getprotohash

Details#

Returns a 16-character hexadecimal fingerprint of a function prototype. For Luau it summarizes compiled code and selected metadata, not captured values or every constant value. For native functions it is session-dependent. It is not a cryptographic integrity proof.

Examples#

local function f() return 42 end
local hash = getprotohash(f)
print(hash, #hash) -- length 16
