Sqids .NET is the official .NET port of Sqids, a small library that generates short, URL-safe, unique-looking IDs from non-negative integers and decodes them back. It supports encoding multiple numbers into one ID, custom shuffled alphabets, minimum-length padding, and a profanity blocklist.

Use cases

• generate short unique ids from numbers in c#
• obfuscate sequential database primary keys in urls
• encode multiple numbers into one short id
• make youtube-like video ids in .net
• generate profanity-free url-safe identifiers
• create short confirmation codes for emails

When to choose

• you need reversible, collision-free short IDs from integers in a .NET app
• you want to hide sequential numeric IDs in URLs without encryption
• you need profanity-free, URL-safe identifiers
• you need to encode several numbers into a single compact ID

When to avoid

• you need encryption or protection of sensitive data — IDs are trivially decodable
• you need globally unique IDs for arbitrary data (use UUIDs instead)
• exposing user counts via decodable user IDs is a concern
