 5.6. Although I'm also doing it as a personal challenge to see if I can support this insane setup.
