Sqids (pronounced squids) is a small library that lets you generate YouTube-like IDs from numbers. It encodes numbers like 127 into strings like yc3, which you can then decode back into the original numbers. Sqids is useful for when you want to hide numbers (like sequential numeric IDs) into random-looking strings to be used in URLs and elsewhere. Sqids has features like unique IDs, multiple numbers bundling, profanity-free IDs, randomized output, support for all integral types, optimized performance, comprehensive testing, and CLS compliance. To get started, install the NuGet package or use the .NET CLI. Usage involves creating an instance of SqidsEncoder and encoding/decoding numbers. Customizations include altering the alphabet, minimum ID length, and blocklist.
