FiveM JOAAT Hash Generator

Rockstar Games uses a non-cryptographic hash called JOAAT (Jenkins One-At-A-Time) for every named asset in GTA V — vehicles, weapons, peds, particles, animation clips, sound events, interior hashes. When you call a native like CreateVehicle('adder', ...) or GiveWeaponToPed(ped, 'WEAPON_ASSAULTRIFLE', ...), FiveM converts the string to its JOAAT hash internally, but sometimes you need the raw number for performance-critical code, serialized data, or hardcoded hash lookups.

This generator computes the JOAAT hash live as you type. Input is lowercased first (Rockstar's convention), then fed through the Jenkins OAAT algorithm. Output includes: Unsigned 32-bit (use in C# `uint`), Signed 32-bit (what Lua's GetHashKey() returns), Hex (for reverse-engineering tools), and the exact GetHashKey() call to paste into your Lua scripts.

Batch mode: paste a list of model names or weapon names — one per line — and get the hash table all at once. Useful for building hardcoded hash lookups in your resources, generating a weapons database, or reverse-engineering entity IDs from a network capture.

Algorithm specifics: lowercase input, accumulate each byte into 32-bit h with `h = ((h + c) * 1025) XOR ((h + c) >> 6)` then a finalizer `h = ((h + h*8) XOR (h+h*8 >> 11)) * 32769`. Match this against the official CitizenFX source for any edge case.
