Summary0010441: RequestedLifetime not sent correctly in secure channel opening
Description

Problem Summary: The OPC UA client does not send the RequestedLifetime parameter correctly in secure channel opening requests, causing communication failures when the server returns a RevisedLifetime of 0.

Impact: OPC UA communication is entirely blocked, and secure connections cannot be established.

Action Required: Fix the client implementation to correctly send RequestedLifetime and handle scenarios where the server responds with unexpected values or 0 (default value sent).

Steps To Reproduce
  • Configure an OPC UA client to open a secure channel with an OPC server.
  • Change the RequestedLifetime to 300000
  • Ensure the client sends a secure channel opening request with the RequestedLifetime parameter.
  • To inspect the requests, you can use packet analysis software such as Wireshark.
  • Observe the server's response.
  • Check the default RequestedLifetime sent is 0 and the returned can be 0 (depends on server)
  • Check if the RevisedLifetime returned is 0 and if the client throws the error BadInvalidArgument.

the initial change is that the the CTT should request something like 10 sec for the default.
this issue should be cloned to test cases - we need to generate test cases for cases where server return a 0 (if a 0 is provided) - in general test cases around this issue
this issue should also be clone to part 4 and ask for a clarification on - is it ok for a server to return a 0?
