Hello, I found out your project and it's very interesting, by the way I wanted to try it but I got an issue :

5.0.38.3

Traceback (most recent call last):
  File "D:\Users\Brandon\Desktop\snap decrypt\decrypt.py", line 140, in <module>

Hi, i haven't tested the 5.0.38.3 version yet or the 8.0.0 version either. I'll be updating the script to follow the changes made in the application in a few days I suppose.

I have the same issue in 5.0.38.1. tried the latest version (9.x) and then downgraded to 5.0.38.3, then to 5.0.38.2 and then to 5.0.38.1, but I have the same issue on all 5.x versions. I tried by sending new snaps to myself for every version, but no luck.

Hi, have you tried doing it manually? Pulling the encrypted files from the internal memory then generating the md5 and decrypting "bananas1" file with aes.online-domain-tools.com? Did you Check that the "bananas" decrypted file makes any sense?

@zerokes is there no fix for decrypting files stored by v5.0.38.1. im also getting the same error as @linkpad!
