Problem with encryption?

[solars]

Hi there,

I seem to have a problem with encryption using the example. Somehow TTN does not decrypt or decrypts wrong.
I've outlined it in this discussion:
https://www.thethingsnetwork.org/forum/t/decrypt-aes-encoded-payload/11615/7

Is there anything wrong?

I think the Encrypt_Payload function uses the wrong key.
The function in Encrypt_V30.cpp encrypts the payload with:
AES_Encrypt(Block_A,NwkSkey);
This should be:
AES_Encrypt(Block_A,AppSkey);

I verified that the solution proposed by dhakkest is correct.
I changed line 86 in the encrypt_v30.cpp file,
the decrypts works !
