for the "textutils.unserialize" add this function (got it from google)
Code:
textutils = {}
textutils.unserialize = function(s)
    if type( s ) ~= "string" then
        error( "bad argument #1 (expected string, got " .. type( s ) .. ")", 2 )
    end
    local func = load( "return "..s, "unserialize", "t", {} )
    if func then
        local ok, result = pcall( func )
        if ok then
            return result
        end
    end
    return nil
end


and second error is
the code checks a file, if u dont have a file it will not work

on line 899 :
Code:
local f = io.open("/public.key", "r")
local publicKey = textutils.unserialize(f:read("*a"))
f:close()
f = io.open("/private.key", "r")
local privateKey = textutils.unserialize(f:read("*a"))
f:close()

I revised it, but I still couldn't work.

Code:
textutils = {}
textutils.unserialize = function(s)
    if type( s ) ~= "string" then
        error( "bad argument #1 (expected string, got " .. type( s ) .. ")", 2 )
    end
    local func = load( "return "..s, "unserialize", "t", {} )
    if func then
        local ok, result = pcall( func )
        if ok then
            return result
        end
    end
    return nil
end
local f = io.open("public.key", "r")
local publicKey = textutils.unserialize(f:read("*a"))
print(f);
print(publicKey);
f:close()

f = io.open("private.key", "r")
local privateKey = textutils.unserialize(f:read("*a"))
f:close()


print:

Code:

error:[string "--

897:

Code:
if key.public then


Code:

   local exp
   if key.public then
      exp = bigint(key.public)
   else
      exp = bigint(key.private)
   end

   return tostring(modexp(bigint(number), exp, bigint(key.shared)))
end
