Is there a keyword for decrypt ? (1 Viewer)

[ChrisDekker]

Hi all,

Having a transfer problem from a python script to lua.
heres the lua script i got so far

local my_secret_key = 5
function decrypt ( secret_string , secret_number ) do
  local result = ""
  for x in secret_string do
    result = result+chr( ord ( x ) ^ int (secret_number) )
    end
  return result
end
end

print(my_secret_key, "is my secret key")


print(decrypt("alq%lv%``k%b`m`lh" , my_secret_key ) )
print("is my secret phrase")

Where's my problem, can anybody help me ?
Thank you

Chris

It's not a keyword. There are very few of them, as you can see here.

If you'd like people to help you, you should at least post the error message.

You’re totally right, stupid rookie mistake. Heres the error message :


5 is my secret key

lua5.3: HelloWorld.lua:5: attempt to call a string value
stack traceback:
HelloWorld.lua:5: in function 'decrypt'
HelloWorld.lua:15: in main chunk
[C]: in ?

The problem is in how you built the for loop. That's not how it works in Lua (see here).

To iterate over the characters of a string you can use utf8.codes, for example:

for p, c in utf8.codes("il gatto e la volpe") do
    print(p, c, utf8.char(c))
end
