I am making a game. I am trying to save the data encrypted and then decrypt it. My code works fine without the encryption and decryption. The problem is that it does not save/load it when I am using encryption in it.
I have looked trough the code many times and tested it many times but it just does not work with encryption.
Here is the code (I am using loadsave library):
local M = {} local openssl = require( "plugin.openssl" ) local cipher = openssl.get\_cipher ( "aes-256-cbc" ) local myPassword = "example" local json = require("json") local \_defaultLocation = system.DocumentsDirectory local \_realDefaultLocation = \_defaultLocation local \_validLocations = { [system.DocumentsDirectory] = true, [system.CachesDirectory] = true, [system.TemporaryDirectory] = true } function M.saveTable(t, filename, location) if location and (not \_validLocations[location]) then error("Attempted to save a table to an invalid location", 2) elseif not location then location = \_defaultLocation end local path = system.pathForFile( filename, location) local file = io.open(path, "w") if file then local contents = json.encode(t) --encrypt that json string local encryptedData = cipher:encrypt( contents, myPassword ) file:write( encryptedData ) io.close( file ) return true else return false end end function M.loadTable(filename, location) if location and (not \_validLocations[location]) then error("Attempted to load a table from an invalid location", 2) elseif not location then location = \_defaultLocation end local path = system.pathForFile( filename, location) local file = io.open( path, "r" ) if file then -- read all contents of file into a string local contents = file:read( "\*a" ) --decrypt the string that we have retrieved local decrypted = cipher:decrypt ( contents, myPassword ) local myTable = json.decode( decrypted ) print( decrypted ) io.close( file ) return myTable end return nil end function M.changeDefault(location) if location and (not location) then error("Attempted to change the default location to an invalid location", 2) elseif not location then location = \_realDefaultLocation end \_defaultLocation = location return true end function M.print\_r ( t ) local print\_r\_cache={} local function sub\_print\_r(t,indent) if (print\_r\_cache[tostring(t)]) then print(indent.."\*"..tostring(t)) else print\_r\_cache[tostring(t)]=true if (type(t)=="table") then for pos,val in pairs(t) do if (type(val)=="table") then print(indent.."["..pos.."] =\> "..tostring(t).." {") sub\_print\_r(val,indent..string.rep(" ",string.len(pos)+8)) print(indent..string.rep(" ",string.len(pos)+6).."}") elseif (type(val)=="string") then print(indent.."["..pos..'] =\> "'..val..'"') else print(indent.."["..pos.."] =\> "..tostring(val)) end end else print(indent..tostring(t)) end end end if (type(t)=="table") then print(tostring(t).." {") sub\_print\_r(t," ") print("}") else sub\_print\_r(t," ") end print() end M.printTable = M.print\_r return M
