We are using username and password for connect to OPC Server, with

client.setUserIdentity(new UserIdentity(“my_name”, “my_password”));

Is there any password encryption methods by default, else how we can encrypt our password ?

The server endpoint defines the encryption algorithm to use for passwords (UserTokenPolicy) and the client should use the defined one. The SampleConsoleServer, for example initialises the user name policy with

server.addUserTokenPolicy(UserTokenPolicy.SECURE_USERNAME_PASSWORD);

Thanks

How we can define the UserTokenPolicy at client side, Now we are using

client.setUserIdentity(new UserIdentity(username, password));

You define the policy by selecting the UserIdentity type: if you use the name and password, the respective policy will be selected. I should have shown all the policies that are defined in SampleConsoleServer:

server.addUserTokenPolicy(UserTokenPolicy.ANONYMOUS);
server.addUserTokenPolicy(UserTokenPolicy.SECURE_USERNAME_PASSWORD);
server.addUserTokenPolicy(UserTokenPolicy.SECURE_CERTIFICATE);

It is true, though, that should the server define several policies per UserIdentity type, then we don’t have a way to select the used policy at the moment.
