Re: Assistance with my settings class (Python) This is where I have to point out that you just posted all the info that any of us would need to trivially decrypt your files.

Hi.The error log returns the following errors when I run.dicdata = data.decrypt(dicdata, self.key)decryptor = AES.new(key, AES.MODE_CFB, iv)return _create_cipher(sys.modules[__name__], key, mode, *args, **kwargs)return modes[mode](factory, **kwargs)raise ValueError("Incorrect IV length (it must be %d bytes long)" %ValueError: Incorrect IV length (it must be 16 bytes long)

Re: Assistance with my settings class (Python)
Re: Assistance with my settings class (Python) @tunmi13 you only initialize sd within the try block so when that try block ends sd goes out of scope. Your later code tries to use it and then errors as a result. Your excepts are using the pass statement so you aren't seeing any errors.

Re: Assistance with my settings class (Python)
From what I can see, you are trying to read a file as plain text, when actually you've written it as binarywhat you'd want to use when reading is the "rb" mode.And the issue I can also see, is that you are using a lot of try and except blocks, without actually specifing which exception to catch. Therefore adding these many try except blocks will just prevent you from actually finding out what's wrong.As a good rule of thumb, always catch the exceptions you need.Using just except without specifying any exception, is going to hide whatever other error you are getting.Also, when dealing with file handles, you could also consider using the finally clause to close it. Finally always executes whether the try operation was successful or not, and you do always want to close the file handleSo after my nonsensical talk, here should be a working class # I'll pretend that the modules have been importedclass SaveData: def __init__(self, filename, key): self.d = {} self.filename = filename self.key = key def load(self): sd = None # let's keep the future handle out of the try scope, so we can use it later dicdata = "" try: sd = open(self.filename, "rb") dicdata = sd.read() except FileNotFoundError: # exception raised when file not found pass finally: if sd: sd.close() # here we can decide to decrypt the data if a key is present if self.key != "": dicdata = data.decript(dicdata, self.key) # finally, let's load json self.d = json.loads(dicdata)in the future, you might want to explore also utilizing the with statement, when dealing with IO operations, it'll make your life much better in most casesI hope it made some sense. And if not feel free to ask.

Re: Assistance with my settings class (Python)
Re: Assistance with my settings class (Python) I also would suggest creating the file if it doesn't exist. LOL.

Re: Assistance with my settings class (Python)
Re: Assistance with my settings class (Python) LOL I don't think you know what I meant. Put 'rb', not 'r'. That does read binary. Also, it is generally bad practice to use a general except. Because they catch *everything*. E.G., SyntaxError, ValueError, any kind of error. Might I suggestexcept ValueError:Or whatever the Exception raised is.

Re: Assistance with my settings class (Python)
Re: Assistance with my settings class (Python) Yes, but if the file didn't exist and you tried to open the file anyways, it'd fail to open it, thus crashing the application. If it passes the statement the file probably doesn't exist.

Re: Assistance with my settings class (Python)
Re: Assistance with my settings class (Python) I don't have a tun of time at the moment, and will look more later, but try using rb when opening the file to read.

Assistance with my settings class (Python)
Hi all,I am trying to create a class that saves and reads settings, such as game settings, progress, etc. However my class doesn't seem to be working, and I was wondering if I could get some assistance with it.The code is below.import lucia
from lucia import data
import os
import json
if not lucia.running:
lucia.initialize()
class savedata:
def __init__(self,fn,key):
self.d = {}
self.filename = fn
self.key = key
def load(self):
dicdata = ""
try:
sd = open(self.filename,"r")
except:
pass
if self.key != "":
try:
dicdata = data.decrypt(sd.read(),self.key)
except:
pass
else:
try:
dicdata = sd.read()
except:
pass
try:
sd.close()
except:
pass
try:
self.d = json.loads(dicdata)
except:
pass
def read(self,dictkey):
if dictkey in self.d:
return self.d.get(dictkey)
else: pass
def add(self,dictkey,dictval):
self.d[dictkey] = dictval
def save(self):
savedict = json.dumps(self.d)
sd = open(self.filename,"wb")
if self.key != "":
savedict = data.encrypt(savedict,self.key)
sd.write(savedict)
sd.close()The class runs fine, and it even saves the data as it is supposed to, but it seems its not able to read it.Any help would be appreciated.Thanks.
