hashid

Is this quicker than hashid (using an all-number alphabet)?

Also it is called Knuth's integer hash (not Kunth)

Wow, what a typo!

I don't think this method will be any slower than hashids. If you take a look at the Optimus class you wil see that the technique is super simple. I will do a benchmark soon, but performance won't be an issue ;)

These are the results for a simple benchmark that simply constructs both classes and then encodes and decodes an id for 100.000 times:

• Optimus: 452ms
• Hashids: 57.680s

Cool!
