100	MV_ENC_FUNC	Encrypts functions	article	2025-05-01T18:47:58-05:00	2025-05-01T18:47:58-05:00

declare function MV_ENC_FUNC<A..., R...>(vmFunction: (A...) -> R..., encryptKey: string, decryptKey: string): (A...) -> R...

will virtualize and encrypt the passed function constant with the provided encryptKey. Then decryptKey is evaluated at runtime to grab the key.

Valid Usage

local total = 0

local getKey = MV_VM(function()
  -- WARNING: this is just an example! don't do this
  return "pass" .. "word123"
end)

for i = 1, 10 do
  -- referenced upvalues will be captured
  MV_ENC_FUNC(function()
    print("in virtualized function # 1", i)
    total = total + i
  end, "password123", getKey())()
end

return total
