Yes, there is an issue with the password implementation. I do not know how to encode it. it is probably just a matter of reading the doc , though.... so help welcome here
from python-opcua.
Should this issue be combined into the other issue?
Do you know which documentation this may be covered in? I would be interested in trying to solve the issue.
from python-opcua.
yes there is already an issue on this #23 . you are welcome to try to solve this :-)
look at line 199 in client.py. We need to encrypt password and set correct encryption in line under.
To find out what should be there you can read the opc-ua specification (But I could not find anything) and/or start wireshark, set filter type to opcua, and connect with a client supporting encryption (uaexpert for example). then do the same with python-opcua and look at the difference in the ActivateSession message
from python-opcua.
btw what server are you using?
from python-opcua.
I am using an Arburg Injection Molding Machine that hosts its own opc-ua server
from python-opcua.
That's interesting!. Do you manage to connect if you disable password?
from python-opcua.
yesterday I registered a session between a client and a prosys server:
server return 2 supported PolicyId: username_basic256 and username_basic128
and security policy URI is set to http://opcfoundation.org/UA/SecurityPolicy#Basic256
when sending password in activateSession it refers to following EncryptionAlgorythm
http://www.w3.org/2001/04/xmlenc#rsa-oaep
I have no idea where the key for the encryption is taken from ...
from python-opcua.
I am not able to disable the password even though the security policy is none?
When connecting with UaExpert I see:
Found security policy 'http://opcfoundation.org/UA/SecurityPolicy#None'
ApplicationUri: 'uri://Arburg/App/Selogica/direct'
Looking at the Certificate UaExpert has with the server I can see that the Signature algorithm is sha1RSA and the Public key is RSA(1024 bits)
You can view the public key in the windows certificate Details?
I tried watching with wire shark but haven't figured anything out so far.
Where do you take the typed password out of the connection url?
from python-opcua.
password and encryption is supposed to be implemented for client now. Can someone test and resport?
from python-opcua.
I am having the worst time trying to get python with pycrypto setup on my new computer. I will be able to test this out on Wednesday assuming I get pycrypto working.
from python-opcua.
Master should not use pycrypto but cryptography module... But I am not sure
all patch have been merged

I merged the last patch removing pycrypto ( I hope I did not break to much things for you @alkor !!!). Everything is in place for password encryption, but it might no be implemented yet. I am waiting for @alkor to merge the rest of his crypto stuff
from python-opcua.
No errors about pycrypto anymore.
from python-opcua.
Now I tested password encryption and it works against prosys server. Thanks @alkor
from python-opcua.
That's great!

I'm trying to connect using this: opc.tcp://admin:password@localhost:4096 and I get this error:
showing error: name 'uri' is not defined 1.
If I enable anonymous access I can do it.
from python-opcua.
@joaopmrod is the error you are getting similar to the one in this issue #135
unfortunately in that specific case I am not able to enable anonymous access
from python-opcua.
