I want to generate username token id in the request header of a soap Request. I am using asp.net with c#.
I tried to generate Username token as below:
UsernameToken userToken = new UsernameToken(Username, Password, PasswordOption.SendHashed);
I am getting username token Id output as

SecurityToken-6d139161-338c-465c-a56b-62c7414f2eda

.
But In many sample soap request usernametoken id value seen as UsernameToken-DFDA939C85F8B13ADA154211040258026.
Please update which is the proper way to pass username token id in a soap request header.
