* Verifier process
|
|
* Pokemon Showdown - http://pokemonshowdown.com/

|

|
|
* This is just an asynchronous implementation of a verifier for a
|
|
* signed key, because Node.js's crypto functions are synchronous,
|
|
* strangely, considering how everything else is asynchronous.
|
|
*
|
|
* I wrote this one day hoping it would help with performance, but
|
|
* I don't think it had any noticeable effect.
