Basically, the plugin uses short alphanumeric ids instead of the actual numeric ones.

Auto increment ID (Primary key)Hashid
1 jR
100 g56

1000000 gQ3E6
100000000 gq4rA6

1000000000000 gLpmopgO6
100000000000000 g2pxZPZy16

Of course the actual hashids are always different and unique per system, based on the salt that was provided.
