Hi everyone,
I’m using this client to test my OPC-UA server.
I’ve coded it with the aid of the open62541 libraries.
I’m trying to set the login in my server.
I’m not able to login the user from my client, because it’s rightly encrypted, and I cannot match passwords and users.
So now, I would like to ask you to tell me, if possible, what method have been used in this software.
Thank you
Sirious

Hi,

The logic is defined in the OPC UA Specification. It is complex. In practice it depends on the EndpointDescriptions provided by the server. Please read at least the following:

1.03 Part 4 section 5.6.3 “ActivateSession”, section 7.36 “UserIdentityToken” and subsections.
1.03 Part 7 for the encryptionAlgorithm URIs for the AsymmetricEncryptionAlgorithm

Measurements for OPC UA PubSub over TSN
It is latency and jitter measurements for OPC UA PubSub over TSN based on open6251.
This is the second release candidate of what will become open62541 v0.3. The API has been frozen and only backwards-compatible patches will be applied before v0.3. Compared to the RC1 (0.3-rc1) this version includes additional bugfixes and small improvements under the hood while keeping the same API as 0.3-rc1.
