# getscripthash

> 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.

<div className="real-function-page">
  ```lua theme={null}
  getscripthash(script: userdata): string | nil
  ```

  ## Arguments

  <ParamField path={"script"} type={"userdata"} required>
    Script object to hash. Supported ClassName values are ModuleScript, LocalScript, CoreScript, and Script with RunContext Client.
  </ParamField>

  ## Returns

  <ResponseField name={"hash"} type={"string | nil"}>
    Uppercase SHA384 hex digest of the stored bytecode bytes, or nil when no usable embedded bytecode is available.
  </ResponseField>

  ## Example

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

  ```lua theme={null}
  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
  ```
</div>
