[HELP] Hello i need help for exploiting in a game that have securized the damage remote

Hey, 
here is my analyse:

local args = {
    [1] = 2,
    [2] = {
        [1] = 78,
        [2] = 58847,
        [3] = 12033162,
        [4] = 10835316,
        [5] = 4135116,
        [6] = 8232403
    },
    [3] = game:GetService("Players"):WaitForChild("sltbye1234").Character.RightUpperArm,
    [4] = CFrame.new(972.6941528320312, 25.247312545776367, -1012.1983642578125, 0.2905203402042389, 0, -0.9568688273429871, -0, 1, -0, 0.9568688273429871, 0, 0.2905203402042389)
}

game:GetService("ReplicatedStorage"):WaitForChild("remoteInterface"):WaitForChild("interactions"):WaitForChild("meleePlayer"):FireServer(unpack(args))

first arg is the slot of the weapon

third is the part to be touched

and fourth is the position of part

but second is requierd and cant be modified.

i searched a lot and found that every players instance has attributes that is very similar to second argument, so i damaged my alt and take the values to compare:

target:
_pk = 65537
_pq1 = 175
_pq2 = 2657817
_pq3 = 6656890
_pq4 = 6677074
_pq5 = 4678075
_pq6 = 3792163
_pqC = 6

me:
_pk = 65537
_pq1 = 121
_pq2 = 16154961
_pq3 = 1584909
_pq4 = 6382146
_pq5 = 7627837
_pq6 = 7186943
_pqC = 6

my conclusion is that the script encrypt the target values and server decrypt them and check if equal, i found a crypt module in replicatedstorage and here is the script decompiled:

https://pastebin.com/raw/p5b2syG7

so, now i thing pk means public key,
pk is the key for encrypting

pqC the the amount of keys to verify

and so pq(n) the keys

i tryed the functions with my pqs and pk but thers some bug, its hard to find how it works, can someone help me please ?
