This is not an issue but a question. I'm porting this code to vb.net for my HA application. So far all code works and is checked against the PY implementation but I can't figure out this code

def applySamyGOKeyTransform(input):
r = Rijndael(bytes.fromhex(keys.transKey))
return r.encrypt(input)

.net has AES and Rijdael but they return different results from what the PY code returns. All AES and SHA1 code in this PY project I figured out how to use with .NET but the above I can't figure out. Rijndael is supposed to be AES but you guys picked specifically an flavor of RIjndael. Any idea why? Any idea how this is different from AES? Specific setting?

I'm executing smartcrypto.py with sudo ./smartcrypto.py and I'm getting the following errors

from: can't read /var/mail/__future__

./smartcrypto.py: 3: ./smartcrypto.py: import: not found

./smartcrypto.py: 18: ./smartcrypto.py: lastRequestId: not found
./smartcrypto.py: 19: ./smartcrypto.py: Syntax error: "(" unexpected

I have run the script and pin is accepted. But now how do I find my token? What line is it in?

The connection to the TV worked without any issue but when trying to send a key to the TV nothing happens.
Via:

connection.recv()
print(connection.connected)

I can see that the script connected to the TV but nothing will happen, no matter what button I try to send.
Is there a solution to this problem?

Hey @eclair4151,

Your code works great with my UE55HU7505 (2014?) TV. But i can't turn the TV ON with this code. Should this SmartCrypto also support that feature?

Traceback (most recent call last):
File "smartcrypto.py", line 126, in
output = HelloExchange(tvPIN)
File "smartcrypto.py", line 68, in HelloExchange
return crypto.parseClientHello(clientHello, hello_output['hash'], hello_output['AES_key'], UserId)
File "/home/lebhack/SmartCrypto-master/PySmartCrypto/crypto.py", line 79, in parseClientHello
secret = bytes.fromhex(hex(pow(bnPGx, bnPrivateKey, bnPrime)).rstrip("L").lstrip("0x"))
ValueError: non-hexadecimal number found in fromhex() arg at position 255

i got:
pEncWBGx: "redacted"
pEncGx: "redacted"
pGx: "redacted"
cant get the CTX code

Is there any way to proceed from this point?

HI @eclair4151,

I have an issue with my tv (J5500), I am able to get the token and Id session, and the work, I can send commands to the TV, but when I turn off and then ON the TV, I need to re-pair the TV again because TV seems not to receive any command.

Hi,
I ' ve tried to send command on a model J and the Tv seems not understanding the command.
The handshake part of the communication process works fine.

Have you managed to send successfully a command andon which Tv model.
Thanks !

Goal
I would like to install this on a Raspbian. Goal is to use it with node-red and over SSH.

Problem:

1. Clone this repository seems not enough. What additional Software do I need?
   [Edit] Solved - It works if I use python3 smartcrypto.py
2. According to the README.md I have to use the last line in smartcrypto.py but I do not understand how a command line should look like

Hi,
can I please get help while executing:

python3 PySmartCrypto/smartcrypto.py Traceback (most recent call last): File "PySmartCrypto/smartcrypto.py", line 2, in <module> import crypto File "/root/temp/SmartCrypto-master/temp/SmartCrypto/PySmartCrypto/crypto.py", line 2, in <module> from Crypto.Cipher import AES ImportError: No module named 'Crypto'

Any ideas how I can fix this?

I have a QN65Q6FNA.
I do not get a pin page on my display when I run the command "ws://10.0.0.243:8001/ws/app/CloudPINPage".

if I run this from the WS google extension I get:
{
"data": {
"clients": [
{
"attributes": {
"name": null
},
"connectTime": 1559090240610,
"deviceName": "Smart Device",

}
],
"id": "ac9d77c9-af62-4f6b-b366-14e6d58d99e5"
},
"event": "ms.channel.connect"
}

I have tried so many different Samsung control python scripts and cannot get anything to work.
Any help would be great.

Hi,

after I run

python smartcrypto.py

I got the same issue after I input then PIN back

Current state: stopped
Pin NOT on TV
Please enter pin from tv: 9220
Got pin: '9220'
