TypeError: can only concatenate str about lg-gallery-decryptor

First of all iv is no secret value because it's just in plain sight in the image file itself.

Which Python version do you use? Only Python 3 is supported. Type python --version to clarify.

When you put in your gmail address, did you preserve the leading b? The line should look like this:

gmail = b'[email protected]'

Hope that helps.

I do use Python 3.9.1 and I did gmail like you said, only filled between '[email protected]' , didn't touch anything else and I got that error.

is it possible to work without gmail?
i had some e-mail address long time ago and which I remember them %100 and tested one by one but no luck, is this console error some how related with gmail or something else?

[kamicater]

I can confirm it's a bug. Thank you for pointing it out. It happened because I changed some code 'last minute'. It should be easily fixed.

No, the gmail address is required.

thank you very much, will be waiting for fix,
I wish I could write some code like you and help to fix before you write, so I can support too,

as I readed their pdf before, there was a way to without gmail, am I right wrong?

[kamicater]

Please tell me if that helped because I like to close the issue.

The gmail address is needed. But if you don't remember it can be decrypted from the image file itself. Altough this part of the paper is not included in this tool.

Thank you very much, it worked perfect.
as i see there is only little bug left, "decrypted" folder must be created before running script.
otherwise consol error appears but file is created same folder where .py runned.
if "decrypted" folder created, no error.

btw can you create tool or guide if we forget gmail address how to get it from the image file itself?

Regards, thank you again

You are correct, the handling regarding the decrypted directory could be improved. Also I should have stated that the images should be in a folder called encrypted. But this tool is just a 'quick and dirty' solution to retrieve lost images and then to throw it away. The code could be improved in many many ways.

This tool is the implementation of algorithm 4 in the mentioned paper. To retrieve the gmail address one need to implement algorithm 2. It's just a simple operation on LGEID2 with a constant value. I have no inclination to do so.

This issue is closed now. I'm glad I could help.

Hello, thank you for this code. I am trying to decrypt an old LG phone I broke a while back. I am in way, way over my head and I have been trying to get this work for over 5 hours now. Any help would be greatly appreciated. I am trying to decrypt over 274 .jpg and .mp4 and I haven't even got the first one finished yet :-(

I am using Python 3.11 should I be using something different?

I have my encrypted and decrypted files and my lgdecryptor in this folder:
C:\Users\mwall\Desktop\LG\decrypted
C:\Users\mwall\Desktop\LG\encrypted
C:\Users\mwall\Desktop\LG\lgdecryptor.py

I keep getting this error
C:\Users\mwall>Python C:\Users\mwall\Desktop\LG\lgdecryptor.py 20141123_174651.mp4 (2020_06_29 03_16_15 UTC).dm

FileNotFoundError: [Errno 2] No such file or directory: './encrypted\20141123_174651.mp4'

Am I supposed to change anything other than adding my e-mail in the code below?

def main():

# your gmail address on your phone when the files have been encrypted
gmail = b'[email protected]'

# folders of encrypted and decrypted files
encrypt_dir = './encrypted'
decrypt_dir = ''
