Decrypt AES with OpenSSL & Qt 5.5.1 Win32 VS2013

But again and I insist the IV handling is wrong. You should use the same IV for both encoding and decoding and following your code it's clearly not the case.
The IV should change each time you encode your data though to avoid repeat attack.

I am not involved in the encoding part. I did not write one single code for encoding. I get 3rd party XML files and i just want to decode them. To be very clear on this: I can't change the encoding, it is not my software, i do not develop it and i never had. I just got the source code for the de and encrypt part, so i may be able to import the XML files. I never wrote a single line VB code in my life. To be honest, i don't believe security is the issue, the developer just don't want anyone to be able to open it. That may not be an excuse for bad code but so far, i can't change it, i'm just happy now to be able to decode.
