`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. There are no restrictions on the length or the allowed characters of the keys, only that they are the same.
|
|
|
|
## Valid Usage
|
|
```lua
|
|
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
|
|
```
|

{{% alert context="warning" text="**Note**: if your plan doesn't include virtualization support, `MV_ENC_FUNC` is a no-op where the passed function is mangled normally and not virtualized or encrypted!" /%}}
