@@ -8,11 +8,12 @@ sadly i didnt think about being able to update hashes, using the common init-upd
 this is a pretty big problem meaning the input must be given at once, this is better for passwords,
 but bad for big files. because of this, i decided not to support inputs over 2^64 characters (which is an
 insane amount anyways). i likely will go back and rewrite all of these to fix both of these issues.

 ```lua
-obj = llib.crypto.adler32_init()
