Ported from https://github.com/rs/xid - A fast, low allocation, zero config, thread-safe 12 byte UUID generator based on the Mongo Object Id algorithm.
ASP.NET Extensions to make it easy to create and use COMB (timestamped sequential) GUID variants for Microsoft SQL Server and PostgreSQL. See the GitHub site for more details.
A fast and modern .NET library to generate UUID/GUID that are either sequential and database friendly (versions 7), name based (versions 5) or random (version 4).
A Simple Unique Identifier (SUID) is (almost) unique like a GUID but only 7 characters !
There are five types of fixed size SUID :
* LettersOnlySuid : 14 lowercase letters
* UrlFriendlySuid : 10 url friendly characters
* FilenameSuid : 10 characters than can be used to create a filename
* Suid : 9...

Auto-increment IDs reveal sensitive information. UUIDs (also known as GUIDs) are inefficient as primary keys in a database. Having two different IDs is cumbersome and counterintuitive. We can do better.
