SourceExpress.ShorterGuid 2.0.0

SourceExpress.ShorterGuid

This library contains extension methods to generate a 26-character long string from the Guid, which is URL-safe and case-insensitive! It uses Base32 encoding with the following character set: ABCDEFGHIJKLMNOPQRSTUVWXYZ234567.

Inspired by CSharpVitamins.ShortGuid library which uses Base64 encoding and produces a 22-character long string, however it is case-sensitive!

Available on NuGet. To install, run the following command in the Package Manager Console:

PM> Install-Package SourceExpress.ShorterGuid

The Gist

It takes a standard guid like this:

7ff2d2cb-1e1d-41cc-b478-32adb96082bd

and shortens it to a smaller string like this:

ZPJPE7Y5D3GEDNDYGKW3SYECXU or zpjpe7y5d3gedndygkw3syecxu

Using the ShorterGuid

The ShorterGuid provides two extension methods for Guid class:

var guid = Guid.NewGuid();  // 7ff2d2cb-1e1d-41cc-b478-32adb96082bd
var shorterGuid = guid.ToShorterString(); // ZPJPE7Y5D3GEDNDYGKW3SYECXU

var guid = Guid.NewGuid();  // 7ff2d2cb-1e1d-41cc-b478-32adb96082bd
var shorterGuid = guid.ToLowerShorterString(); // zpjpe7y5d3gedndygkw3syecxu

If you need to get Guid from the ShorterGuid string, you can do that using second extension method:

var shorterGuid = "ZPJPE7Y5D3GEDNDYGKW3SYECXU"; // or "zpjpe7y5d3gedndygkw3syecxu"
var guid = shorterGuid.FromShorterString(); // 7ff2d2cb-1e1d-41cc-b478-32adb96082bd

Methods contain some internal error handling like wrong character or incorrect length of the ShorterGuid. See test project for more details.
