Syntax

getscripthash(script: userdata): string | nil

Arguments

Name	Type	Description
`script`	`userdata`	Script object to hash. Supported ClassName values are ModuleScript, LocalScript, CoreScript, and Script with RunContext Client.

Returns

Name	Type	Description
`hash`	`string \| nil`	Uppercase SHA384 hex digest of the stored bytecode bytes, or nil when no usable embedded bytecode is available.

Description

Returns an uppercase SHA384 hex digest for the stored bytecode string of a Roblox script object. The argument must be object. The bytecode behavior accepts ClassName values ModuleScript, LocalScript, CoreScript, and Script. For Script, RunContext must be Client. If ClassName is missing, the function raises "Invalid Instance". If ClassName is not one of the supported script classes, it raises "Script expected". If the value is a Script with another RunContext, it raises "Expected a Script with RunContext set to Client". If the embedded bytecode reference is invalid or the stored bytecode length is 8 bytes or less, the function returns nil. Otherwise it hashes the exact stored bytecode bytes with SHA384 and returns the uppercase hex string. The function does not call DecompressBytecode and does not hash decompressed bytecode.

Call it with 1 parameter(s): script. The argument table explains which values are required and which ones only refine the behavior.

It returns hash (string | nil). Use the returns table to separate successful values from nil results and recoverable errors.

Example

Hash the bytecode of a supported Roblox script Instance when bytecode is available.

local targetScript

for _, descendant in ipairs(game:GetDescendants()) do
    if descendant:IsA("LuaSourceContainer") then
        targetScript = descendant
        break
    end
end

if targetScript then
    local hash = getscripthash(targetScript)
    print(hash)
end
