WS-Policy: UsernameToken with password digest

We have edited buitlin policy to add HashPassword as mentioned below

             <sp:UsernameToken sp:IncludeToken="">


With this change I am able to send nonce and created time in wsse:UsernameToken tag.
But the password is still is in plain text.

<wsse:UsernameToken wsu:Id=“UsernameToken-6”>wsse:Usernametest</wsse:Username><wsse:Password Type=“”>manage</wsse:Password><wsse:Nonce EncodingType=“”>KF8Ny8T1DjP8LNKEa4qDQQ==</wsse:Nonce>wsu:Created2016-09-12T11:15:33.169Z</wsu:Created></wsse:UsernameToken>

But our requirements is to pass the nonce, created time and password digest.
Please suggest how to proceed further.
