## What it is
A Go implementation of the Hashids algorithm, which encodes integers into short, unique, obfuscated string hashes with a configurable salt and minimum length. It also ships a small CLI tool for generating hashids from the command line.

## Use cases
- obfuscate database ids in urls
- generate short unique ids from integers
- encode integer arrays into reversible hash strings
- hide sequential record numbers from users
- decode hashids back to original integers
- generate hashids from the command line

## When to choose
- you need reversible, salted obfuscation of integer ids in a Go project
- you want compatibility with the standard Hashids spec across languages
- you need short non-sequential identifiers for public-facing urls

## When to avoid
- you need cryptographically secure encryption rather than obfuscation
- you need non-integer identifiers like uuids
- you need a maintained solution with frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, security, developer-tools
- domain: developer-tools, web-development
- platform: go, cli, cross-platform
- tags: hashids, id-obfuscation, short-ids, encoding, decoding, algorithms
